Association between stress hyperglycemia and outcomes in patients with acute ischemic stroke due to large vessel occlusion. CNS Neurosci Ther 2023. [PMID: 36914967 DOI: 10.1111/cns.14163] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 02/08/2023] [Accepted: 02/28/2023] [Indexed: 03/16/2023] Open
Abstract
AIMS This study aimed to evaluate the association between stress hyperglycemia ratio (SHR) and clinical outcomes at 90 days in acute ischemic stroke due to large vessel occlusion receiving endovascular treatment. METHODS The RESCUE BT trial was a multicenter, randomized, double-blind, placebo-controlled clinical trial, consisting of 948 stroke patients from 55 centers in China. A total of 542 patients with glucose and glycated hemoglobin (HbA1C) values at admission were included in this analysis. SHR, measured by glucose/HbA1C, was evaluated as both a tri-categorical variable (≤1.07 vs. 1.08-1.29 vs. ≥1.30) and a continuous variable. The primary outcome was a favorable functional outcome (modified Rankin Scale [mRS] score ≤2) at 90 days. The secondary outcome included excellent functional outcome (mRS score ≤1) and safety outcomes, such as 90-day mortality and intracranial hemorrhage. The study was registered with Chictr.org.cn (ChiCTR-INR-17014167). RESULTS Compared with patients in the lowest tertile of SHR, the highest tertile group had significantly lower odds of achieving favorable functional outcome of mRS score of 0-2 (adjusted odds ratio, 0.44; 95% confidence interval, 0.28-0.69; p < 0.001) and excellent clinical outcome of mRS score of 0-1 (adjusted odds ratio, 0.48; 95% confidence interval, 0.29-0.79; p = 0.004) at 90 days after adjusting for potential covariates. Similar results were observed after further adjustment for preexisting diabetes and Alberta Stroke Program Early Computed Tomography Score (ASPECTS). CONCLUSION Stress hyperglycemia ratio, as measured by the glucose/HbA1C, was associated with a decreased odds of achieving a favorable functional outcome in patients with acute large vessel occlusion stroke at 90 days.

Abstract
Alteplase is currently the only approved thrombolytic agent for treatment of acute ischaemic stroke, but interest is burgeoning in the development of new thrombolytic agents for systemic reperfusion with an improved safety profile, increased efficacy, and convenient delivery. Tenecteplase has emerged as a potential alternative thrombolytic agent that might be preferred over alteplase because of its ease of administration and reported efficacy in patients with large vessel occlusion. Ongoing research efforts are also looking at potential improvements in recanalisation with the use of adjunct therapies to intravenous thrombolysis. New treatment strategies are also emerging that aim to reduce the risk of vessel reocclusion after intravenous thrombolysis administration. Other research endeavors are looking at the use of intra-arterial thrombolysis after mechanical thrombectomy to induce tissue reperfusion. The growing implementation of mobile stroke units and advanced neuroimaging could boost the number of patients who can receive intravenous thrombolysis by shortening onset-to-treatment times and identifying patients with salvageable penumbra. Continued improvements in this area will be essential to facilitate the ongoing research endeavors and to improve delivery of new interventions.

Comparison of Safety and Efficacy after Emergency Stenting in Patients Exhibiting Intracranial Atherosclerotic Stenosis Associated with Large-vessel Occlusion with and without Intravenous Infusion of Tirofiban. Cardiovasc Intervent Radiol 2023; 46:377-384. [PMID: 36797426 PMCID: PMC10014670 DOI: 10.1007/s00270-023-03372-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 01/23/2023] [Indexed: 02/18/2023]
Abstract
PURPOSE Intracranial rescue stent angioplasty is a bailout strategy for acute stroke patients in cases of unsuccessful endovascular thrombectomy due to underlying atherosclerotic stenosis. However, there is no consensus on a preprocedural and intraprocedural antiplatelet regimen. The aim of this single-centre study was to compare the safety and efficacy of emergency stenting in patients exhibiting intracranial atherosclerotic stenosis-related acute large-vessel occlusion with or without peri-interventional intravenous infusion of tirofiban. MATERIALS AND METHODS We performed a retrospective analysis of 78 patients who were treated with rescuestent angioplasty between 2010 and 2019 due to acute ischaemic stroke. The patients were divided into 2 groups: those who received peri-interventional intravenous tirofiban and those who did not receive tirofiban. We compared clinical safety and functional outcomes in both treatment groups with symptomatic haemorrhage as the primary endpoint. Bivariate and multivariable logistic regression was performed to investigate the association between tirofiban and outcome measures. RESULTS Thirty-seven patients were treated with intravenous tirofiban (47.4%), and 41 patients did not receive intravenous tirofiban (52.6%). Statistical analysis revealed no significant difference between the two groups in the rate of symptomatic haemorrhage (16.2% in the tirofiban group versus 14.6% in the control group, p = 0.847). The 3-month mortality (21.6% in the tirofiban group versus 17.1% in the control group, p = 0.611) and good functional outcomes according to the modified Rankin scale (45.9% versus 34.1%, p = 0.289) were comparable. CONCLUSION The results of our study suggest that the application of tirofiban for rescue stenting after failed mechanical thrombectomy is safe.

Abstract
Endovascular treatment is a highly effective therapy for acute ischemic stroke due to large vessel occlusion. However, in clinical practice, nearly half of the patients do not have favorable outcomes despite successful recanalization of the occluded artery. This unfavorable outcome can be defined as having clinically ineffective reperfusion. The objective of the review is to describe clinically ineffective reperfusion after endovascular therapy and its underlying risk factors and mechanisms, including initial tissue damage, cerebral edema, the no-reflow phenomenon, reperfusion injury, procedural features, and variations in postprocedural management. Further research is needed to more accurately identify patients at a high risk of clinically ineffective reperfusion after endovascular therapy and to improve individualized periprocedural management strategies, to increase the chance of achieving favorable clinical outcomes.

Abstract
INTRODUCTION Mechanical thrombectomy is now widely used in acute ischaemic stroke, but its adjunctive antiplatelet aggregation regimen is controversial. This study aimed to investigate the safety and efficacy of tirofiban in patients with acute ischaemic stroke (AIS) who underwent mechanical thrombectomy. METHODS We systematically searched Pubmed, Embase, Cochrane Library, and Web of science. Randomized controlled studies and cohort studies comparing the tirofiban group and non-tirofiban group (control group) in patients with AIS who underwent mechanical thrombectomy. The primary safety outcomes were symptomatic intracranial hemorrhage (sICH), 3-month mortality, and re-occlusion rate. The primary efficacy outcomes were good functional outcome (mRS 0-2), excellent functional outcome (mRS 0-1), and successful recanalization (mTICI≥2b). RESULTS We included 22 studies with a total of 6062 patients. For safety outcomes, the tirofiban group had a non-significantly higher rate of sICH (OR = 0.90, 95 % CI = 0.73-1.10, P = 0.29) and a significantly lower rate of re-occlusion (OR = 0.40, 95 % CI = 0.19-0.82, P = 0.01) and 3-month mortality (OR = 0.71, 95 % CI = 0.61-0.82, P < 0.00001) compared to the control group. In terms of efficacy outcomes, significant improvement in good functional outcomes (mRS 0-2) (OR = 1.24, 95 % CI = 1.11-1.39, P = 0.0002) and recanalization rate (OR = 1.38, 95% CI = 1.17-1.62, P = 0.0001) compared to tirofiban, but not significant improvement in excellent functional outcomes(OR = 1.14, 95 % CI = 0.93-1.39, P = 0.21). In addition, compared with cardiogenic stroke, the large atherosclerotic stroke had a higher rate of good functional outcome (OR = 1.58, 95 % CI = 1.18-2.11, P = 0.002) and a lower rate of 3-month mortality (OR = 0.58, 95 % CI = 0.39-0.85, P = 0.005). Subgroup analysis by route of administration showed a significant improvement in good functional outcome in the intravenous group (OR = 1.27, 95 % CI = 1.08-1.50, P = 0.004), while no significant difference was found between the arterial and arteriovenous groups. CONCLUSION Treatment with tirofiban in patients with AIS with mechanical thrombectomy is effective in improving functional prognosis, arterial recanalization rates, and reducing 3-month mortality and re-occlusion rates, particularly in patients with large atherosclerotic stroke, without increasing the rate of symptomatic intracranial hemorrhage. Intravenous administration of tirofiban significantly improves the clinical prognosis compared to arterial administration. Tirofiban is effective and safe in patients with AIS.

Abstract
BACKGROUND In 2015, mechanical thrombectomy (MT) was deemed the standard of care for acute ischemic stroke (AIS) in the anterior circulation due to large vessel occlusion (LVO). To determine if outcomes in patients treated with MT have changed, we conducted a systematic review and meta-analysis of published randomized controlled trials (RCTs). METHODS A systematic literature review of the English language literature was conducted using PubMed. We included RCTs that focused on patients with AIS treated with MT. The primary outcome of interest was good functional outcome defined as modified Rankin Scale (mRS) 0-2 at 90 days. Safety outcomes included rates of symptomatic intracranial hemorrhage (sICH) and mortality at 90 days. Using Joinpoint Regression Analysis Program, we calculated the average annual percent change (AAPC) for the outcomes of interest. RESULTS We included 23 RCTs with 5784 patients. The years of mid-enrollment among the included RCTs ranged from 2012-2020. There was an AAPC of +3.82% between 2012 and 2020 (95% CI 0.4 to 7.3; P-value = 0.033) in rates of good functional outcome. There was an AAPC of +6.98% between 2012 and 2020 (95% CI 0.5 to 13.9; P-value = 0.039) in rates of sICH. There was an AAPC of -0.49% between 2012 and 2020 (95% CI -4.4 to 3.5; P-value = 0.77) in rates of mortality. CONCLUSION Between 2012 and 2020, rates of good functional outcome and sICH increased, while rates of mortality remained consistent in RCTs investigating MT for AIS. Multiple factors likely influenced our results, including increased use of MT and utilization of adjunctive therapies alongside MT.

Abstract
PURPOSE To provide recommendations for the anaesthetic and peri-operative management for thrombectomy procedure in stroke patients DESIGN: A consensus committee of 15 experts issued from the French Society of Anaesthesia and Intensive Care Medicine (Société Française d'Anesthésie et Réanimation, SFAR), the Association of French-language Neuro-Anaesthetists (Association des Neuro-Anesthésistes Réanimateurs de Langue Francaise, ANARLF), the French Neuro-Vascular Society (Société Francaise de Neuro-Vasculaire, SFNV), the French Neuro-Radiology Society (Société Francaise de Neuro-Radiologie, SFNR) and the French Study Group on Haemostasis and Thrombosis (Groupe Français d'Études sur l'Hémostase et la Thrombose, GFHT) was convened, under the supervision of two expert coordinators from the SFAR and the ANARLF. A formal conflict-of-interest policy was developed at the outset of the process and enforced throughout. The entire guideline elaboration process was conducted independently of any industry funding. The authors were required to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide their assessment of quality of evidence. METHODS Four fields were defined prior to the literature search: (1) Peri-procedural management, (2) Prevention and management of secondary brain injuries, (3) Management of antiplatelet and anticoagulant treatments, (4) Post-procedural management and orientation of the patient. Questions were formulated using the PICO format (Population, Intervention, Comparison, and Outcomes) and updated as needed. Analysis of the literature was then conducted and the recommendations were formulated according to the GRADE methodology. RESULTS The SFAR/ANARLF/SFNV/SFNR/GFHT guideline panel drew up 18 recommendations regarding anaesthetic management of mechanical thrombectomy procedures. Due to a lack of data in the literature allowing to conclude with high certainty on relevant clinical outcomes, the experts decided to formulate these guidelines as "Professional Practice Recommendations" (PPR) rather than "Formalized Expert Recommendations". After two rounds of rating and several amendments, a strong agreement was reached on 100% of the recommendations. No recommendation could be formulated for two questions. CONCLUSIONS Strong agreement among experts was reached to provide a sizable number of recommendations aimed at optimising anaesthetic management for thrombectomy in patients suffering from stroke.

Abstract
BACKGROUND AND PURPOSE Intracranial atherosclerotic disease (ICAD) is a common etiology of acute vertebrobasilar artery occlusion (VBAO) in Asia, which complicated endovascular treatment (EVT). We aimed to investigate the incidence, impacts, and predictors of ICAD in VBAO. METHODS Subjects were selected from the Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke registry and divided into two groups based on whether underlying ICAD existed. Underlying ICAD was determined when the following situations arise in the occlusion site during EVT: (1) fixed stenosis degree >70% or (2) stenosis >50% with distal blood flow impairment or evidence of repeated reocclusion. Multivariable regression models were used to investigate the effect of underlying ICAD on outcomes measured by modified Rankin Scale (mRS) score at 90 days and to identify baseline characteristics associated with underlying ICAD. RESULTS Among the 315 patients enrolled, 171 (54.3%) had underlying ICAD. Favorable functional outcomes (mRS 0-3) occurred in 79 of 163 patients (48.5%) with ICAD and 69 of 137 patients (50.4%) without ICAD (p = 0.743). Outcomes were similar between the two groups and remained similar after adjusting for the confounders. History of hypertension and elevated admission neutrophil to lymphocyte ratio were strong predictors of underlying ICAD, whereas history of atrial fibrillation and distal basilar artery occlusion were negative predictors. CONCLUSIONS In our study, underlying ICAD was recognized in approximately half of the VBAO patients, leading to comparable outcomes after more complex EVT strategies. Some baseline characteristics were identified to be predictors for underlying ICAD, which were helpful to guide the EVT strategies before the procedure.

Abstract
Few studies have reported the clinical outcomes of older adult patients with acute anterior circulation large-vessel occlusion (LVO) who underwent mechanical thrombectomy (MT). Therefore, we investigated the safety, functional outcomes, and predictors of MT for anterior circulation LVO in older adults. We enrolled patients with acute anterior circulation LVO from May 2018 to October 2021 in this retrospective study. Patients were divided into older (≥80 years) and young (<80 years) groups. Multivariable logistic regression analyses determined the safety, functional outcomes, and predictors of MT for anterior circulation LVO. We divided 1182 patients with acute ischemic stroke into young (18-79 years; 1028 patients) and older (≥80 years; 154 patients) groups. Compared with the young group, the older group had more unfavorable functional outcomes and increased mortality (P = .003). In the older adult patients, lower initial NIHSS score and higher ASPECTS were correlated with good outcomes. On the contrary, higher initial NIHSS score and lower ASPECTS were related to increased mortality. No difference was detected in symptomatic intracranial hemorrhage within 48 h between two groups. Increasing age was associated with lower rates of favorable functional outcomes and higher mortality rates. The lower initial NIHSS score combined with the higher ASPECTS may predict functional outcomes post-thrombectomy in older adults.

[PMID: 36481613 PMCID: PMC10568592 DOI: 10.1159/000527483] [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: 08/24/2022] [Accepted: 10/05/2022] [Indexed: 09/05/2023] Open
Abstract
INTRODUCTION The aim of this study was to test the hypothesis that intravenous tirofiban improves functional outcomes without promoting the risk of intracranial hemorrhage (ICH) in stroke secondary to basilar artery occlusion (BAO) receiving endovascular thrombectomy. METHODS Patients with acute BAO stroke who were treated with endovascular thrombectomy and had tirofiban treatment information were derived from "BASILAR": a nationwide, prospective registry. All eligible patients were divided into tirofiban and no-tirofiban groups according to whether tirofiban was used intravenously. The primary endpoint was the 90-day severity of disability as assessed by the modified Rankin scale score. Safety outcomes were the frequency of ICH and mortality. RESULTS Of 645 patients included in this cohort, 363 were in the tirofiban group and 282 were in the no-tirofiban group. Thrombectomy with intravenous tirofiban reduced the 90-day disability level over the range of the modified Rankin scale (adjusted common odds ratio, 2.08; 95% confidence interval (CI), 1.45-2.97; p < 0.001). The 90-day mortality of patients in the tirofiban group was lower than that in the no-tirofiban group (41.6% vs. 52.1%; adjusted hazard ratio, 0.60; 95% CI, 0.47-0.77; p < 0.001). The frequency of any ICH (6.7% vs. 13.7%; p = 0.004) and symptomatic ICH (4.8% vs. 10.1%; p = 0.01) in the tirofiban group was significantly lower than that in the no-tirofiban group. CONCLUSIONS In patients with acute BAO stroke who underwent endovascular treatment, intravenous tirofiban might be associated with favorable outcome, reduced mortality, and a decreased frequency of ICH.

[PMID: 36341753 DOI: 10.1016/s0140-6736(22)01882-7] [Citation(s) in RCA: 76] [Impact Index Per Article: 38.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 09/14/2022] [Accepted: 09/21/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND The optimum systolic blood pressure after endovascular thrombectomy for acute ischaemic stroke is uncertain. We aimed to compare the safety and efficacy of blood pressure lowering treatment according to more intensive versus less intensive treatment targets in patients with elevated blood pressure after reperfusion with endovascular treatment. METHODS We conducted an open-label, blinded-endpoint, randomised controlled trial at 44 tertiary-level hospitals in China. Eligible patients (aged ≥18 years) had persistently elevated systolic blood pressure (≥140 mm Hg for >10 min) following successful reperfusion with endovascular thrombectomy for acute ischaemic stroke from any intracranial large-vessel occlusion. Patients were randomly assigned (1:1, by a central, web-based program with a minimisation algorithm) to more intensive treatment (systolic blood pressure target <120 mm Hg) or less intensive treatment (target 140-180 mm Hg) to be achieved within 1 h and sustained for 72 h. The primary efficacy outcome was functional recovery, assessed according to the distribution in scores on the modified Rankin scale (range 0 [no symptoms] to 6 [death]) at 90 days. Analyses were done according to the modified intention-to-treat principle. Efficacy analyses were performed with proportional odds logistic regression with adjustment for treatment allocation as a fixed effect, site as a random effect, and baseline prognostic factors, and included all randomly assigned patients who provided consent and had available data for the primary outcome. The safety analysis included all randomly assigned patients. The treatment effects were expressed as odds ratios (ORs). This trial is registered at ClinicalTrials.gov, NCT04140110, and the Chinese Clinical Trial Registry, 1900027785; recruitment has stopped at all participating centres. FINDINGS Between July 20, 2020, and March 7, 2022, 821 patients were randomly assigned. The trial was stopped after review of the outcome data on June 22, 2022, due to persistent efficacy and safety concerns. 407 participants were assigned to the more intensive treatment group and 409 to the less intensive treatment group, of whom 404 patients in the more intensive treatment group and 406 patients in the less intensive treatment group had primary outcome data available. The likelihood of poor functional outcome was greater in the more intensive treatment group than the less intensive treatment group (common OR 1·37 [95% CI 1·07-1·76]). Compared with the less intensive treatment group, the more intensive treatment group had more early neurological deterioration (common OR 1·53 [95% 1·18-1·97]) and major disability at 90 days (OR 2·07 [95% CI 1·47-2·93]) but there were no significant differences in symptomatic intracerebral haemorrhage. There were no significant differences in serious adverse events or mortality between groups. INTERPRETATION Intensive control of systolic blood pressure to lower than 120 mm Hg should be avoided to prevent compromising the functional recovery of patients who have received endovascular thrombectomy for acute ischaemic stroke due to intracranial large-vessel occlusion.

Abstract
PURPOSE To identify and compare the predictors of failure of early neurological improvement (fENI)after successful EVT for anterior circulation large vessel occlusion (ACLVO) and posterior circulation LVO (PCLVO). METHODS Subjects were selected from the ANGEL-ACT registry. fENI was defined as unchanged or worsened in National Institutes of Health Stroke Scale score (NIHSS) between admission and 24 h after EVT. Predictors of fENI after successful EVT (mTICI 2b-3) were determined via center-adjusted analyses. Univariable and multivariable comparisons between ACLVO and PCLVO were performed. RESULTS A total of 1447 patients, 1128 were with ACLVO, and 319 were with PCLVO. Among the patients with ACLVO, there were 409 patients (36.3%) with fENI and 719 patients (63.7%) with ENI. We observed that pre-stroke mRS scale score of 2 (odd ratio[OR] 95% confidence interval[CI], 6.93[1.99-24.10], P = 0.002), initial NIHSS score (OR per point[95%CI], 0.97[0.95-0.99], P = 0.012), diabetes (OR[95%CI], 1.56[1.08-2.25], P = 0.017), previous ICH (OR[95%CI] 9.21[1.76-48.15], P = 0.008), local anesthesia (OR[95%CI] 1.63[1.10-2.42], P = 0.014), onset-to-puncture time (OR[95%CI], 1.001[1.000-1.001], P = 0.009), symptomatic ICH (OR[95%CI] 3.90[2.27-6.69], P < 0.001), and continued use of tirofiban within 2 h after EVT (OR[95%CI], 0.69[0.51-0.93], P = 0.014) were independent predictors of fENI of ACLVO after EVT. Among the patients with PCLVO, there were 112 patients (35.1%) with fENI and 207 patients (64.9%) with ENI. In contrast, admission SBP (OR[95%CI], 0.98[0.97-0.99], P = 0.012), and vascular dissection within 2 h after EVT (OR[95%CI], 7.23[1.33-39.13], P = 0.022) were independent predictors of fENI of PCLVO after EVT. CONCLUSION In selected patients, successful EVT can lead to similar outcomes in PCLVO and ACLVO. Some predictors of fENI in both anterior circulation and posterior circulation were identified in our study, which should be highly considered in the clinical practice in LVO patients undergoing EVT.
