Preoperative and intraoperative tirofiban during endovascular thrombectomy in large vessel occlusion stroke due to large artery atherosclerosis. Eur J Neurol 2024; 31:e16419. [PMID: 39072930 DOI: 10.1111/ene.16419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2024] [Revised: 06/27/2024] [Accepted: 07/09/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND AND PURPOSE The aim of this study is to investigate the efficacy and safety of preoperative versus intraoperative tirofiban in patients with large vessel occlusion (LVO) due to large artery atherosclerosis (LAA). METHODS This is a retrospective multicenter cohort study based on the RESCUE-RE (Registration Study for Critical Care of Acute Ischemic Stroke After Recanalization) trial enrolling patients with anterior circulation LVO classified as LAA within 24 h of onset. Patients were divided into three groups: preoperative tirofiban (PT), intraoperative tirofiban (IT), and no tirofiban (NT). Propensity score matching (PSM) was used to balance baseline characteristics. The efficacy outcomes included 90-day functional independence (modified Rankin Scale score = 0-2) and early partial recanalization (EPR; defined as a modified Thrombolysis in Cerebral Infarction score = 1-2a). The safety outcomes included symptomatic intracranial hemorrhage (sICH). RESULTS A total of 104 matched triplets were obtained through PSM. Compared with NT, PT increased 90-day functional independence (60.8% vs. 42.3%, p = 0.008) and EPR (42.7% vs. 18.3%, p < 0.001) rate, with a tendency to increase the asymptomatic intracranial hemorrhage (aICH) proportion (28.8% vs. 18.3%, p = 0.072). Compared with IT, PT had a higher 90-day functional independence (60.8% vs. 45.2%, p = 0.025) and EPR (42.7% vs. 20.2%, p = 0.001) rate, with no significant difference in sICH (14.4% vs. 7.7%, p = 0.122) and aICH (28.8% vs. 21.2%, p = 0.200). Compared with NT, IT had a lower 90-day mortality rate (9.6% vs. 24.0%, p = 0.005). CONCLUSIONS Tirofiban shows good adjuvant therapy potential in acute ischemic stroke-LVO due to LAA patients. PT is associated with higher rates of EPR and better therapeutic efficacy. In addition, EPR may be a potential way to improve prognosis.

Abstract
RATIONALE Adjunct intra-arterial alteplase has been shown to potentially improve clinical outcomes in patients with large vessel occlusion (LVO) stroke who have undergone successful endovascular thrombectomy. Tenecteplase, known for its enhanced fibrin specificity and extended activity duration, could potentially enhance outcomes in stroke patients after successful reperfusion when used as an adjunct intra-arterial therapy. AIM To explore the safety and efficacy of intra-arterial tenecteplase after successful endovascular thrombectomy in patients with LVO stroke. SAMPLE SIZE To randomize 498 participants 1:1 to receive intra-arterial tenecteplase or no intra-arterial adjunctive thrombolysis therapy. METHODS AND DESIGN An investigator-initiated, prospective, randomized, open-label, blind-endpoint multicenter clinical trial. Eligible patients with anterior circulation LVO stroke presenting within 24 h from symptom onset (time last known well) and excellent to complete reperfusion (expanded Thrombolysis In Cerebral Infarction (eTICI) scale 2c-3) at endovascular thrombectomy are planned to be randomized. OUTCOMES The primary outcome is freedom from disability (modified Rankin Scale, mRS, of 0-1) at 90 days. The primary safety outcomes are mortality through 90 days and symptomatic intracranial hemorrhage within 48 h. DISCUSSION The POST-TNK trial will evaluate the efficacy and safety of intra-arterial tenecteplase in patients with LVO stroke and excellent to complete reperfusion.

Abstract
Stroke related to large vessel occlusion is a leading cause of disability and death worldwide. Advances in endovascular therapy to reopen occluded arteries have been shown to reduce patient disability and mortality. Expanded indications to treat patients with large vessel occlusion in the late window (>6 h from symptom onset), with basilar artery occlusion, and with large ischaemic core at presentation have enabled treatment of more patients with simplified imaging methods. Ongoing knowledge gaps include an understanding of which patients with large ischaemic infarct are more likely to benefit from endovascular therapy, the role of endovascular therapy in patients who present with low National Institutes of Health Stroke Scale scores or medium or distal vessel occlusion, and optimal management of patients with underlying intracranial atherosclerotic disease. As reperfusion can now be facilitated by intravenous thrombolysis, mechanical thrombectomy, or both, the development of cytoprotective or adjunctive drugs to slow infarct growth, enhance reperfusion, or decrease haemorrhagic risk has gained renewed interest with the hope to improve patient outcomes.

Abstract
BACKGROUND Intravenous thrombolysis is a standard treatment of acute ischemic stroke. The efficacy and safety of combining intravenous thrombolysis with argatroban (an anticoagulant agent) or eptifibatide (an antiplatelet agent) are unclear. METHODS We conducted a phase 3, three-group, adaptive, single-blind, randomized, controlled clinical trial at 57 sites in the United States. Patients with acute ischemic stroke who had received intravenous thrombolysis within 3 hours after symptom onset were assigned to receive intravenous argatroban, eptifibatide, or placebo within 75 minutes after the initiation of thrombolysis. The primary efficacy outcome, the utility-weighted 90-day modified Rankin scale score (range, 0 to 10, with higher scores reflecting better outcomes), was assessed by means of centralized adjudication. The primary safety outcome was symptomatic intracranial hemorrhage within 36 hours after randomization. RESULTS A total of 514 patients were assigned to receive argatroban (59 patients), eptifibatide (227 patients), or placebo (228 patients). All the patients received intravenous thrombolysis (70% received alteplase, and 30% received tenecteplase), and 225 patients (44%) underwent endovascular thrombectomy. At 90 days, the mean (±SD) utility-weighted modified Rankin scale scores were 5.2±3.7 with argatroban, 6.3±3.2 with eptifibatide, and 6.8±3.0 with placebo. The posterior probability that argatroban was better than placebo was 0.002 (posterior mean difference in utility-weighted modified Rankin scale score, -1.51±0.51) and that eptifibatide was better than placebo was 0.041 (posterior mean difference, -0.50±0.29). The incidence of symptomatic intracranial hemorrhage was similar in the three groups (4% with argatroban, 3% with eptifibatide, and 2% with placebo). Mortality at 90 days was higher in the argatroban group (24%) and the eptifibatide group (12%) than in the placebo group (8%). CONCLUSIONS In patients with acute ischemic stroke treated with intravenous thrombolysis within 3 hours after symptom onset, adjunctive treatment with intravenous argatroban or eptifibatide did not reduce poststroke disability and was associated with increased mortality.

Association of functional outcomes between intravenous tirofiban and endovascular thrombectomy in imaging-screened patients with large vessel occlusion stroke: a secondary analysis of randomized clinical trial. Int J Surg 2024; 110:5505-5517. [PMID: 38788200 PMCID: PMC11392134 DOI: 10.1097/js9.0000000000001666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Accepted: 05/09/2024] [Indexed: 05/26/2024]
Abstract
BACKGROUND In the RESCUE BT (endovascular treatment with versus without tirofiban for stroke patients with large vessel occlusion) trial, enrollment in extended time window was based on noncontrast computed tomography. To assess whether perioperative intravenous tirofiban would further enhance the clinical benefit of endovascular therapy in the RESCUE BT trial according to advanced imaging criteria based on current American Heart Association/American Stroke Association (AHA/ASA) guidelines. METHODS This is a secondary analysis of the RESCUE BT trial. Patients who were eligible for endovascular thrombectomy in the 6 h window and met the criteria of the DAWN or DEFUSE 3 trials in the extended window according to the AHA/ASA guidelines were analyzed. The primary outcome was the distribution of the 90-day modified Rankin Scale (mRS) scores. Safety outcomes included the incidence of symptomatic intracranial hemorrhage (sICH) within 48 h and 90-day mortality. RESULTS A total of 652 patients (319 in tirofiban group and 333 in placebo group) who meeting the AHA/ASA guidelines were included in this analysis, with median interquartile ranges (IQR) age of 68 (58-75) years, 278 (42.6%) were women. The median 90-day mRS score was 3 (IQR, 1-4) in the tirofiban group, and 3 (IQR, 1-4) in the placebo group. The adjusted common odds ratio (OR) for a lower level of disability with tirofiban than with placebo was 1.08 (95% CI: 0.83-1.42). The incidence of sICH [10.1% versus 6.3%; adjusted OR 1.70; (95% CI: 0.95-3.04)] was not significantly different between groups. However, intravenous tirofiban might be associated with lower disability level [adjusted common OR, 1.74 (95% CI: 1.14-2.65); P =0.01] in patients with large artery atherosclerosis. CONCLUSIONS There was no significant difference in the severity of disability at 90 days with intravenous tirofiban compared to placebo in patients who underwent endovascular therapy according to AHA/ASA guidelines. The authors observed potential benefits of tirofiban in patients with large artery atherosclerosis, but there was an increased risk of sICH in patients with cardioembolism stroke.

The effectiveness and safety of human urinary kallidinogenase in acute ischemic stroke patients undergoing endovascular therapy. J Cereb Blood Flow Metab 2024; 44:1565-1576. [PMID: 38459953 PMCID: PMC11418712 DOI: 10.1177/0271678x241238033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 12/30/2023] [Accepted: 01/17/2024] [Indexed: 03/11/2024]
Abstract
The effectiveness and safety of human urinary kallidinogenase (HUK) in acute ischemic stroke (AIS) patients undergoing endovascular therapy (EVT) due to large vessel occlusion (LVO) was unclear. A pooled analysis was performed using individual data from the DEVT and RESCUE BT trials. Patients were divided into two groups based on HUK treatment. The primary outcome was the 90-day modified Rankin Scale (mRS) score. Safety outcomes included 90-day mortality and symptomatic intracranial hemorrhage (sICH) within 48 hours. A total of 1174 patients were included in the study. Of these, 150 (12.8%) patients received HUK. The adjusted common odds ratio (OR) of the mRS score was 1.458 (95% confidence interval [CI] = 1.072-1.983; p = 0.016) favoring HUK. The incidence of sICH (2.0% vs. 8.6%; adjusted OR: 0.198; 95% CI: 0.061-0.638; p = 0.007) and mortality (11.3% vs.18.5%; adjusted OR: 0.496; 95% CI: 0.286-0.862; p = 0.013) was lower in HUK group than non-HUK group. This association was consistent with propensity score-matching and the inverse probability of treatment weighting analysis. In conclusion, HUK was safe and associated with a preferable prognosis in AIS patients due to LVO in the anterior circulation.

Abstract
Although immunotherapy is expanding treatment options for cancer patients, the prognosis of advanced cancer remains poor, and these patients must contend with both cancers and cancer-related thrombotic events. In particular, immune checkpoint inhibitors are associated with an increased risk of atherosclerotic thrombotic events. Given the fundamental role of platelets in atherothrombosis, co-administration of antiplatelet agents is always indicated. Platelets are also involved in all steps of cancer progression. Classical antithrombotic drugs can cause inevitable hemorrhagic side effects due to blocking integrin β3 bidirectional signaling, which regulates simultaneously thrombosis and hemostasis. Meanwhile, many promising new targets are emerging with minimal bleeding risk and desirable anti-tumor effects. This review will focus on the issue of thrombosis during immune checkpoint inhibitor treatment and the role of platelet activation in cancer progression as well as explore the mechanisms by which novel antiplatelet therapies may exert both antithrombotic and antitumor effects without excessive bleeding risk.

Safety and efficacy of tirofiban combined with intravenous thrombolysis and endovascular treatment in acute large vessel occlusion stroke. Clin Neurol Neurosurg 2024; 244:108463. [PMID: 39053321 DOI: 10.1016/j.clineuro.2024.108463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 07/14/2024] [Accepted: 07/20/2024] [Indexed: 07/27/2024]
Abstract
OBJECTIVE This study assesses the safety and efficacy of tirofiban for patients with large vessel occlusion stroke after intravenous thrombolysis. METHODS This study data was from SUSTAIN, DEVT, and RESCUE BT trials. According to whether the use of tirofiban who underwent endovascular treatment and preceding intravenous thrombolysis was divided into the tirofiban group and the no-tirofiban group. The safety outcomes were symptomatic intracranial hemorrhage, any intracranial hemorrhage within 48 h, and 3-month mortality. The efficacy outcome was defined as a score of 0-2 on the modified Rankin Scale scores at 3 months. RESULTS A total of 372 patients with intravenous thrombolysis were included in these SUSTAIN, DEVT, and RESCUE BT trials. Adjusted multivariate analysis showed that tirofiban with intravenous thrombolysis was not associated with symptomatic intracranial hemorrhage (aOR, 0.87; 95 % CI, 0.49-1.57; P=0.65), any intracranial hemorrhage within 48 h (aOR, 1.00; 95 % CI, 0.60-1.66; P=1.00), 3-month mortality (aOR, 1.10; 95 % CI, 0.56-2.19; P=0.78) and 3-month modified Rankin Scale scores 0-2 (aOR, 0.72; 95 % CI, 0.42-1.25; P=0.25) in patients with acute large vessel occlusion. In the subgroup analysis, we found that tirofiban was not recommended for females (aOR, 0.34; 95 % CI, 0.12-0.93), baseline Alberta Stroke Program Early CT Score≤9 (aOR, 0.37; 95 % CI, 0.18-0.76), and cardiogenic embolism (aOR, 0.36; 95 % CI, 0.14-0.97). CONCLUSION Tirofiban combined with intravenous thrombolysis in patients with acute large vessel occlusion may be safe. Further studies need to confirm the effectiveness of tirofiban after intravenous thrombolysis in different stroke etiology.

J Formos Med Assoc 2024:S0929-6646(24)00391-7.

Abstract
BACKGROUND AND PURPOSE To evaluate the effectiveness and safety of intravenous tirofiban before endovascular thrombectomy in subgroups of acute ischemic stroke patients with different degrees of leukoaraiosis (LA). METHODS Patients of the RESCUE BT trial whose LA grade could be assessed were included. Eligible patients were dichotomized into two strata according to the van Swieten scale (VSS) score, absent-to-moderate LA (VSS score <3) and severe LA (VSS score ≥3). Furthermore, patients were divided into tirofiban and placebo groups in each stratum. The primary outcome was the 90-day modified Rankin Scale (mRS) score. Safety outcome was radiological intracranial hemorrhage within 48 h. RESULTS 861 patients were included, 439 patients with absent-to-moderate LA and 422 patients with severe LA. There were no significant differences in 90-day mRS score between the tirofiban and placebo groups in either stratum (absent-to-moderate LA: adjusted OR 0.92 (95%CI, 0.66-1.28), P = 0.62; severe LA: adjusted OR 0.99 (95% CI, 0.69-1.42), P = 0.96). In the severe LA stratum, the occurrence of radiologic intracranial hemorrhage was greater in the tirofiban group compared to the placebo group. (35.7% vs 26.4%; adjusted OR, 1.72 (95% CI, 1.12-2.66); P = 0.014). However, no difference was observed in the absent-to-moderate LA stratum (33.2% vs 29.3%; adjusted OR, 1.15 (95% CI, 0.76-1.75); P = 0.51). CONCLUSION There was no significant difference in disability severity at 90 days when treating AIS patients using intravenous tirofiban before endovascular therapy, in either absent-to-moderate or severe LA strata. It should be noted that intravenous tirofiban before endovascular therapy increases the incidence of radiologic intracranial hemorrhage in patients with severe LA.

Stent Retriever AssIsted Lysis Technique with Tirofiban: A Potential Bailout Alternative to Angioplasty and Stenting. AJNR Am J Neuroradiol 2024:ajnr.A8374. [PMID: 38849135 DOI: 10.3174/ajnr.a8374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Accepted: 05/29/2024] [Indexed: 06/09/2024]
Abstract
BACKGROUND AND PURPOSE Angioplasty and stent placement have been described as a bailout technique in individuals with failed thrombectomy. We aimed to investigate Stent retriever AssIsted Lysis (SAIL) with tirofiban before angioplasty and stent placement. MATERIALS AND METHODS Patients from 2 comprehensive stroke centers were reviewed (2020-2023). We included patients with failed thrombectomy and/or underlying intracranial stenosis who received SAIL with tirofiban before the intended angioplasty and stent placement. SAIL consisted of deploying a stent retriever through the occluding lesion to create a bypass channel and infuse 10 mL of tirofiban for 10 minutes either intra-arterially or IV. The stent retriever was re-sheathed before retrieval. The primary end points were successful reperfusion (expanded TICI 2b-3) and symptomatic intracerebral hemorrhage. Additional end points included 90-day mRS 0-2 and mortality. RESULTS After a median of 3 (interquartile range, 2-4) passes, 44 patients received the SAIL bridging protocol with tirofiban, and later they were considered potential candidates for angioplasty and stent placement bailout (43.2%, intra-arterial SAIL). Post-SAIL successful reperfusion was obtained in 79.5%. A notable residual stenosis (>50%) after successful SAIL was observed in 45.7%. No significant differences were detected according to post-SAIL: successful reperfusion (intra-arterial SAIL, 80.0% versus IV-SAIL, 78.9%; P = .932), significant stenosis (33.3% versus 55.0%; P = .203), early symptomatic re-occlusion (0% versus 8.0%; P = .207), or symptomatic intracerebral hemorrhage (5.3% versus 8.0%; P = .721). Rescue angioplasty and stent placement were finally performed in 15 (34.1%) patients (intra-arterial SAIL 21.0% versus IV-SAIL 44%; P = .112). At 90 days, mRS 0-2 (intra-arterial SAIL 50.0% versus IV-SAIL 43.5%; P = .086) and mortality (26.3% versus 12.0%; P = .223) were also similar. CONCLUSIONS In patients with stroke in which angioplasty and stent placement are considered, SAIL with tirofiban, either intra-arterial or IV, seems to safely induce sustained recanalization, offering a potential alternative to definitive angioplasty and stent placement.

Abstract
OBJECTIVE Complications or serious adverse events (SAEs) are common in the treatment of patients with large vessel occlusion stroke. There has been limited study of the impact of SAEs for patients after endovascular thrombectomy (EVT). The goal of this study was to characterize the rates and clinical impact of SAEs following EVT. METHODS A post hoc analysis was performed using pooled databases of the "DEVT" and "RESCUE BT" trials. SAEs were designated as symptomatic intracranial hemorrhage, brain herniation or craniectomy, respiratory failure, circulatory failure, pneumonia, deep venous thrombosis, and systemic bleeding. The primary endpoint was functional independence (modified Rankin scale score 0-2 within 90 days). Logistic regression analysis was used to determine the predictors and associations between SAEs and outcomes. RESULTS Of 1,182 enrolled patients, 402 (34%) had a procedural complication and 745 (63%) had 1,404 SAE occurrences with 4.65% in-hospital mortality. The three most frequent SAEs were pneumonia (620, 52.5%), systemic bleeding (174, 14.7%), and respiratory failure (173, 14.6%). Pneumonia, systemic bleeding, or deep venous thrombosis was less life-threatening. Patients with advanced age (adjusted odds ratio, 1.28 [95% confidence interval, 1.14-1.43]), higher NIHSS (1.09 [1.06-1.11]), occlusion site (middle cerebral artery-M1 vs. internal carotid artery [ICA]: 0.75 [0.53-1.04]; M2 vs. ICA: 1.30 [0.80-2.12]), longer procedure time (1.01 [1.00-1.01]), and unsuccessful vessel recanalization (1.79 [1.06-2.94]) were more likely to experience SAEs. Compared with no SAE, patients with SAEs had lower odds of functional independence (0.46 [0.40-0.54]). CONCLUSIONS Overall, SAEs diagnosed following thrombectomy in patients with stroke were common (more than 60%) and associated with functional dependence. Patients with advanced age, higher NIHSS, longer procedure time, and failed recanalization were more likely to experience SAEs. There was no statistical difference in the risk of SAEs among patients with M1 and M2 occluded compared with those ICA occluded. An understanding of the prevalence and predictors of SAEs could alert clinicians to the estimated risk of an SAE for a patient after EVT.

Clin Neurol Neurosurg 2024; 243:108330. [PMID: 38936178 DOI: 10.1016/j.clineuro.2024.108330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 04/22/2024] [Accepted: 05/11/2024] [Indexed: 06/29/2024]
Abstract
OBJECT The use of endovascular therapy (EVT) has become a widespread strategy for the clinical management of acute ischemic stroke (AIS). However, the combination of arterial injection of tirofiban with EVT for AIS continues to be a subject of controversy. This meta-analysis was conducted to assess the safety and efficacy of this treatment approach. METHODS Relevant studies were identified through a systematic literature search in Pubmed, EMBASE, Web of Science, and Cochrane Library databases, covering articles published from January 2010 to January 2023. The efficacy outcomes included favorable functional outcomes, recanalization rates, and safety outcomes including mortality and symptomatic intracranial hemorrhage (sICH). RESULTS The meta-analysis consisted of data from 13 studies, which included 1 randomized controlled trial (RCT), 7 prospective cohort studies, and 5 retrospective cohort studies, encompassing a total of 3477 patients. The study results indicate that the intra-arterial (IA) tirofiban+EVT for AIS is associated with significant improvements in favorable functional outcomes (OR, 1.21; 95%CI, 1.05-1.40; P = 0.009) and recanalization rate (OR, 1.33; 95%CI, 1.06-1.65; P = 0.01), as well as significant reductions in mortality rates (OR, 0.65; 95%CI, 0.53-0.79; P = 0.0001). Subgroup analysis revealed that administering a maintenance dose of intravenous (IV) tirofiban post-EVT was significantly associated with improved functional outcomes and reduced mortality in patients. In addition, there was no increase in the incidence of sICH (OR, 0.92; 95%CI, 0.71-1.20; P = 0.54). CONCLUSION The administration of Intra-arterial tirofiban combined with EVT is an effective and safe treatment strategy for AIS, and postoperative maintenance doses of intravenous tirofiban may be more effective than IA only.

Abstract
BACKGROUND Valvular diseases are widely recognized as important etiologies for large vessel occlusion stroke (LVO) but their impact on outcomes among patients with LVO receiving endovascular treatment (EVT) are less well delineated. METHODS This study was a post hoc exploratory analysis of the RESCUE-BT trial, DEVT trial and BASILAR prospective registry. Outcome measures included the modified Rankin Scale (mRS) score at 90 days, symptomatic intracranial hemorrhage, and post-stroke early acute heart failure (EAHF). Chronic significant mitral regurgitation (csMR) was defined as a long-existing mitral regurgitation (MR) with moderate-to-severe MR grade examined by the transthoracic echocardiography. Adjusted odds ratio (aOR) and 95% confidence interval (CI) were obtained by logistic regression models. RESULTS Among 2011 patients in these three studies, 837 individuals receiving EVT with available information for valvular status were included in this study. In all categories of chronic valvular disorders, only csMR was related to very poor outcomes (mRS 5-6, aOR 2.76 (95% CI 1.59 to 4.78), P<0.001). CsMR (aOR 7.65 (95% CI 4.33 to 13.49), P<0.001) was an independent predictor of post-stroke EAHF. Mediation analysis showed that csMR increased EAHF instead of reocclusion events or venous thrombosis mediated its effects on functional outcome (49.50% (95% CI 24.83% to 90.00%)). Identical results of csMR on clinical outcomes and post-stroke EAHF were detected in novel cohorts constructed by propensity score matching and sensitivity analysis. CONCLUSION Our study demonstrated that csMR was a mediator of heart-brain interaction associated with poor outcomes of LVO after EVT by increasing the frequency of post-stroke EAHF. Replication of these findings in a larger cohort is warranted.

Abstract
OBJECTIVE We performed a post hoc exploratory analysis of Remote Ischemic Conditioning for Acute Moderate Ischemic Stroke (RICAMIS) to determine whether hypertension history and baseline systolic blood pressure (SBP) affect the efficacy of remote ischemic conditioning (RIC). METHODS Based on the full analysis set of RICAMIS, patients were divided into hypertension versus non-hypertension group, or <140 mmHg versus ≥140 mmHg group. Each group was further subdivided into RIC and control subgroups. The primary outcome was modified Rankin Scale (mRS) 0-1 at 90 days. Efficacy of RIC was compared among patients with hypertension versus nonhypertension history and SBP of <140 mmHg versus ≥140 mmHg. Furthermore, the interaction effect of treatment with hypertension and SBP was assessed. RESULTS Compared with control group, RIC produced a significantly higher proportion of patients with excellent functional outcome in the nonhypertension group (RIC vs. control: 65.7% vs. 57.0%, OR 1.45, 95% CI 1.06-1.98; p = 0.02), but no significant difference was observed in the hypertension group (RIC vs. control: 69.1% vs. 65.2%, p = 0.17). Similar results were observed in SBP ≥140 mmHg group (RIC vs. control: 68.0% vs. 61.2%, p = 0.009) and SBP <140 mmHg group (RIC vs. control: 65.6% vs. 64.7%, p = 0.77). No interaction effect of RIC on primary outcome was identified. INTERPRETATION Hypertension and baseline SBP did not affect the neuroprotective effect of RIC, but they were associated with higher probability of excellent functional outcome in patients with acute moderate ischemic stroke who received RIC treatment.

Abstract
OBJECTIVE The aim of this study was to investigate the factors influencing good outcomes in patients receiving only intravenous tirofiban with endovascular thrombectomy for large vessel occlusion stroke. METHODS Post hoc exploratory analysis using the RESCUE BT trial identified consecutive patients who received intravenous tirofiban with endovascular thrombectomy for large vessel occlusion stroke in 55 comprehensive stroke centers from October 2018 to January 2022 in China. RESULTS A total of 521 patients received intravenous tirofiban, 253 of whom achieved a good 90-day outcome (modified Rankin Scale [mRS] 0-2). Younger age (adjusted odds ratio [aOR]: 0.965, 95% confidence interval [CI]: 0.947-0.982; p < 0.001), lower serum glucose (aOR: 0.865, 95%CI: 0.807-0.928; p < 0.001), lower baseline National Institutes of Health Stroke Scale (NIHSS) score (aOR: 0.907, 95%CI: 0.869-0.947; p < 0.001), fewer total passes (aOR: 0.791, 95%CI: 0.665-0.939; p = 0.008), shorter punctures to recanalization time (aOR: 0.995, 95%CI:0.991-0.999; p = 0.017), and modified Thrombolysis in Cerebral Infarction (mTICI) score 2b to 3 (aOR: 8.330, 95%CI: 2.705-25.653; p < 0.001) were independent predictors of good outcomes after intravenous tirofiban with endovascular thrombectomy for large vessel occlusion stroke. CONCLUSION Younger age, lower serum glucose level, lower baseline NIHSS score, fewer total passes, shorter punctures to recanalization time, and mTICI scores of 2b to 3 were independent predictors of good outcomes after intravenous tirofiban with endovascular thrombectomy for large vessel occlusion stroke.

Abstract
BACKGROUND Several antithrombotic treatments during emergent carotid artery stenting (eCAS) have been proposed, but an appropriate protocol to balance risk-benefit is not well known. OBJECTIVE To investigate the efficacy and safety of tirofiban compared with aspirin in patients with acute ischemic stroke undergoing eCAS. METHODS We conducted a retrospective single-center study of the prospective ARTISTA Registry, including patients with atherosclerotic internal carotid artery occlusion treated with eCAS. Two groups, according to antiplatelet drug, were studied: aspirin (250-500 mg single-dose) versus tirofiban (500 μg bolus+200 μg/h). Primary outcomes were the rate of in-stent thrombosis and symptomatic intracranial hemorrhage (sICH) within the first 24 hours. RESULTS During the period 2019-2023, 181 patients were included, 103 received aspirin, 78 tirofiban; 149 (82.3%) had tandem lesions. The primary efficacy outcome occurred in 9 (9.4%) in the aspirin group, as compared with 1 (1.3%) in the tirofiban group (adjusted odds ratio (aOR)=0.11, 95% CI 0.01 to 0.98; P=0.048). The primary safety outcome was detected in 12 (11.7%) in the aspirin group, as compared with 2 (2.6%) in the tirofiban group (aOR=0.16, 95% CI 0.03 to 0.87; P=0.034). The tirofiban group presented a lower risk of parenchymal hemorrhage (18 (17.4%) vs 4 (5.2%), aOR=0.27, 95% CI 0.09 to 0.88; P=0.029) and an increased rate of excellent recanalization (expanded Treatment in Cerebral Infarction (eTICI) 2c-3) (50 (48.5%) vs 54 (69.2%); aOR=2.15, 95% CI 1.12 to 4.13; P=0.02). There were no differences in functional outcomes or mortality at 3 months. CONCLUSIONS Periprocedural antithrombotic therapy with tirofiban was associated with a lower risk of in-stent thrombosis and sICH at 24 hours from eCAS compared with aspirin. Prospective randomized clinical trials are needed to confirm our results.

Early administration of tirofiban after IVT may improve patient outcomes. OBJECTIVE To evaluate the efficacy and safety of early tirofiban administration after intravenous tenecteplase in patients with acute ischemic stroke. METHODS AND DESIGN The ADVENT trial is a multicenter, randomized, parallel-controlled, double-blind clinical trial. A total of 1084 patients undergoing IVT without subsequent endovascular treatment will be recruited from multiple hospitals in China. Subjects will be randomized in a 1:1 ratio to receive tirofiban or placebo, which will be infused within 6 h after IVT until 24 h after IVT, at 0.4 μg/kg/min for 30 min and then at 0.1 μg/kg/min. The primary efficacy outcome is the proportion of patients with excellent functional outcomes (modified Rankin Scale (mRS) ⩽ 1) at 90 days. Secondary outcomes include the proportion of patients with favorable functional outcomes (mRS ⩽ 2) at 90 days and neurological functional assessments evaluated during hospitalization. Symptomatic intracranial hemorrhage will be the primary safety outcome. Mortality and other adverse events will be recorded. DISCUSSION This pivotal trial will provide important data on the early administration of antiplatelet therapy after IVT and may promote progress in treatment standards.

The impacts of venous outflow profiles on outcomes among large vessel occlusion patients receiving endovascular treatment in the late window. Eur Radiol 2024:10.1007/s00330-024-10742-3. [PMID: 38724767 DOI: 10.1007/s00330-024-10742-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 03/17/2024] [Accepted: 03/21/2024] [Indexed: 05/30/2024]
Abstract
OBJECTIVES To investigate the association between venous outflow (VO) profiles and outcomes among acute ischemic stroke caused by anterior circulation large vessel occlusion (AIS-LVO) patients who had undergone endovascular treatment (EVT) in the late window of 6-24 h from stroke onset. METHODS This was a post-hoc analysis of our preceding RESCUE-BT trial, with findings validated in an external cohort. Baseline computed tomographic angiography (CTA) was performed to assess VO using the Cortical Vein Opacification Score (COVES). The primary clinical outcome was functional independence at 90 days (modified Rankin Scale score of 0-2). The adjusted odd ratio (aOR) and confidence interval (CI) were obtained from multivariable logistic regressions. RESULTS A total of 440 patients were included in the present study. After identifying the cutoff of COVES by marginal effects approach, enrolled patients were divided into the favorable VO group (COVES 4-6) and the poor VO (COVES 0-3) group. Multivariable logistic regression analysis showed that favorable VO (aOR 2.25; 95% CI 1.31-3.86; p = 0.003) was associated with functional independence. Similar results were detected in the external validation cohort. Among those with poor arterial collateralization, favorable VO was still an independent predictor of functional independence (aOR 2.09; 95% CI 1.06-4.10; p = 0.032). CONCLUSION The robust VO profile indicated by COVES 4-6 could promote the frequency of functional independence among AIS-LVO patients receiving EVT in the late window, and the prognostic value of VO was independent of the arterial collateral status. CLINICAL RELEVANCE STATEMENT The robust venous outflow profile was a valid predictor for functional independence among AIS-LVO patients receiving EVT in the late window (6-24 h) and the predictive role of venous outflow did not rely on the status of arterial collateral circulation.

Abstract
BACKGROUND We performed a review of acute stroke trials to determine features associated with premature termination of trial enrollment, defined by the authors as not meeting preplanned sample size. METHODS AND RESULTS MEDLINE was searched for randomized clinical stroke trials published in 9 major clinical journals between 2013 and 2022. We included randomized clinical trials that were phase 2 or 3 with a preplanned sample size ≥100 and a time-to-treatment within 24 hours of onset for transient ischemic attack, ischemic stroke, or intracerebral hemorrhage. Data were abstracted on trial features including trial design, inclusion criteria, imaging, location and number of sites, masking, treatment complexity, control group (standard therapy, placebo), industry involvement, and preplanned stopping rules (futility and efficacy). Least absolute shrinkage and selection operator regression was used to select the most important factors associated with premature termination; then, a multivariable logistic regression was fit including only the least absolute shrinkage and selection operator selected variables. Of 1475 studies assessed, 98 trials met eligibility criteria. Forty-five (46%) trials were prematurely terminated, of which 27% were stopped for benefit/efficacy, 20% for lack of money/slow enrollment, 18% for futility, 16% for newly available evidence, 17% for other reasons, and 4% due to harm. Complex trials (adjusted odds ratio [aOR], 2.76 [95% CI, 1.13-7.49]), presence of a futility rule (aOR, 4.43 [95% CI, 1.62-17.91]), and exclusion of prestroke dependency (none/slight disability only; aOR, 2.19 [95% CI, 0.84-6.72] versus dependency allowed) were identified as the strongest predictors. CONCLUSIONS Nearly half of acute stroke trials were terminated prematurely. Broadening inclusion criteria and simplifying trial design may decrease the likelihood of unplanned termination, whereas planned futility analyses may appropriately terminate trials early, saving money and resources.

Decompressive craniectomy for patients with malignant infarction of the middle cerebral artery: A pooled analysis of two randomized controlled trials. J Stroke Cerebrovasc Dis 2024; 33:107719. [PMID: 38604351 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 04/06/2024] [Accepted: 04/08/2024] [Indexed: 04/13/2024] Open
Abstract
BACKGROUND Decompressive craniectomy (DC) reduces mortality without increasing the risk of very severe disability among patients with life-threatening massive cerebral infarction. However, its efficacy was demonstrated before the era of endovascular thrombectomy trials. It remains uncertain whether DC improves the prognosis of patients with malignant middle cerebral artery (MCA) infarction receiving endovascular therapy. METHODS We pooled data from two trials (DEVT and RESCUE BT studies in China) and patients with malignant MCA infarction were included to assess outcomes and heterogeneity of DC therapy effect. Patients with herniation were dichotomized into DC and conservative groups according to their treatment strategy. The primary outcome was the rate of mortality at 90 days. Secondary outcomes included disability level at 90 days as measured by the modified Rankin Scale score (mRS) and quality-of-life score. The associations of DC with clinical outcomes were performed using multivariable logistic regression. RESULTS Of 98 patients with herniation, 37 received DC surgery and 61 received conservative treatment. The median (interquartile range) was 70 (62-76) years and 40.8% of the patients were women. The mortality rate at 90 days was 59.5% in the DC group compared with 85.2% in the conservative group (adjusted odds ratio, 0.31 [95% confidence interval (CI), 0.10-0.94]; P=0.04). There were 21.6% of patients in the DC group and 6.6% in the conservative group who had a mRS score of 4 (moderately severe disability); and 10.8% and 4.9%, respectively, had a score of 5 (severe disability). The quality-of-life score was higher in the DC group (0.00 [0.00-0.14] vs 0.00 [0.00-0.00], P=0.004), but DC treatment was not associated with better quality-of-life score in multivariable analyses (adjusted β Coefficient, 0.02 [95% CI, -0.08-0.11]; p=0.75). CONCLUSIONS DC was associated with decreased mortality among patients with malignant MCA infarction who received endovascular therapy. The majority of survivors remained moderately severe disability and required improvement on quality of life. CLINICAL TRIAL REGISTRATION The DEVT trial: http://www.chictr.org.

Front Neurol 2024; 15:1286079. [PMID: 38633532 PMCID: PMC11021731 DOI: 10.3389/fneur.2024.1286079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 02/26/2024] [Indexed: 04/19/2024] Open
Abstract
Introduction Tirofiban is a non-peptide selective glycoprotein IIb/IIIa receptor inhibitor with a short half-life. The research assesses the efficacy and safety of continuous intravenous tirofiban in patients with acute ischemic stroke (AIS) undergoing endovascular therapy (ET). Methods A systematic search of Pubmed, Embase, Web of Science, and Cochrane Library databases is conducted from inception until January 26, 2024. Eligible studies are included based on predefined selection criteria. Efficacy outcomes (favorable functional outcome and excellent functional outcome) and safety outcomes (symptomatic intracranial hemorrhage [sICH], any intracranial hemorrhage [ICH], and 90-day mortality) are calculated using odds ratios (OR) and 95% confidence intervals (CI). Results A total of 4,329 patients from 15 studies are included in the analysis. The results indicate a significant trend toward favorable functional outcomes in the tirofiban group (OR, 1.24; 95% CI, 1.09-1.42; p = 0.001). In terms of safety outcomes, tirofiban does not increase the risk of sICH (OR, 0.90; 95% CI, 0.71-1.13; p = 0.35) or any ICH (OR, 0.97; 95% CI, 0.70-1.34; p = 0.85), but it significantly decreases 90-day mortality (OR, 0.75; 95% CI, 0.64-0.88; p = 0.0006). A subgroup analysis suggests that continuous intravenous tirofiban demonstrates better efficacy (OR, 1.24; 95% CI, 1.09-1.42; p = 0.001) for patients with AIS undergoing rescue ET with even better results when used in combination with intra-arterial and intravenous administration (OR, 1.25; 95% CI, 1.07-1.451; p = 0.005). Conclusion Continuous intravenous tirofiban is effective and safe for patients with AIS undergoing rescue ET, particularly when combined with intra-arterial tirofiban.

Intravenous Thrombolysis before Complete Angiographic Reperfusion: Beyond Angiographic Assessment to Target Microvascular Obstruction? Ann Neurol 2024; 95:762-773. [PMID: 38148607 DOI: 10.1002/ana.26867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 12/19/2023] [Accepted: 12/20/2023] [Indexed: 12/28/2023]
Abstract
OBJECTIVE Recent data have suggested that ineffective tissue reperfusion despite successful angiographic reperfusion was partly responsible for unfavorable outcomes after endovascular therapy (EVT) and might be modulated by intravenous thrombolysis (IVT) use before EVT. To specifically decipher the effect played by IVT before EVT, we compared the clinical and safety outcomes of patients who experienced a complete reperfusion at the end of EVT according to IVT use before EVT. METHODS The Endovascular Treatment in Ischemic Stroke (ETIS) registry is an ongoing, prospective, observational study at 21 centers that perform EVT in France. Patients were included if they had an anterior large vessel occlusion of the intracranial internal carotid artery or middle cerebral artery (M1/M2 segments) and complete reperfusion (expanded Thrombolysis in Cerebral Infarction score = 3) with EVT within 6 hours, between January 2015 and December 2021. The cohort was divided into two groups according to IVT use before EVT, and propensity score matching (PSM) was used to balance the two groups. Primary outcome was the shift in the degree of disability as measured by the modified Rankin Scale (mRS) at 90 days. Secondary outcomes included favorable outcome (mRS 0-2) at 90 days. Safety outcomes included symptomatic intracranial hemorrhage and 90-day mortality. Outcomes were estimated with multivariate logistic models adjusted for age, National Institutes of Health Stroke Scale, Alberta Stroke Program Early CT Score, and time from symptom onset to puncture. RESULTS Among 5,429 patients included in the ETIS registry, 1,093 were included in the study, including 651 patients with complete recanalization treated with IVT before EVT. After PSM, 488 patients treated with IVT before EVT were compared to 337 patients without IVT. In the matched cohort analysis, the IVT+EVT group had a favorable shift in the overall mRS score distribution (adjusted odds ratio [aOR] = 1.41, 95% confidence interval [CI] = 1.04-1.91, p = 0.023) and higher rates of favorable outcome (61.1% vs 48.7%, aOR = 1.49, 95% CI = 1.02-2.20, p = 0.041) at 90 days compared with the EVT alone group. Rates of symptomatic intracerebral hemorrhage were comparable between both groups (6.0% vs 4.3%, aOR = 1.16, 95% CI = 0.53-2.54, p = 0.709). INTERPRETATION In clinical practice, even after complete angiographic reperfusion by EVT, prior IVT use improves clinical outcomes of patients without increasing bleeding risk.

Abstract
BACKGROUND Approximately half of patients who achieve successful reperfusion do not achieve functional independence. The present study sought to investigate the clinical outcomes and safety of intraarterial or intravenous tirofiban as adjunct therapy in patients with acute basilar artery occlusion who had achieved successful recanalization with endovascular treatment. METHODS AND RESULTS In the national, prospective BASILAR (Endovascular Treatment for Acute Basilar Artery Occlusion Study) registry, 458 patients who met inclusion criteria were divided into 3 groups based on tirofiban administration (no tirofiban, n=262; intravenous tirofiban, n=101; intraarterial+intravenous tirofiban, n=95). Their clinical outcomes were compared with 90-day modified Rankin Scale scores. Adjusted odds ratios (aORs) and 95% CIs were obtained by logistic regression models and propensity score matching. Safety outcomes included any intracranial hemorrhage (ICH), symptomatic ICH, and mortality. Among 458 included patients, 184 (40.2%) achieved a favorable outcome (modified Rankin Scale score 0-3). There were no differences between the intravenous tirofiban group and the no tirofiban group in terms of safety and clinical outcomes (all P>0.05). Compared with the no tirofiban group, the intraarterial+intravenous tirofiban group had higher odds of 90-day modified Rankin Scale score 0 to 3 (aOR, 2.44 [95% CI, 1.30-4.64], P=0.006) and lower 3-month mortality (aOR, 0.38 [95% CI, 0.19-0.71], P=0.002) without an increase in any ICH (aOR, 0.34 [95% CI, 0.09-1.01], P=0.07) or symptomatic ICH (aOR, 0.23 [95% CI, 0.03-0.90], P=0.05). Similar results of intraarterial+intravenous tirofiban on improving clinical outcomes were detected in novel cohorts constructed by propensity score matching. CONCLUSIONS Intraarterial+intravenous rather than intravenous tirofiban improved clinical outcomes without increasing the frequency of symptomatic ICH among patients with basilar artery occlusion after successful endovascular treatment. Further studies are needed to delineate the roles of intraarterial+intravenous tirofiban in patients with basilar artery occlusion receiving endovascular treatment.

Abstract
BACKGROUND This study sought to scrutinize the clinical outcomes associated with first-pass mechanical thrombectomy strategies in the management of intracranial atherosclerosis (ICAS)-related large vessel occlusion (LVO). METHODS Within this post-hoc analysis of the The Endovascular Treatment With vs Without Tirofiban for Patients with Large Vessel Occlusion Stroke (RESCUE BT) trial, we compared data pertaining to patients with ICAS-LVO situated in the anterior circulation who underwent initial therapeutic interventions utilizing either aspiration thrombectomy or stent-retriever thrombectomy. The analysis encompassed the assessment of intraprocedural recanalization, rescue procedures involving balloon angioplasty or stenting, 48-hour reocclusion rates, occurrences of cerebral hemorrhagic complications, and 90-day Modified Rankin Scale scores. RESULTS Among the 948 patients encompassed in the RESCUE BT trial, a total of 230 patients with ICAS-LVO in the anterior circulation were enrolled in the study. Of these, 111 underwent aspiration thrombectomy as the first-pass therapy, while 119 patients underwent stent-retriever thrombectomy as the initial intervention. The difference in first pass recanalization rates between aspiration thrombectomy and stent-retriever thrombectomy was not statistically significant (17.1% vs. 14.3%, P = 0.555), and mechanical thrombectomy success rates (90.1% vs. 90.8%, P = 0.864), the use of balloon angioplasty or stenting for rescue therapy (54.6% vs. 45.9%, P = 0.189; 23.4% vs. 25.2%, P = 0.752), and favorable 90-day Modified Rankin Scale outcomes (53.2% vs. 40.3%, P = 0.051) showed no statistically significant differences. CONCLUSIONS Both aspiration thrombectomy and stent-retriever thrombectomy can be considered as primary therapeutic options for patients presenting with ICAS-LVO in the anterior circulation.

Effects of tirofiban on large vessel occlusion stroke are modified by etiology and renal function. Ann Clin Transl Neurol 2024; 11:618-628. [PMID: 38156359 DOI: 10.1002/acn3.51982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 12/05/2023] [Accepted: 12/16/2023] [Indexed: 12/30/2023] Open
Abstract
OBJECTIVE Renal function can modify the outcomes of large vessel occlusion (LVO) stroke across stroke etiologies in disparate degrees. The presence of renal function deficit can also impair the pharmacokinetics of tirofiban. Hence, this study aimed to investigate the roles of renal function in determining efficacy and safety of intravenous tirofiban before endovascular treatment (EVT) for acute ischemic stroke patients with large vessel occlusion (LVO). METHODS This study was a post hoc exploratory analysis of the RESCUE-BT trial. The primary outcome was the proportion of patients achieving functional independence (modified Rankin scale 0-2) at 90 days, and the primary safety outcome was the rate of symptomatic intracranial hemorrhage (sICH). RESULTS Among 908 individuals with available serum creatinine, decreased estimated glomerular filtration rate (eGFR) status was noted more commonly in patients with cardioembolic stroke (CE), while large artery atherosclerosis (LAA) was predominant in patients with normal renal function. In LAA with normal renal function, tirofiban was associated with higher rates of functional independence at 90 days (41.67% vs 59.80%, p = 0.003). However, for LVO patients with renal dysfunction, tirofiban did not improve functional outcomes for any of the etiologies (LAA, p = 0.876; CE, p = 0.662; others, p = 0.894) and significantly increased the risk of sICH among non-LAA patients (p = 0.020). Mediation analysis showed tirofiban reduced thrombectomy passes (12.27%) and drug/placebo to recanalization time (14.25%) mediated its effects on functional independence. CONCLUSION This present study demonstrated the importance of evaluating renal function before administering intravenous tirofiban among patients with LVO who are planned to undergo EVT.

Balloon angioplasty as first-choice recanalization strategy for intracranial atherosclerosis-related emergent large vessel occlusion with small clot burden. Neuroradiology 2024; 66:399-407.

Abstract
PURPOSE The optimal primary recanalization strategy for intracranial atherosclerosis-related emergent large vessel occlusion (ICAS-ELVO) remains controversial. We aimed to explore the safety and efficacy of balloon angioplasty as the first-choice recanalization strategy for ICAS-ELVO with small clot burden. METHODS Consecutive ICAS-ELVO patients presenting with microcatheter "first-pass effect" during endovascular treatment (EVT) were retrospectively analyzed. Patients were divided into preferred balloon angioplasty (PBA) and preferred mechanical thrombectomy (PMT) groups based on the first-choice recanalization strategy. The reperfusion and clinical outcomes between the two groups were compared. RESULTS Seventy-six patients with ICAS-ELVO involving the microcatheter "first-pass effect" during EVT were enrolled. Compared with patients in the PMT group, those in the PBA group were associated with (i) a higher rate of first-pass recanalization (54.0% vs. 28.9%, p = .010) and complete reperfusion (expanded thrombolysis in cerebral ischemia ≥ 2c; 76.0% vs. 53.8%, p = .049), (ii) shorter puncture-to-recanalization time (49.5 min vs. 89.0 min, p < .001), (iii) lower operation costs (¥48,499.5 vs. ¥ 99,086.0, p < .001), and (iv) better 90-day functional outcomes (modified Rankin scale:0-1; 44.0% vs. 19.2%, p = .032). Logistic regression analysis revealed that balloon angioplasty as the first-choice recanalization strategy was an independent predictor of 90-day excellent functional outcomes for ICAS-ELVO patients with microcatheter "first-pass effect" (adjusted odds ratio = 6.01, 95% confidence interval: 1.15-31.51, p = .034). CONCLUSION Direct balloon angioplasty potentially improves 90-day functional outcomes for ICAS-ELVO patients with small clot burden, and may be a more appropriate first-choice recanalization strategy than mechanical thrombectomy for these patients.

Abstract
Background and purpose Adjunctive tirofiban administration in patients undergoing endovascular treatment (EVT) for acute large vessel occlusion (LVO) has been investigated in several studies. However, the findings are conflict. This study aimed to compare the effect of different administration pathways of tirofiban on patients undergoing EVT for acute LVO with intracranial atherosclerotic disease (ICAD). Methods Patients were selected from the ANGEL-ACT Registry (Endovascular Treatment Key Technique and Emergency Workflow Improvement of Acute Ischemic Stroke: A Prospective Multicenter Registry Study) and divided into four groups: intra-arterial (IA), intravenous (IV), and intra-arterial plus intravenous (IA+IV) and non-tirofiban. The primary outcome was 90-day ordinal modified Rankin Scale (mRS) score, and the secondary outcomes included the rates of mRS 0-1, 0-2, and 0-3 at 90-day, successful recanalization. The safety outcomes were symptomatic intracranial hemorrhage (sICH) and other safety endpoints. The multivariable logistic regression models adjusting for potential baseline confounders were performed to compare the outcomes. A propensity score matching (PSM) with a 1:1:1:1 ratio was conducted among four groups, and the outcomes were then compared in the post-matched population. Results A total of 502 patients were included, 80 of which were in the IA-tirofiban group, 73 in IV-tirofiban, 181 in (IA+IV)-tirofiban group, and 168 in the non-tirofiban group. The median (IQR) 90-day mRS score in the four groups of IA, IV, IA+IV, and non-tirofiban was, respectively 3(0-5) vs. 1(0-4) vs. 1(0-4) vs. 3(0-5). The adjusted common odds ratio (OR) for 90-day ordinal modified Rankin Scale distribution with IA-tirofiban vs. non-tirofiban was 0.77 (95% CI, 0.45-1.30, P = 0.330), with IV-tirofiban vs. non-tirofiban was 1.36 (95% CI, 0.78-2.36, P = 0.276), and with (IA+IV)-tirofiban vs. non-tirofiban was 1.03 (95% CI, 0.64-1.64, P = 0.912). The adjusted OR for mRS 0-1 and mRS 0-2 at 90-day with IA-tirofiban vs. non-tirofiban was, respectively 0.51 (95% CI, 0.27-0.98, P = 0.042) and 0.50 (95% CI, 0.26-0.94, P = 0.033). The other outcomes of each group were similar with non-tirofiban group, all P was >0.05. After PSM, the common odds ratio (OR) for 90-day ordinal modified Rankin Scale distribution with IA-tirofiban vs. non-tirofiban was 0.41 (95% CI, 0.18-0.94, P = 0.036), and the OR for mRS 0-1 and mRS 0-2 at 90-day with IA-tirofiban vs. non-tirofiban was, respectively 0.28 (95% CI, 0.11-0.74, P = 0.011) and 0.25 (95% CI, 0.09-0.67, P = 0.006). Conclusions Intra-arterial administration of tirofiban was associated with worse outcome than non-tirofiban, which suggested that intra-arterial tirofiban had a harmful effect on patients undergoing EVT for ICAD-LVO.

Neurocrit Care 2024; 40:196-204. [PMID: 38148437 DOI: 10.1007/s12028-023-01900-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 11/22/2023] [Indexed: 12/28/2023]
Abstract
BACKGROUND Malignant brain edema (MBE) is a life-threatening complication that can occur after mechanical thrombectomy (MT) for acute ischemic stroke. The hypoperfusion intensity ratio (HIR) reflects the tissue-level perfusion status within the ischemic territory. This study investigated the association between HIR and MBE occurrence after MT in patients with anterior circulation large artery occlusion. METHODS We conducted a retrospective cohort study of patients who received MT at a comprehensive stroke center from February 2020 to June 2022. Using computed tomography perfusion, the HIR was derived from the ratio of tissue volume with a time to maximum (Tmax) > 10 s to that with a Tmax > 6 s. We dichotomized patients based on the occurrence of MBE following MT. The primary outcome, assessed using a multivariable logistic regression model, was the MBE occurrence post MT. The secondary outcome focused on favorable outcomes, defined as achieving a modified Rankin Scale score of 0-2 at 90 days. RESULTS Of the 603 included patients, 90 (14.9%) developed MBE after MT. The median HIR exhibited a significantly higher value in the MBE group compared with the non-MBE group (0.5 vs. 0.3; P < 0.001). Multivariable logistic regression analysis indicated that a higher HIR (adjusted odds ratio [aOR] 8.98; 95% confidence interval [CI] 2.85-28.25; P < 0.001), baseline large infarction (Alberta Stroke Program Early Computed Tomography Score < 6; aOR 1.77; 95% CI 1.04-3.01; P = 0.035), internal carotid artery occlusion (aOR 1.80; 95% CI 1.07-3.01; P = 0.028), and unsuccessful recanalization (aOR 8.45; 95% CI 4.75-15.03; P < 0.001) were independently associated with MBE post MT. Among those with successful recanalization, a higher HIR (P = 0.017) and baseline large infarction (P = 0.032) remained as predictors of MBE occurrence. Furthermore, a higher HIR (P = 0.001) and the occurrence of MBE (P < 0.001) both correlated with reduced odds of achieving favorable outcomes. CONCLUSIONS The presence of a higher HIR on pretreatment perfusion imaging serves as a robust predictor for MBE occurrence after MT, irrespective of successful recanalization.

Abstract
PURPOSE The purpose of the study was to evaluate the efficacy and safety of tirofiban use in endovascular thrombectomy for intravenous thrombolysis applicable patients of large vessel occlusion stroke with data from Direct-MT trial. MATERIALS AND METHODS Direct-MT was the first randomized controlled trial to prove the non-inferiority of thrombectomy alone to bridging therapy (intravenous thrombolysis before thrombectomy) for large vessel occlusion stroke. Patients who underwent endovascular procedure were included and divided into thrombectomy-alone group and bridging therapy group. The effect of tirofiban use on 90 days MRS distribution, MRS 0-2 and mortality, successful reperfusion, the ASPECTS and outcome lesion volume of index stroke, re-occlusion of the treated vessel, futile recanalization and safety outcomes were further evaluated in both groups after adjustment for relevant confounding factors. The interaction between tirofiban and rt-PA was also assessed. RESULTS Of 639 patients included in this analysis, 180 patients underwent thrombectomy with tirofiban use (28.2%). Patients with tirofiban use had lower percentage of bridging therapy (41.1% vs 54.3%, P = 0.003), higher proportion of large artery atherosclerosis (P < 0.001) and more emergent stenting (30.56% vs 6.97%, P < 0.001). After adjustment for confounding factors, the 90-day modified Rankin Scale distribution, successful final recanalization rate, outcome lesion volume of index stroke on CT and intracranial hemorrhage risk showed no difference after tirofiban use in thrombectomy-alone group and in bridging therapy group. No interaction effect between tirofiban and rt-PA was detected. CONCLUSION Based on data from Direct-MT trial, tirofiban is a safe medication for intravenous thrombolysis applicable patients with large vessel occlusion stroke undergoing thrombectomy.

Perioperative complications of arteriovenous tirofiban administration versus oral dual antiplatelet therapy for stent-assisted embolization treated aneurysmal subarachnoid hemorrhage: A retrospective, controlled cohort analysis. Brain Behav 2024; 14:e3439. [PMID: 38409912 PMCID: PMC10897354 DOI: 10.1002/brb3.3439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 01/29/2024] [Accepted: 02/02/2024] [Indexed: 02/28/2024] Open
Abstract
BACKGROUND Major perioperative complications of stent-assisted embolization treated for aneurysmal subarachnoid hemorrhage patients include the formation of thromboembolic events (TEs) and hemorrhagic events (HEs), for which antiplatelet protocols play a key role. METHODS We conducted a single-center retrospective analysis to compare the differences between arteriovenous tirofiban administration with traditional oral dual antiplatelet therapy (DAPT). A total of 417 consecutive patients were enrolled. General clinical characteristics, as well as the perioperative ischemic and hemorrhagic events, were retracted in digital documents. Logistic regression was conducted to identify both risk and protective factors of perioperative TEs and HEs. RESULTS Perioperative TEs occurred in 21 patients, with an overall perioperative TEs rate of approximately 5.04%; among these patients, the incidence of perioperative TEs in the tirofiban group was less than that in the DAPT group. Additionally, 66 patients developed perioperative HEs, with an incidence of approximately 15.83%; among these patients, the incidence of perioperative HEs was less than that in the DAPT group. No significant differences were seen between the two groups in terms of the mRS score at the time of discharge. CONCLUSION This study indicated that an improved perioperative antiplatelet drug tirofiban was an independent protective factor for perioperative TEs in stent-assisted embolization of ruptured intracranial aneurysms, but it did not impart an elevated risk of perioperative HEs and had no significant effects on the near-term prognosis of the patients.

Abstract
BACKGROUND Half of patients who achieve successful recanalization following endovascular thrombectomy (EVT) for acute ischemic stroke experience poor functional outcome. We aim to investigate whether the use of adjunctive intra-arterial antithrombotic therapy (AAT) during EVT is safe and efficacious compared with standard therapy (ST) of EVT with or without prior intravenous thrombolysis. METHODS Electronic databases were searched (PubMed/MEDLINE, Embase, Cochrane Library) from 2010 until October 2023. Data were pooled using a random-effects model and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Risk of bias was assessed using ROBINS-I and ROB-2. The primary outcome was functional independence (modified Rankin Scale (mRS) 0-2) at 3 months. Secondary outcomes were successful recanalization (modified Thrombolysis In Cerebral Infarction (TICI) 2b-3), symptomatic intracranial hemorrhage (sICH), and 90-day mortality. RESULTS 41 randomized and non-randomized studies met the eligibility criteria. Overall, 15 316 patients were included; 3296 patients were treated with AAT during EVT and 12 020 were treated with ST alone. Compared with ST, patients treated with AAT demonstrated higher odds of functional independence (46.5% AAT vs 42.6% ST; OR 1.22, 95% CI 1.07 to 1.40, P=0.004, I2=48%) and a lower likelihood of 90-day mortality (OR 0.71, 95% CI 0.61 to 0.83, P<0.0001, I2=20%). The rates of sICH (OR 1.00, 95% CI 0.82 to 1.22,P=0.97, I2=13%) and successful recanalization (OR 1.09, 95% CI 0.84 to 1.42, P=0.52, I2=76%) were not significantly different. CONCLUSION The use of AAT during EVT may improve functional outcomes and reduce mortality rates compared with ST alone, without an increased risk of sICH. These findings should be interpreted with caution pending the results from ongoing phase III trials to establish the efficacy and safety of AAT during EVT.

Abstract
BACKGROUND Intracranial atherosclerotic disease (ICAD) is a major cause of stroke with a high rate of re-occlusion following mechanical thrombectomy (MT). Among the available rescue options, glycoprotein IIb/IIIa inhibitors (GPI) have shown promise as a potential therapeutic strategy. This systematic review and meta-analysis examine studies exploring the use of glycoprotein inhibitors as a first-line treatment for refractory occlusion or high-grade stenosis following EVT in the setting of ICAD. METHODS A systematic review and meta-analysis were performed. Studies using GPI as the first-line rescue treatment (GPI-rt) after failed thrombectomy or in the setting with high-grade stenosis (>50%) were included. The primary outcome of interest was good clinical outcomes (defined as a modified Rankin Scale (mRS) score of 0-2 at 90 days). Secondary outcomes of interest were successful recanalization (TICI 2b-3), symptomatic intracranial hemorrhage (sICH), and mortality by 90 days. RESULTS Our study processed 2111 articles, which yielded eight relevant studies for review, four single and four double arm. These studies comprised 763 patients, divided into GPI-rt (535 patients) and non-GPI-rt (228 patients) cohorts. The GPI-rt group had higher rates of mRS ≤ 2 at 90 days (58.5% vs 38.9%, p = 0.002) and lower mortality rates (7.8% vs 17.5%, p = 0.04) compared to the non-GPI-rt cohort. mTICI 2b-3 rates and rates of sICH were not significantly different between the cohorts. CONCLUSIONS First line GPI-rt demonstrates significant clinical benefit and significantly lower mortality without a rise in rates of sICH. GPI are a potential first line rescue treatment of ICAD.

Abstract
BACKGROUND The modified Rankin Scale (mRS) score of ≤2 (functional independence) has been the most common primary endpoint of modern mechanical thrombectomy (MT) trials. However, unlike mRS 0-1, mRS score of 2 indicates disability. An important proportion of the mRS 2 patients are home dependent and report a significant decrease in their quality of life. PURPOSE To investigate excellent outcome (mRS 0-1) rates after MT. METHODS We systematically searched Ovid MEDLINE, Ovid EMBASE, Cochrane Central Register of Controlled Trials, Scopus, and Web of Science databases. Randomized controlled trials (RCTs) investigating the role of modern MT in acute ischemic stroke were screened. Posterior circulation and large-core infarct trials were excluded from the study. The data regarding excellent outcomes (mRS: 0-1), functional independence (mRS: 0-2), and reperfusion were collected. RESULTS Twenty-two RCTs comprising 5692 patients were included in the meta-analysis. The overall mRS 0-1 rate was 31.24% (95% CI = 26.95-36.2). The rate of successful reperfusion was 81.8% (95% CI = 77.93-85.86). MT achieved significantly higher rates of mRS 0-1 compared to standard care alone (OR = 2.04; 95% CI = 1.64-2.55; P-value < 0.001), with no heterogeneity detected among studies (I2= 0%; P-value = 0.52). The direct MT and MT plus intravenous thrombolytic treatment groups' excellent outcome rates were comparable (OR = 0.98; 95% CI = 0.82-1.18; P-value = 0.863). Also, aspiration and stent retriever thrombectomy techniques provided similar excellent outcome rates (OR = 0.76; 95% CI = 0.55-1.05; P-value = 0.141). CONCLUSIONS Our results prove the additional benefit of MT over standard care, using a stricter definition for favorable functional outcome. Nearly one-third of patients presenting with large artery occlusion and treated with MT had no disability at 90 days. While this is remarkable, our results also indicate that reperfusion alone is often not enough to prevent disability and underline the need for better neuroprotection strategies.

Abstract
BACKGROUND Ischemic stroke is the second leading cause of death worldwide. Endovascular thrombectomy (ET) has been shown to prevent disability in a proportion of patients. The use of tirofiban in patients undergoing ET after acute stroke has resulted in improved patient function and reduced mortality to some extent. In this systematic review and meta-analysis of the current period, an overview of the most recent studies on the potential efficacy of using tirofiban to help acute stroke patients improve function and reduce mortality was provided. METHODS In this meta-analysis, we explore the safety and efficacy of ET combined with tirofiban in patients with acute stroke. We searched the PubMed, EMBASE, Web of Science, and The Cochrane Library database from the construction of the library to the present relevant RCTs/non-RCTs. The following key words were used for finding relevant studies from the databases"tirofiban""thrombectomy"" Stroke"" balloon angioplasty""stenting". RESULTS Total of 14 trials with 4366 individuals enrolled were included in the Meta-analysis including 2732(62.6) who received ET alone and 1634(37.4 %) who received tirofiban plus ET. The primary outcome of 90-day functional independence (modified Rankin scale (mRS) score≤2) was 42.2 % (1043/2473) in the ET alone group vs. 46.2 % (684/1480) in the tirofiban with ET group (risk ratio (RR), 1.10 [95 % CI, 1.02-1.18]; P=0.02),mortality at 90 days (RR, 0.86 [95 % CI, 0.76-0.98]; P = 0.02). There is no significant between-group differences were found in excellent outcome (mRS score ≤1) (RR, 1.08 [95 % CI, 0.95-1.23]; P = 0.22), symptomatic intracranial hemorrhage (RR, 1.11 [95 % CI, 0.92-1.34]; P = 0.27). CONCLUSIONS These findings suggest that the use of ET combined with tirofiban in patients with acute stroke is safe and has the potential to reduce mortality and improve functional independence at 90 days.

Abstract
In a previously published clinical trial, we demonstrated that tirofiban was effective and safe in acute ischemic stroke (AIS) patients who did not undergo early recanalization treatments. We aimed to evaluate neuroimaging characteristics and their clinical significance to guide tirofiban treatment. In this post hoc analysis, location of infarcts (anterior circulation stroke [ACS] vs. posterior circulation stroke [PCS]), degree of cerebral artery stenosis (≤69% vs. ≥70% or occlusion), total infarct volume, and ASPECTS were used to predict the treatment effects of tirofiban, defined as the proportions of excellent and favorable functional outcome (modified Rankin Scale [mRS] score of 0-1, 0-2) at 90 days. ACS patients were more likely to achieve excellent (OR 2.08; 95% CI 1.25-3.45; p = 0.004) and favorable functional outcome (OR 2.28; 95% CI 1.24-4.22; p = 0.008) when treated with tirofiban. However, there was no significant difference in PCS patients between tirofiban and the control group. For patients with severe stenosis (≥70% or occlusion), tirofiban treatment improved the proportion of good outcomes (OR 2.84; 95% CI 1.44-5.60; p = 0.002 for mRS 0-1; OR 2.42; 95% CI 1.22-4.77; p = 0.011 for mRS 0-2). Meanwhile, we found that tirofiban improved outcome in patients with ASPECTS 8-10 and was independent of total infarct volume. These findings support the hypothesis that patients with ACS and severe stenosis may be recommended for tirofiban treatment, which can be predicted independent of total infarct volume.

Abstract
BACKGROUND China is one of the countries with the highest burden of stroke. Implementing multidimensional management guidelines will help clinicians practise evidence-based care, improve patient outcomes and alleviate societal burdens. This update of the 2019 edition will provide the latest comprehensive recommendations for the diagnosis and treatment of ischaemic cerebrovascular diseases. METHODS We conducted a comprehensive search on MEDLINE (via PubMed) up to 31 August 2023. The writing team established the recommendations through multiple rounds of online and offline discussions. Each recommendation was graded using the evidence grading algorithm developed by the Chinese Stroke Association (CSA). The draft was reviewed and finalised by the CSA Stroke Guidelines Writing Committee. RESULTS This update included revisions of 15 existing recommendations and 136 new recommendations in the following areas of stroke care: emergency assessment and diagnosis of ischaemic cerebrovascular disease, acute-phase reperfusion therapy, evaluation of underlying mechanisms, antithrombotic therapy, prevention and treatment of complications, and risk factor management. CONCLUSIONS This guideline updated the recommendations for the clinical management of ischaemic cerebrovascular disease from 2019.

Abstract
BACKGROUND Periprocedural antithrombotic treatment is a key determinant for the risk-benefit balance of emergent carotid artery stenting (eCAS) during stroke thrombectomy. We aimed to assess the safety and efficacy of three types of antithrombotic treatment. METHODS Retrospective review of prospectively collected endovascular databases in four comprehensive stroke centers, including consecutive cases of eCAS for tandem lesion strokes between January 2019 and July 2021. During this period, each center prospectively applied one of three periprocedural protocols: (a) two centers administered aspirin (250 mg IV); (b) one center administered aspirin and heparin (bolus+24 hours infusion); and (c) one center applied an aggressive antiplatelet strategy consisting of aspirin and clopidogrel (loading doses), with added intravenous tirofiban if in-stent thrombosis was observed during thrombectomy. Dichotomized comparisons of outcomes were performed between aggressive versus non-aggressive strategy (aspirin±heparin) and aspirin+heparin versus aspirin-alone groups. RESULTS Among 161 included patients, 62 received aspirin monotherapy, 38 aspirin+heparin, and 61 an aggressive treatment. Aggressive antiplatelet treatment was associated with an increased rate of excellent (modified Thrombolysis in Cerebral Infarction (mTICI) 2c-3) recanalization and reduced carotid stent thrombosis at day 1 (3.5% vs 16.3%), compared with non-aggressive strategy. There were no significant differences in hemorrhagic transformation or 90-day mortality. There was a tendency towards better clinical outcome with aggressive treatment, without reaching statistical significance. Addition of heparin to aspirin was not associated with an increased rate of carotid stent patency. CONCLUSIONS Aggressive antiplatelet treatment was associated with improved intracranial recanalization and carotid stent patency, without safety concerns. These findings have implications for randomized trials and may be of utility for clinicians when making antithrombotic treatment choices.

Efficacy and safety of low dose intravenous cangrelor in a consecutive cohort of patients undergoing neuroendovascular procedures. J Neurointerv Surg 2023; 16:88-93. [PMID: 36922032 DOI: 10.1136/jnis-2023-020094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 02/25/2023] [Indexed: 03/17/2023]
Abstract
BACKGROUND Cangrelor is an intravenous P2Y12 inhibitor with rapid onset and fast offset of antiplatelet action. Dose adjusted cangrelor based on platelet function testing is suggested to be advantageous for use during neuroendovascular procedures. In this study, we aimed to assess the efficacy and safety of this strategy. METHODS This retrospective study included consecutive patients who received low dose intravenous cangrelor (5 µg/kg; infusion 1 µg/kg/min) for ruptured (RIA) and unruptured (UIA) intracranial aneurysms, and acute ischemic stroke (AIS). Indications were acute stenting or intraluminal thrombus. Outcomes were assessed at 24 hours by brain CT and CT angiography. The primary efficacy outcome was the rate of stent occlusion or persistent intraluminal thrombus. The primary safety outcome was the rate of major hemorrhages. RESULTS 101 patients (56 men; median age (IQR) 59 (51-70) years) received low dose cangrelor for acute stenting (79/101 (78%)) and intraprocedural thrombus (22/101 (22%)). Overall, 5 (4.9%) patients experienced stent occlusion within 24 hours (RIA 3/28; AIS 2/52). There were no cases of failure among UIA patients. Stent mis-opening (fish mouthing or stenosis >50%) was significantly associated with stent occlusion (P<0.001). The overall rate of major hemorrhage was 2% (2/101), which occurred in AIS patients. Platelet reactivity unit (PRU) values were lower in those presenting with major hemorrhage (PRU 4 (SD 1.4) vs PRU 60 (SD 63); P=0.043). Mortality rate after cangrelor related hemorrhage was 1%. CONCLUSIONS Low dose cangrelor appears to be effective in preventing stent thrombosis and arterial patency with a low hemorrhagic risk.

Abstract
BACKGROUND Patients treated with acute carotid stenting (CAS) may have higher odds of a favorable outcome than those treated without CAS during thrombectomy in tandem occlusions. Antiplatelet therapy is associated with CAS to avoid stent thrombosis, which occurs in around 20% of patients and negatively impacts outcomes. In this study we compared two antiplatelet strategies in tandem occlusion strokes treated with CAS and intracranial thrombectomy in clinical practice. METHODS The Endovascular Treatment in Ischemic Stroke Registry is an ongoing prospective observational study involving 21 comprehensive stroke centers performing thrombectomy in France. We analyzed patients with atherosclerotic tandem occlusions treated with acute CAS and intracranial thrombectomy who received at least one antiplatelet agent. Aggressive antiplatelet therapy included oral or intravenous glycoprotein (GP) IIb/IIIa or P2Y12 inhibitors. The primary outcome was cervical carotid artery patency at day 1 imaging follow-up. RESULTS Among the 187 included patients, 124 (66.3%) received aspirin alone and 63 (33.7%) received aggressive antiplatelet therapy. There was no significant difference regarding safety outcomes, especially in symptomatic intracerebral hemorrhage, parenchymal hematoma, and procedural complications. There was a significantly higher rate of carotid stent patency at day 1 in the aggressive antiplatelet therapy group (81.7% vs 97.1%, aOR 17.49, 95% CI 1.10 to 277.2, p=0.042). Odds of favorable functional outcome (90-day modified Rankin Scale score 0-2) were similar between the groups (OR 3.04, 95% CI 0.64 to 14.25, p=0.158). CONCLUSIONS In tandem occlusions treated with CAS plus thrombectomy, an aggressive antiplatelet regimen was associated with an increased rate of carotid stent patency at day 1 without safety concerns. Randomized trials are warranted to confirm these findings.

Association of tirofiban treatment with outcomes following endovascular therapy in cardioembolic stroke: insights from the RESCUE BT randomized trial. Eur J Med Res 2023; 28:473. [PMID: 37915101 PMCID: PMC10621173 DOI: 10.1186/s40001-023-01406-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 09/28/2023] [Indexed: 11/03/2023] Open
Abstract
BACKGROUND AND PURPOSE The efficacy and safety of tirofiban in endovascular therapy for cardioembolic ischemic stroke patients remain controversial. This study aimed to evaluate the role of intravenous tirofiban before endovascular therapy in cardioembolic stroke. METHODS This post hoc analysis utilized data from the RESCUE BT (Endovascular Treatment With versus Without Tirofiban for Patients with Large Vessel Occlusion Stroke) trial, which was an investigator-initiated, randomized, double-blind, placebo-controlled trial. Participants were randomized to receive either tirofiban or a placebo in a 1:1 ratio before undergoing endovascular therapy. The study included patients aged 18 years or older, presenting with occlusion of the internal carotid artery or middle cerebral artery (MCA) M1/M2 within 24 h of the last known well time, and with a stroke etiology of cardioembolism. The primary efficacy outcome was global disability at 90 days, assessed using the modified Rankin Scale (mRS). The safety outcome included symptomatic intracranial hemorrhage (sICH) within 48 h and mortality within 90 days. RESULTS A total of 406 cardioembolic stroke patients were included in this study, with 212 assigned to the tirofiban group and 194 assigned to the placebo group. Tirofiban treatment did not correlate with a favorable shift towards a lower 90-day mRS score (adjusted common odds ratio [OR], 0.91; 95% CI 0.64-1.3; p = 0.617). However, the tirofiban group had a significantly higher risk of symptomatic intracranial hemorrhage (sICH) within 48 h (adjusted OR, 3.26; 95% CI 1.4-7.57; p = 0.006) compared to the placebo group. The adjusted odds ratio (aOR) for mortality within 90 days was 1.48 (95% CI 0.88-2.52; p = 0.143). CONCLUSIONS Tirofiban treatment was not associated with a lower level of disability and increased the incidence of sICH after endovascular therapy in cardioembolic stroke patients.

Abstract
BACKGROUND There is little data available to guide optimal anesthesia management during rescue intracranial angioplasty and stenting (ICAS) for failed mechanical thrombectomy (MT). We sought to compare the procedural safety and functional outcomes of patients undergoing rescue ICAS for failed MT under general anesthesia (GA) vs non-general anesthesia (non-GA). METHODS We searched the data from the Stenting and Angioplasty In Neuro Thrombectomy (SAINT) study. In our review we included patients if they had anterior circulation large vessel occlusion strokes due to intracranial internal carotid artery (ICA) or middle cerebral artery (MCA-M1/M2) segments, failed MT, and underwent rescue ICAS. The cohort was divided into two groups: GA and non-GA. We used propensity score matching to balance the two groups. The primary outcome was the shift in the degree of disability as measured by the modified Rankin Scale (mRS) at 90 days. Secondary outcomes included functional independence (90-day mRS0-2) and successful reperfusion defined as mTICI2B-3. Safety measures included symptomatic intracranial hemorrhage (sICH) and 90-day mortality. RESULTS Among 253 patients who underwent rescue ICAS, 156 qualified for the matching analysis at a 1:1 ratio. Baseline demographic and clinical characteristics were balanced between both groups. Non-GA patients had comparable outcomes to GA patients both in terms of the overall degree of disability (mRS ordinal shift; adjusted common odds ratio 1.29, 95% CI [0.69 to 2.43], P=0.43) and rates of functional independence (33.3% vs 28.6%, adjusted odds ratio 1.32, 95% CI [0.51 to 3.41], P=0.56) at 90 days. Likewise, there were no significant differences in rates of successful reperfusion, sICH, procedural complications or 90-day mortality among both groups. CONCLUSIONS Non-GA seems to be a safe and effective anesthesia strategy for patients undergoing rescue ICAS after failed MT. Larger prospective studies are warranted for more concrete evidence.

Abstract
OBJECTIVE This study aimed to investigate whether treatment with adjunct intravenous tirofiban is associated with improved outcomes following successful reperfusion in patients with intracranial atherosclerotic stroke. METHODS Patients with intracranial large artery atherosclerotic (LAA) stroke and an expanded Treatment in Cerebral Ischemia angiographic score of 2b50 to 3 from the Effect of Intravenous Tirofiban versus Placebo Before Endovascular Thrombectomy on Functional Outcomes in Large Vessel Occlusion Stroke (RESCUE BT) trial were included. The primary outcome was the difference in proportion of independent functional outcome (modified Rankin score of 0-2 at 90 days). Safety outcomes included the rates of symptomatic intracranial hemorrhage (sICH) and 90-day mortality. RESULTS Among the 382 patients with intracranial LAA stroke and successful reperfusion, 175 patients (45.8%) were treated with intravenous tirofiban and 207 (54.2%) with placebo. The proportion of patients with independent functional outcome at 90 days was 54.3% (95 out of 175) with tirofiban and 44.0% (91 out of 207) with placebo (adjusted odds ratio [aOR], 1.58; 95% CI, 1.02-2.44; p = 0.04). Intravenous tirofiban was not significantly associated with an increased risk of sICH (12/175 [6.9%] vs. 11/207 [5.3%]; aOR, 1.41; 95% CI, 0.59-3.34; p = 0.44) or 90-day mortality (21/175 [12.0%] vs. 34/207 [16.4%]; aOR, 0.71; 95% CI, 0.38-1.31; p = 0.27). INTERPRETATION Among patients with acute intracranial LAA stroke and successful reperfusion following endovascular thrombectomy, adjunct intravenous tirofiban was associated with a higher rate of independent functional outcome, without higher rates of sICH or mortality. Confirmatory randomized trials in these patients are desirable.

Systematic review and meta-analysis of the efficacy and safety of adjunctive use of tirofiban in patients treated with endovascular therapy for acute ischemic stroke at different embolic sites. Medicine (Baltimore) 2023; 102:e35091. [PMID: 37800797 PMCID: PMC10553052 DOI: 10.1097/md.0000000000035091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Accepted: 08/15/2023] [Indexed: 10/07/2023] Open
Abstract
BACKGROUND The use of tirofiban as an adjunct to endovascular therapy (EVT) for acute ischemic stroke has been controversial. We aimed to assess the differences in safety and efficacy of EVT adjuvant to tirofiban in patients with anterior circulation stroke (ACS) and posterior circulation stroke (PCS). METHODS We systematically searched Pubmed, Embase, Cochrane Library, and Web of Science. Cohort studies and randomized controlled trials that compared treatment with tirofiban combined with EVT and EVT alone were included in our meta-analysis. The safety outcomes were symptomatic intracranial hemorrhage, and 3-month mortality. The efficacy outcomes were good functional outcome, excellent functional outcome, and successful recanalization (mTICI ≥ 2b). We performed subgroup analyses of anterior and posterior circulation strokes. RESULTS We included 15 studies with 4608 patients. For safety outcomes, tirofiban significantly reduced 3-month mortality in the ACS subgroup (odd ratio [OR] = 0.80, 95% confidence interval [CI] = 0.65-0.98, P = .03) without increasing the rate of symptomatic intracranial hemorrhage (OR = 1.12, 95% CI = 0.88-1.44, P = .35). In the PCS subgroup, tirofiban significantly reduced 3-month mortality (OR = 0.63, 95% CI = 0.50-0.80, P = .0001) and symptomatic intracranial hemorrhage (OR = 0.60, 95% CI = 0.37-0.95, P = .03). For efficacy outcomes, in the ACS subgroup, tirofiban significantly improved good functional outcome (OR = 1.24, 95% CI = 1.06-1.45, P = .008) but did not improve recanalization (OR = 1.17, 95% CI = 0.93-1.47, P = .17) and excellent functional outcome (OR = 1.19, 95% CI = 0.97-1.46, P = .10). In the PCS subgroup, tirofiban significantly improved recanalization rate (OR = 1.94, 95% CI = 1.43-2.65, P < .0001) and did not improve good functional outcome (OR = 1.03, 95% CI = 0.81-1.30, P = .81) and excellent functional outcome (OR = 0.84, 95% CI = 0.58-1.20, P = .34). CONCLUSION In acute ischemic stroke patients undergoing EVT, tirofiban improves good functional outcomes in ACS patients and increases recanalization rates in PCS patients on the 1 hand, reduces mortality, and does not increase the risk of symptomatic intracranial hemorrhage on the other. Tirofiban is safe and effective in both anterior circulation stroke and posterior circulation stroke patients undergoing EVT. More large multicentre randomized controlled studies are needed in the future.

Impact of pre-treatment cerebral microbleeds on the outcomes of endovascular thrombectomy: A systematic review and meta-analysis. J Stroke Cerebrovasc Dis 2023; 32:107324. [PMID: 37660553 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 08/18/2023] [Accepted: 08/21/2023] [Indexed: 09/05/2023] Open
Abstract
OBJECTIVE/AIM To investigate the effect of cerebral microbleeds (CMBs) on the functional and safety outcomes of endovascular thrombectomy (EVT) in patients with acute ischemic stroke (AIS) due to large vessel occlusion (LVO). METHODS This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines for systematic review and meta-analysis. We included observational studies that recruited AIS-LVO patients, used susceptibility-sensitive magnetic resonance imaging (MRI) to detect CMBs, and examined the association between them and predefined outcome events. The extracted data included study and population characteristics, risk of bias domains, and outcome measures. The outcomes of interest included functional independence, revascularization success, procedural and hemorrhagic adverse events. We conducted a meta-analysis using the Mantel-Haenszel method and calculated the risk ratios. RESULTS Four studies with a total of 1,514 patients were included. A significant reduction in the likelihood of achieving a favorable functional outcome was observed in patients with CMBs (Risk ratio (RR) 0.69, 95% confidence interval (CI): 0.52 to 0.91, P=0.01). No significant differences were observed between the CMBs and no CMBs groups in terms of successful revascularization, mortality, intracranial hemorrhage (ICH), subarachnoid hemorrhage (SAH), and parenchymal hematoma. CONCLUSIONS The presence of CMBs significantly reduced the likelihood of achieving functional independence post-EVT in AIS-LVO patients. However, CMBs did not impact the rates of successful revascularization, mortality, or the occurrence of various hemorrhagic events. Future research should explore the mechanisms of this association and strategies to mitigate its impact.

Abstract
PURPOSE To investigate the safety and efficacy of baseline antiplatelet treatment in patients with acute ischemic stroke (AIS) undergoing mechanical thrombectomy (MT). MATERIALS AND METHODS Baseline use of antiplatelet medication before MT for (AIS) may provide benefit on reperfusion and clinical outcome but could also carry an increased risk of intracranial hemorrhage (ICH). All consecutive patients with AIS and treated with MT with and without intravenous thrombolysis (IVT) between January 2012 and December 2019 in all centers performing MT nationwide were reviewed. Data were prospectively collected in national registries (eg, SITS-TBY and RES-Q). Primary outcome was functional independence (modified Rankin Scale 0-2) at 3 months; secondary outcome was ICH. RESULTS Of the 4,351 patients who underwent MT, 1,750 (40%) and 666 (15%) were excluded owing to missing data from the functional independence and ICH outcome cohorts, respectively. In the functional independence cohort (n = 2,601), 771 (30%) patients received antiplatelets before MT. Favorable outcome did not differ in any antiplatelet, aspirin, and clopidogrel groups when compared with that in the no-antiplatelet group: odds ratio (OR), 1.00 (95% CI, 0.84-1.20); OR, 1.05 (95% CI, 0.86-1.27); and OR, 0.88 (95% CI, 0.55-1.41), respectively. In the ICH cohort (n = 3,685), 1095 (30%) patients received antiplatelets before MT. The rates of ICH did not increase in any treatment options (any antiplatelet, aspirin, clopidogrel, and dual antiplatelet groups) when compared with those in the no-antiplatelet group: OR, 1.03 (95% CI, 0.87-1.21); OR, 0.99 (95% CI, 0.83-1.18); OR, 1.10 (95% CI, 0.82-1.47); and OR, 1.43 (95% CI, 0.87-2.33), respectively. CONCLUSIONS Antiplatelet monotherapy before MT did not improve functional independence or increase the risk of ICH.

Abstract
BACKGROUND About 30 % of stroke patients have experienced unsuccessful reperfusion following endovascular therapy. Mechanical thrombectomy instruments may contribute to this by stimulating platelet aggregation. Tirofiban is a selective and rapidly activated antagonist of the platelets nonpeptide glycoprotein IIb/IIIa receptors that can reversibly suppress platelet aggregation. But, data from the medical literature are conflicting regarding its safety and efficacy for stroke patients. Hence, this study was designed to assess the safety and efficacy of tirofiban in stroke patients. METHODS Five major databases (PubMed, Scopus, Web of Science, Embase, and Cochrane library) were searched till December 2022. The Cochrane tool was used for risk of bias assessment, and the RevMan 5.4 was utilized for data analysis. RESULTS Seven RCTs with 2088 stroke patients were included. Tirofiban significantly increased the number of patients with mRS 0 score after 90 days than control; RR= 1.39, 95 %CI [1.15, 1.69]; p = 0.0006. Additionally, it reduced the NIHSS score after seven days; MD= -0.60, 95 %CI [-1.14, -0.06]; p = 0.03. However, tirofiban increased the incidence of intracranial haemorrhage (ICH); RR= 1.22, 95 %CI [1.03, 1.44]; p = 0.02. Other assessed outcomes showed insignificant results. CONCLUSIONS Tirofiban was associated with a higher mRS 0 score after three months and a lower NIHSS score after seven days. However, it is associated with higher ICH. Multicentric trials are required to provide more convincing proof of its utility.

Abstract
Stroke is the leading cause of severe long-term disability. Cell therapy has recently emerged as an approach to facilitate functional recovery in stroke. Although administration of peripheral blood mononuclear cells preconditioned by oxygen-glucose deprivation (OGD-PBMCs) has been shown to be a therapeutic strategy for ischemic stroke, the recovery mechanisms remain largely unknown. We hypothesised that cell-cell communications within PBMCs and between PBMCs and resident cells are necessary for a polarising protective phenotype. Here, we investigated the therapeutic mechanisms underlying the effects of OGD-PBMCs through the secretome. We compared levels of transcriptomes, cytokines, and exosomal microRNA in human PBMCs by RNA sequences, Luminex assay, flow cytometric analysis, and western blotting under normoxic and OGD conditions. We also performed microscopic analyses to assess the identification of remodelling factor-positive cells and evaluate angiogenesis, axonal outgrowth, and functional recovery by blinded examination by administration of OGD-PBMCs after ischemic stroke in Sprague-Dawley rats. We found that the therapeutic potential of OGD-PBMCs was mediated by a polarised protective state through decreased levels of exosomal miR-155-5p, and upregulation of vascular endothelial growth factor and a pluripotent stem cell marker stage-specific embryonic antigen-3 through the hypoxia-inducible factor-1α axis. After administration of OGD-PBMCs, microenvironment changes in resident microglia by the secretome promoted angiogenesis and axonal outgrowth, resulting in functional recovery after cerebral ischemia. Our findings revealed the mechanisms underlying the refinement of the neurovascular unit by secretome-mediated cell-cell communications through reduction of miR-155-5p from OGD-PBMCs, highlighting the therapeutic potential carrier of this approach against ischemic stroke.

Abstract
Purpose The oxygen and glucose deprivation-reoxygenation (OGDR) model is widely used to evaluate ischemic stroke and cerebral ischemia-reperfusion (I/R) injury in vitro. Excessively activated microglia produce pro-inflammatory mediators such as matrix metalloproteinases [MMPs] and their specific inhibitors, tissue inhibitors of metalloproteinases [TIMPs], causing neuronal damage. Ursolic acid (UA) acts as a neuroprotective agent in the rat middle cerebral artery occlusion/reperfusion (MCAO/R) model keeping the MMP/TIMP balance with underlying mechanisms unclear. Our study used OGDR model to determine whether and how UA reduces neuronal damage by reversing MMP/TIMP imbalance caused by microglia in I/R injury in vitro. Methods SH-SY5Y cells were first cultured with 95% N2 and 5% CO2 and then cultivated regularly for OGDR model. Cell viability was tested for a proper UA dose. We established a co-culture system with SH-SY5Y cells and microglia-conditioned medium (MCM) stimulated by lipopolysaccharide (LPS) and interferon-gamma (IFNγ). MMP9 and TIMP1 levels were measured with ELISA assay to confirm the UA effect. We added recombinant MMP9 (rMMP9) and TIMP1 neutralizing antibody (anti-TIMP1) for reconfirmation. Transmission electron microscopy was used to observe cell morphology, and flow cytometry and Annexin V-FITC and PI labeling for apoptotic conditions. We further measured the calcium fluorescence intensity in SH-SY5Y cells. Results The MCM significantly reduced cell viability of SH-SY5Y cells after OGDR (p<0.01), which was restored by UA (0.25 µM) (p<0.05), whereas lactate dehydrogenase activity, intraneuronal Ca2+ concentration, and apoptosis-related indexes were showed significant improvement after UA treatment (p<0.01). UA corrected the MMP/TIMP imbalance by decreasing MMP9 expression and increasing TIMP1 expression in the co-culture system (p<0.01) and the effects of UA on SH-SY5Y cells were mitigated by the administration of rMMP9 and anti-TIMP1 (p<0.01). Conclusion We demonstrated that UA inhibited microglia-induced neuronal cell death in an OGDR model of ischemic reperfusion injury by stabilizing the MMP9/TIMP1 imbalance.

Abstract
Endovascular treatment (EVT) has revolutionized the management of acute ischemic stroke (AIS), but almost half of patients undergoing EVT do not achieve a good outcome. Adjunctive therapies have been proposed to improve the outcomes of EVT in AIS. This review aims to summarize the current evidence on the use of adjunctive therapies in EVT for AIS, including antithrombotic agents, intra-arterial thrombolytics, cerebroprotective agents, normobaric oxygen, and hypothermia. Several adjunctive therapies have shown promise in improving the outcomes of EVT in AIS, but phase 3 clinical trials are needed to establish clinical efficacy. We summarize the advantages and disadvantages of adjunctive EVT treatments and outline the challenges that each of these therapies will face before being adopted in clinical practice.
