Frailty scores impact the outcomes of urgent carotid interventions in acute stroke patients: A comprehensive analysis of risk and prognosis. J Vasc Surg 2024:S0741-5214(24)01667-7. [PMID: 39111588 DOI: 10.1016/j.jvs.2024.07.096] [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: 03/03/2024] [Revised: 07/19/2024] [Accepted: 07/28/2024] [Indexed: 09/08/2024]
Abstract
BACKGROUND Carotid artery disease is an important cause of ischemic strokes. Patient selection for urgent carotid interventions (ie, urgent carotid endarterectomy [uCEA] and urgent carotid artery stenting [uCAS]) performed within 2 weeks of an event during the index hospitalization is based primarily on a patient's overall health and risk profile. Identifying high-risk patients remains a challenge. Frailty, a decrease in function related to aging, has emerged as an important factor in the treatment of the elderly population. This study aimed to design a quantitative risk score based on frailty for patients undergoing uCEA and uCAS after an acute stroke. METHODS A total of 307 acute stroke patients treated with uCEA or uCAS were identified from a prospectively maintained database. Frailty scores were calculated using the Hospital Frailty Risk Index based on International Classificiation of Diseases, 10th edition, codes. Stroke-specific risk categories were created based on the incidence of stroke, death, and myocardial infarction (MI) associated with frailty scores. Primary end points included 30-day stroke, death, and MI, and the secondary end point was discharge modified Rankin scale (mRS). Statistical analyses were performed using SAS software. RESULTS The average age was 65.9 years; hypertension, a history of tobacco use, and hyperlipidemia were the most common comorbidities. The median Hospital Frailty Risk Score was 27; the majority of patients in this study were in the intermediate and high risk frailty groups (50.5% and 41.7%, respectively). uCAS patients had a higher median presenting National Institutes of Health Stroke Scale (NIHSS) (8 vs 2; P < .001) and shorter median time to intervention compared with uCEA patients (1 day vs 3 days; P ≤ .001). The 30-day composite stroke, death, and MI rate was 8.1%, with higher rates observed in patients with frailty scores of >30 (11.7%) and uCAS (12.2%). Hemorrhagic conversion and death were more common in uCAS patients. Functional independence (mRS 0-2) was observed in uCEA patients after minor stroke and in uCAS patients after minor or moderate stroke. Patients with high-risk frailty score (>30) presenting with a moderate stroke were more likely to be functionally dependent (mRS > 2) on discharge (67 vs 41.3%; P < .001). CONCLUSIONS Frailty is a valuable prognosticative tool for clinical outcomes in patients undergoing urgent carotid interventions after an acute stroke. Higher frailty scores were associated with increased stroke, death, and MI rates. Frailty also influenced functional dependence at discharge, particularly in patients with moderate stroke. These findings highlight the importance of considering frailty in the decision-making process for carotid interventions. Further research is needed to validate these findings and explore interventions to mitigate the impact of frailty on outcomes.

Hayson A, Burton J, Allen J, Sternbergh WC, Fort D, Bazan HA. Impact of presenting stroke severity and thrombolysis on outcomes following urgent carotid interventions. J Vasc Surg 2023; 78:702-710.

Abstract
BACKGROUND Carotid interventions are increasingly performed in select patients following acute stroke. We aimed to determine the effects of presenting stroke severity (National Institutes of Health Stroke Scale [NIHSS]) and use of systemic thrombolysis (tissue plasminogen activator [tPA]) on discharge neurological outcomes (modified Rankin scale [mRS]) after urgent carotid endarterectomy (uCEA) and urgent carotid artery stenting (uCAS). METHODS Patients undergoing uCEA/uCAS at a tertiary Comprehensive Stroke Center (January 2015 to May 2022) were divided into two cohorts: (1) no thrombolysis (uCEA/uCAS only) and (2) use of thrombolysis before the carotid intervention (tPA + uCEA/uCAS). Outcomes were discharge mRS and 30-day complications. Regression models were used to determine an association between tPA use and presenting stroke severity (NIHSS) and discharge neurological outcomes (mRS). RESULTS Two hundred thirty-eight patients underwent uCEA/uCAS (uCEA/uCAS only, n = 186; tPA + uCEA/uCAS, n = 52) over 7 years. In the thrombolysis cohort compared with the uCEA/uCAS only cohort, the mean presenting stroke severity was higher (NIHSS = 7.6 vs 3.8; P = .001), and more patients presented with moderate to severe strokes (57.7% vs 30.2% with NIHSS >4). The 30-day stroke, death, and myocardial infarction rates in the uCEA/uCAS only vs tPA + uCEA/uCAS were 8.1% vs 11.5% (P = .416), 0% vs 9.6% (P < .001), and 0.5% vs 1.9% (P = .39), respectively. The 30-day stroke/hemorrhagic conversion and myocardial infarction rates did not differ with tPA use; however, the difference in deaths was significantly higher in the tPA + uCEA/uCAS cohort (P < .001). There was no difference in neurological functional outcome with or without thrombolysis use (mean mRS, 2.1 vs 1.7; P = .061). For both minor strokes (NIHSS ≤4 vs NIHSS >4: relative risk, 1.58 vs 1.58, tPA vs no tPA, respectively, P = .997) and moderate strokes (NIHSS ≤10 vs NIHSS >10: relative risk, 1.94 vs 2.08, tPA vs no tPA, respectively; P = .891), the likelihood of discharge functional independence (mRS score of ≤2) was not influenced by tPA. CONCLUSIONS Patients with a higher presenting stroke severity (NIHSS) had worse neurological functional outcomes (mRS). Patients presenting with minor and moderate strokes were more likely to have discharge neurological functional independence (mRS of ≤2), regardless of whether they received tPA or not. Overall, presenting NIHSS is predictive of discharge neurological functional autonomy and is not influenced by the use of thrombolysis.

J Thorac Cardiovasc Surg 2023; 165:1346-1355.e5. [PMID: 34053738 DOI: 10.1016/j.jtcvs.2021.04.082] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 04/16/2021] [Accepted: 04/19/2021] [Indexed: 12/29/2022]
Abstract
OBJECTIVES As the application of transcatheter aortic valve replacement (TAVR) expands, the longitudinal implications of periprocedural complications are increasingly relevant. We examine the influence of TAVR complications on midterm survival. METHODS Patients undergoing transfemoral TAVR at our institution between November 2011 and June 2018 were reviewed. Stroke severity was classified according to the National Institutes of Health stroke score. Kaplan-Meier analysis was used to assess survival, and a Cox proportional hazards model was created to examine independent associations with survival. The median follow-up time was 36 months for a total of 2789 patient-years. RESULTS Overall, 866 patients were included. The mean age was 80 ± 9.5 years and mean Society of Thoracic Surgeons score was 4.8% ± 2.7%. The mortality rate at 30-days was 2.8% and 11.8% at 1 year. In-hospital left bundle branch block and 30-day permanent pacemaker insertion occurred in 14.8% and 7.9%, respectively. Postprocedural greater-than-mild paravalvular leak was present in 4.4% and stroke occurred in 3.8% at 30-days. Greater-than-mild paravalvular leak was associated with decreased survival at 2 years (P = .02), but not at 5 years. Severe stroke was independently associated with decreased survival at 5 years (hazard ratio, 5.73; 95% confidence interval, 2.29-14.36; P ≤ .001); however, the effect of nonsevere stroke did not reach significance (hazard ratio, 1.69; 95% confidence interval, 0.82-3.47; P = .152). CONCLUSIONS Severe stroke was independently associated with decreased 5-year survival and initial risks associated with paravalvular leak may be attenuated over the midterm following transfemoral TAVR. Strategies to minimize the incidence of stroke and paravalvular leak must be prioritized to improve longitudinal outcomes after TAVR.

Factors associated with delay to carotid endarterectomy for acute ischaemic stroke in South Australia: A multicentre retrospective cohort study. J Stroke Cerebrovasc Dis 2023; 32:106916. [PMID: 36565521 DOI: 10.1016/j.jstrokecerebrovasdis.2022.106916] [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: 09/19/2022] [Accepted: 11/27/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND The greatest benefits of carotid endarterectomy (CEA) accrue when performed within two weeks of acute ischaemic stroke (AIS) due to symptomatic carotid stenosis. Previous studies have identified multiple factors contributing to CEA delay. AIMS To determine factors associated with delayed CEA in patients admitted to tertiary stroke centres within a major metropolitan region with AIS METHODS: In a retrospective cohort study, consecutive patients admitted to the tertiary hospitals with stroke units within South Australia (Lyell McEwin Hospital, Royal Adelaide Hospital and Flinders Medical Centre) between 2016 to 2020 were included. Univariable and multivariable logistic regression were used to identify individual factors associated with time from symptom onset to CEA of over two weeks. RESULTS A total of 174 patients were included. The median time to CEA was 5 days (IQR 3-9.75). Delayed CEA beyond 14 days occurred in 28/174 (16%). Factors most associated with delayed CEA included presentation to a tertiary hospital without onsite Vascular Surgical Unit (OR 3.71, 95%CI 1.31-10.58), history of previous stroke (OR 3.38, 95% CI 1.11-9.84) and presenting NIHSS above 6 (OR 5.16, 95% CI 1.60-16.39). CONCLUSION This study identified that presentation to a tertiary hospital without a Vascular Surgery Unit, history of previous stroke and presenting NIHSS above 6 were associated with delay to CEA in AIS patients in South Australia. Interventional studies aiming to improve the proportion of patients that receive CEA within 14 days are required.

Elective or Urgent Carotid Endarterectomy in Symptomatic Patients: Analysis Based on the Type and Timing of Neurological Symptoms. Ann Vasc Surg 2023; 90:7-16. [PMID: 36503019 DOI: 10.1016/j.avsg.2022.10.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 09/23/2022] [Accepted: 10/23/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND The aim of this study was to retrospectively analyse perioperative and long-term outcomes of carotid endarterectomy (CEA) performed in symptomatic patients in a high-volume academic vascular centre, stratifying them according to the type of preoperative symptoms and the timing of surgery with respect to the indexed neurological event. METHODS From January 2014 to December 2020, 1,369 consecutive CEAs were performed at our institution. Data concerning these interventions were prospectively collected in a dedicated database including data concerning preoperative assessment, surgical details, perioperative (<30 days) outcomes, and long-term outcomes. A retrospective analysis of the database was performed, and 213 interventions performed in symptomatic patients were found. We identified 2 subgroups of patients: patients with stable neurological symptoms (not recent transient ischemic attack (TIA) or stable major disabling stroke, stable group, and 157 patients) and patients with unstable neurological symptoms (recent TIA, crescendo TIAs, stroke in evolution, acute/recent minor stroke, unstable group, and 56 patients). Perioperative outcomes were analysed in terms of mortality, major neurological events, and local or systemic complications The results were compared using the χ2 test; these were also analysed on the basis of the presenting symptom (isolated TIA, crescendo TIA, stroke in evolution, acute/recent minor stroke, stabilized stroke) and the timing of the intervention relative to the onset of the symptom. Long term results were analysed using the life-table analysis and Kaplan-Meier curves in terms of survival, stroke-free survival, absence of neurological symptoms, and absence of significant restenosis. RESULTS Overall, 30-day stroke and death rate were 4.2%. (3.1% vs. 7%, P = 0.2). Two deaths occurred at 30 days, both in the stable group (mortality 1.2%, P = 0.4 compared to the unstable group), but no fatal strokes were recorded in the overall sample. No differences were found in terms of new perioperative neurological events and local complications between the 2 groups. We found a trend toward poorer perioperative results in patients operated on within 48 hr from the indexed event and in patients operated on for stroke in evolution or acute/recent stroke, whereas we found a trend toward better results in favour of patients operated on between 8 and 14 days (P = 0.08). The median duration of follow-up was 24.8 months (range 1-78); at 5 years we did not find significant differences in terms of survival and stroke-free survival rates between 2 groups. CONCLUSIONS In our experience, carotid surgery in symptomatic patients provided satisfactory results, particularly in patients with stable neurological status. Among unstable patients, the rate of complications significantly increases, mainly among treated in the very early (<48 hr) period for stroke in evolution or acute/recent stroke. Once the perioperative risk is overcome, the results in the long-term setting are similarly good, both in stable and in unstable patients.

Risk of Liver Fibrosis Is Associated with More Severe Strokes, Increased Complications with Thrombolysis, and Mortality. J Clin Med 2023; 12:jcm12010356. [PMID: 36615156 PMCID: PMC9821417 DOI: 10.3390/jcm12010356] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 12/22/2022] [Accepted: 12/29/2022] [Indexed: 01/04/2023] Open
Abstract
The Fibrosis (FIB)-4 index is an established non-invasive test to detect liver fibrosis. Liver fibrosis is postulated to be one of the predictors of the risk of symptomatic Intracranial Haemorrhage (SICH) after intravenous tissue plasminogen activator (IV tPA) therapy, the mainstay of treatment following acute ischemic stroke (AIS). However, SICH is a feared complication of thrombolytic therapy. We aimed to evaluate the association of FIB-4 with outcomes of AIS after IV tPA. Consecutive AIS patients receiving IV tPA from 2006 to 2018 at a single stroke centre were studied in a retrospective cohort study. Multivariable adjusted logistic regression was performed to assess associations of FIB-4 with outcomes. The primary outcome was SICH, and secondary outcomes included functional independence (mRS of 0−2) and mortality measured at 90 days. Among 887 patients (median age: 67 (IQR: 57−77)), 342 had FIB-4 < 1.3 and 161 had FIB-4 > 2.67. A greater proportion of moderate to severe strokes (NIHSS ≥10) occurred in the FIB-4 > 2.67 group (n = 142, 88.8%) compared to the FIB-4 < 1.3 group (n = 208, 61.2%). Amongst the different stroke subtypes, median FIB-4 was highest in cardioembolic stroke (CES) compared to the 3 other non-CES stroke subtypes (1.90 (IQR: 1.41−2.69)). Following IV tPA, having FIB-4 > 2.67 was associated with an increased rate of SICH (adjusted OR: 4.09, 95% CI: 1.04−16.16, p = 0.045) and increased mortality (adjusted OR 3.05, 95% CI: 1.28−7.26, p = 0.012). Advanced liver fibrosis was associated with an increased rate of SICH and increased 90-day mortality after IV tPA. The FIB-4 score may be useful for prognostication after IV tPA.

Abstract
ABSTRACT BACKGROUND: Endovascular mechanical thrombectomy can improve clinical outcomes in eligible patients with acute ischemic stroke (AIS), but its efficacy is time dependent. This quality improvement project aimed to examine whether a revised evidence-based neurological deficit algorithm initiated in the emergency department could reduce door-to-groin puncture time to less than 90 minutes and improve neurological outcomes in AIS patients who received mechanical thrombectomy. METHODS: Retrospective chart reviews occurred between September 2020 and April 2021, which included 25 patients. Clinical and time data were collected from AIS patients who were 18 years and older, presented for care with AIS symptoms, and deemed candidates for thrombectomy for a period of 6 months. A revised neurological deficit algorithm was initiated, and education was presented to appropriate staff. Postintervention chart reviews occurred from August 2021 to January 2022, which included 25 patients. RESULTS: Door-to-groin puncture time did not improve to less than 90 minutes; however, there was a slight improvement in time from 106 minutes in the preintervention to 98 minutes in the postintervention (P = .534). Although the outcome measures were not clinically significant, there was a statistically significant decrease in response time to acute stroke call down (P < .01). Door-to-computed tomography also improved, which was 14.42 minutes for the preintervention group and 5.25 minutes for the postintervention group (P < .001). Finally, the mean National Institutes of Health Stroke Scale on discharge for the preintervention group was 11.92, and that of the postintervention group was 6.05 on discharge (P < .01). CONCLUSIONS: Implementation of the revised neurological deficit algorithm did not decrease the door-to-groin puncture time to less than 90 minutes. After implementation of the revised neurologic deficit algorithm, there were single variable improvements in several benchmarks, and this is a starting point for future quality improvement projects.

Neurologic outcomes of carotid and other emergent interventions for ischemic stroke over six years with dataset enhanced by machine learning. J Vasc Surg 2022; 76:1280-1288.e2. [PMID: 35760242 DOI: 10.1016/j.jvs.2022.06.020] [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: 03/02/2022] [Revised: 06/04/2022] [Accepted: 06/15/2022] [Indexed: 11/21/2022]
Abstract
INTRODUCTION Current mainstays of ischemic stroke treatment include the use of thrombolysis (tissue plasminogen activator, tPA), urgent carotid endarterectomy (uCEA) or carotid artery stenting (uCAS), and mechanical endovascular reperfusion/thrombectomy (MER). Scarce data describe the presenting stroke severity and neurologic outcomes for these acute ischemic stroke interventions, alone or in combination. The authors hypothesize that patients undergoing carotid interventions experience better functional neurologic outcomes than other stroke interventions. METHODS A comprehensive stroke center dataset was combined with data for stroke-related procedures, comorbidities, complications, and physician documentation collected from electronic medical record data. A total of 10,975 patient encounter records from January 1, 2015, through July 31, 2021, were retrieved. The presenting stroke severity was determined by vascular/stroke neurologists using the National Institutes of Health Stroke Scale (NIHSS). Functional neurologic outcomes were reported using the modified Rankin scale (mRS) score which quantifies the degree of neurologic disability. Because mRS values were only available for 3,627 encounters in the original dataset, the authors developed a machine learning algorithm to analyze physician documentation and assign an mRS value. Following exclusion and machine learning analysis, a total of 5,170 patient encounters were included for statistical analysis. Statistical analyses included chi-squared test, one-way ANOVA and logistic regression on 30-day complications, stroke severity, and neurologic outcomes. RESULTS Patients were divided into five cohorts: (1) uCEA or uCAS (n=189), (2) tPA alone (n=1,053), (3) MER alone (n=418), (4) tPA + MER (n=199), and (5) no intervention (n=3,311). Patients undergoing uCEA/uCAS were significantly more likely to be male, smokers, and have a history of peripheral arterial disease compared to other stroke cohorts. The length of stay was shortest for patients who only received tPA or no intervention (6 days), followed by uCEA/uCAS (7.2 days), MER (10.2 days), and tPA + MER (8.8 days) cohorts (P<.001). The 30-day mortality was highest in the MER cohort (12.2%) and lowest in the uCEA/uCAS cohort (2.6%). The uCEA/uCAS cohort compared to other cohorts had the lowest presenting stroke severity (NIHSS 4.9 vs 6.9-16), and best neurologic outcomes (mRS 1.7 vs 1.8-2.6). CONCLUSIONS Following an ischemic stroke, patients undergoing urgent carotid interventions had the lowest presenting stroke severity (NIHSS) and highest rate of independent neurologic outcomes (mRS) compared to other stroke interventions. Incoming stroke severity correlates with functional neurologic outcomes, and patients who present with an NIHSS ≤ 10 who undergo uCEA/uCAS have a high likelihood of independent neurologic functional outcome (mRS ≤2).

Abstract
Stroke is the second leading cause of death worldwide. One of the main causes of stroke is carotid artery stenosis. Stenosis with atherosclerosis in the carotid artery can cause stroke by hemodynamic ischemia or artery to artery embolism. A most common surgical intervention for carotid artery stenosis is carotid endarterectomy (CEA). Many studies on CEA have been reported and suggested medical indications. For symptomatic carotid stenosis, generally, CEA may be indicated for patients with more than 50% stenosis and is especially beneficial in men, patients aged 75 years or older, and patients who underwent surgery within 2 weeks of their last symptoms. For asymptomatic carotid stenosis, CEA may be indicated for those with more than 60% stenosis, though each guideline has different suggestions in detail. In order to evaluate the indication for CEA in each case, it is important to assess risks for CEA carefully including anatomical factors and comorbidities, and to elaborate each strategy for each operation based on preoperative imaging studies including carotid ultrasonography, magnetic resonance imaging and angiography. In surgery there are many tips on operative position, procedure, shunt usage and monitoring to perform a safe and smooth operation. Now that carotid artery stenting has been rapidly developed, better understanding for CEA is required to treat carotid artery stenosis adequately. This chapter must be a good help to understand CEA well.

Abstract
OBJECTIVE The aim of present study was to evaluate the prognostic impact of National Institutes of Health Stroke Scale (NIHSS) score in patients undergoing acute CEA, and to assess clinical and morphological factors that could predict worse outcomes. METHODS The data of 183 consecutive patients who have undergone CEA after ischemic stroke was analyzed from January 2015 to January 2021. Patients were divided into two groups using the NIHSS cut off point of 4. Functional dependence was assessed on hospital discharge and 90 days after. RESULTS In total, 102 patients (55.7%) had a minor stroke (Group A: NIHSS ≤ 4), whereas 81 patients (44.3%) had a moderate-major stroke (Group B: NIHSS > 4). Group A and group B showed significant differences in their intracranial anatomic features: presence of incomplete Circle of Willis (7.8% vs 17.3%; p=.05), volume of Cerebral ischemic lesion volume ≥4000 mm3 (5.9 % vs 24.7%; p=<.001), and high ASPECTS of 8 to 10 (75.5% vs 44.4%; p=<.001). The overall rate of combined perioperative stroke/myocardial infarction/death was 1.1%, with no strokes recorded during the waiting time to carotid endarterectomy (CEA). Patients in group A had a lower rate of functional dependence at discharge (4.9% vs. 35.8%; p = <.001) and at 90 days after index stroke event (2.5% vs. 19.6%; p = <.001) versus those in group B. Using multivariate binary logistic regression, admission NIHSS>4 was significantly associated with higher odds of functional dependence at discharge (OR= 7.9, 95%CI= 2.7-18.5, p = <.001) and at 90 days (OR= 10.4, 95%CI= 2.7-19.3, p = .002). CONCLUSIONS NIHSS>4 at admission will increase the risk of having higher mRS scores both at hospital discharge and at 90 days after index stroke event. acute CEA was safe and feasible in patients with ischemic stroke, even if they had previously undergone intravenous thrombolysis.

Abstract
Previous studies demonstrated that diabetic stroke patients had a poor prognosis and excess complement system activation in the peripheral blood. In this study, the association of serum complement levels with the prognosis of diabetic stroke was examined. Patients with acute ischemic stroke were recruited and were divided into two groups according to their history of diabetes. Baseline data on the admission, including C3 and C4 were collected. Neurologic function at discharge was the primary outcome and was quantified by the National Institutes of Health Stroke Scale (NIHSS). A total of 426 patients with acute ischemic stroke (116 diabetic strokes and 310 non-diabetic strokes) were recruited in this study. There were significant differences between the two groups in hypertension, coronary disease, triglyceride, high-density lipoprotein cholesterol, fasting blood sugar, C4, and mortality rates. Furthermore, the values of complement protein levels were divided into tertiles. In the diabetic stroke group, serum C4 level at the acute phase in the upper third was independently associated with NIHSS score at discharge and concurrent infection. These associations were not significant in non-diabetic stroke. High serum C4 level at admission, as a unique significant predictor, was associated with unfavorable clinical outcomes in the diabetic stroke, independently of traditional risk factors.

Abstract
Background Prior studies have shown an increased risk of ischemic stroke (IS) after myocardial infarction (MI); however, there are limited studies concerning the characteristics, in‐hospital mortality, and complications of patients with IS with a medical history of MI. We hypothesized that patients with IS with a medical history of MI may experience more severe strokes and have a higher risk of in‐hospital mortality and complications than patients with IS without a medical history of MI. Methods and Results Consecutive in‐hospital data were extracted from the China Stroke Center Alliance database from August 2015 to July 2019. Patient characteristics, hospital tests, in‐hospital mortality, and complications were analyzed and compared in patients with IS with or without a history of MI. Of 893 429 patients with IS, we identified 81 646 (9.1%) patients with a history of MI (MI group). Compared with patients with IS without MI, MI group patients were older, had a lower prevalence of current smoking, had a higher prevalence of a relative medical history, and took more medications before admission. Compared with the group with IS without MI, the MI group had a higher National Institute of Health Stroke Scale score after onset (4.0 versus 3.0; Hodges‐Lehmann estimator, 22.5) and a higher proportion of severe strokes (National Institute of Health Stroke Scale score ≥15) (7.1% versus 4.4%; absolute standardized difference=11.6%). In the fully adjusted models, the risk of in‐hospital mortality was higher in the MI group (odds ratio [OR], 1.74; 95% CI, 1.57–1.92; P<0.0001). MI group patients also had a higher risk of complications, including urinary tract infection (OR, 1.28; 95% CI, 1.2–1.36; P<0.0001), gastrointestinal bleeding (OR, 1.29; 95% CI, 1.19–1.39; P<0.0001), pneumonia (OR, 1.24; 95% CI, 1.21–1.28; P<0.0001), depression (OR, 1.33; 95% CI, 1.24–1.42; P<0.0001), seizure (OR, 1.35; 95% CI, 1.22–1.49; P<0.0001), atrial fibrillation (OR, 1.78; 95% CI, 1.71–1.86; P<0.0001), and cardiac or respiratory arrest (OR, 1.98; 95% CI, 1.78–2.2; P<0.0001). Conclusions Patients with IS with a medical history of MI have an increased risk of severe stroke, in‐hospital mortality, and complications. Studies exploring the underlying mechanisms are needed to improve and tailor stroke treatment strategies.

A Systematic Review Supporting the Society for Vascular Surgery Guidelines on the Management of Carotid Artery Disease. J Vasc Surg 2021; 75:99S-108S.e42. [PMID: 34153350 DOI: 10.1016/j.jvs.2021.06.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Accepted: 06/01/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND To support the development of guidelines on the management of carotid disease, a writing committee from the Society for Vascular Surgery has commissioned this systematic review. METHODS We searched multiple data bases for studies addressing 5 questions: medical management vs. carotid revascularization (CEA) in asymptomatic patients, CEA vs. CAS in symptomatic low surgical risk patients, the optimal timing of revascularization after acute stroke, screening high risk patients for carotid disease, and the optimal sequence of interventions in patients with combined coronary and carotid disease. Studies were selected and appraised by pairs of independent reviewers. Meta-analyses were performed when feasible. RESULTS Medical management compared to carotid interventions in asymptomatic patients was associated with better early outcome during the first 30 days. However, CEA was associated with significantly lower long-term rate of stroke/death at 5 years. In symptomatic low risk surgical patients, CEA was associated with lower risk of stroke, but a significant increase in MI compared to CAS during the first 30 days. When the long-term outcome of transfemoral CAS vs. CEA in symptomatic patients were examined using pre-planned pooled analysis of individual patient data from four randomized trials, the risk of death or stroke within 120 days of the index procedure was 5.5% for CEA and 8.7% for CAS, which lends support that over the long-term, CEA has superior outcome than transfemoral CAS. When managing acute stroke, the comparison of CEA during the first 48 hours to that between day 2 and day14 did not reveal a statistically significant difference on outcomes during the first 30 days. Registry data show good results with CEA performed in the first week, but not within the first 48 hours. A single risk factor, aside from PAD, was associated with low carotid screening yield. Multiple risk factors greatly increase the yield of screening. Evidence on the timing of interventions in patients with combined carotid and coronary disease was sparse and imprecise. Patients without carotid symptoms, who had the carotid intervention first, compared to a combined carotid intervention and CABG, had better outcomes. CONCLUSIONS This updated evidence summary will support the SVS clinical practice guidelines for commonly raised clinical scenarios. CEA was superior to medical therapy in long-term prevention of stroke/death over medical therapy. CEA was also superior to transfemoral CAS in minimizing long-term stroke/death for symptomatic low risk surgical patients. CEA should optimally be performed between 2-14 days from the onset of acute stroke. Having multiple risk factors increases the value of carotid screening.

Abstract
OBJECTIVE This study examined the clinical features, functional outcomes, and prognostic indicators of acute ischemic stroke (AIS) patients who had an Alberta Stroke Program Early Computed Tomography Score (ASPECTS) ≤ 5 and who underwent mechanical thrombectomy (MT). METHODS We included consecutive AIS patients with ASPECTS ≤ 5 who had received MT at the same hospital. Demographic, clinical, and radiological data were collected and analyzed. Functional outcome at 90 days after treatment was classified as good or poor based on the modified Rankin Scale (mRS). RESULTS Of the 152 included patients with ASPECTS ≤ 5 who received MT, 64 (42.11%) experienced poor functional outcomes and 32 (21.1%) experienced good functional outcomes. The independent predictors of poor functional outcomes were the presence of respiratory tract infections (OR 3.72, 95% CI 1.17-11.91), modified thrombolysis in cerebral infarction (OR 0.41, 95% CI 0.2-0.83), symptomatic intracerebral hemorrhage (sICH) (OR 4.96, 95% CI 1.36-18.13), and baseline score on the National Institute of Health Stroke Scale (NIHSS) (OR 1.18, 95% CI 1.03-1.36). Independent predictors of 90-day mortality included time from groin puncture to recanalization (OR 1.03, 95% CI 1.01-1.05), NIHSS scores (OR 1.28, 95% CI 1.12-1.47) and the occurrence of sICH (OR 1.81, 95% CI 1.25-5.75). CONCLUSION AIS patients with ASPECTS ≤ 5 can experience good functional outcomes after MT. However, patients with sICH, respiratory infection, higher NIHSS score or failed recanalization are more likely to experience poor functional outcomes.

Abstract
OBJECTIVE Symptomatic carotid artery stenosis needs revascularization within 2 weeks by carotid endarterectomy (CEA) to reduce the risk of symptom recurrence; however, the optimal timing of intervention is yet to be defined in patients with large-volume cerebral ischemic lesion (LVCIL) and modified Rankin scale (mRS) score ≥3. The aim of this study was to determine the most appropriate timing for CEA in patients with a recent stroke and LVCIL. METHODS Data from patients with symptomatic carotid stenosis with LVCIL and mRS score of 3 or 4 from 2007 to 2017 were considered. Patients were submitted to CEA if they had a stable clinical condition and life expectancy >1 year. LVCIL was defined as a cerebral ischemic lesion of volume >4000 mm3. Perioperative stroke and death were evaluated by stratifying for timing of CEA by χ2 test and multiple logistic regression. Patients with similar characteristics (LVCIL and mRS score of 3 or 4) unfit for CEA served as the control group for recurrence of stroke at 1-year follow-up. RESULTS In an 11-year period, of a total 4020 CEAs, 126 (2.9%) were performed in patients with a moderate stroke and LVCIL occurring in the same admission. The patients' median age was 69 years (interquartile range [IQR], 10 years); 72% (91) were male, with mRS score of 3 (IQR, 1) and LVCIL volume of 20,000 mm3 (IQR, 47,000 mm3). The median time elapsed from symptoms to CEA was 7 weeks (IQR, 8 weeks). Overall perioperative stroke/death was 7.3% (eight strokes and one death). By selective timing evaluation of the postoperative events, CEA performed within 4 weeks was associated with a significantly higher rate of stroke/death compared with patients operated on after 4 weeks: 11.9% (8/67) vs 1.7% (1/59; P = .03). By logistic regression, CEA within 4 weeks was an independent (from sex, cerebral ischemic lesion volume, dyslipidemia, and carotid stenosis) predictor of postoperative stroke/death (odds ratio, 8.2; 95% confidence interval, 1.01-73). In the same period, 101 patients were considered unfit for CEA for dementia (n = 22), severe comorbidities (n = 55), or short (<1-year) life expectancy (n = 24), and 43 (43%) survived at 1 year. At 1 year, the perioperative/recurrent stroke after CEA vs patients unfit for CEA was similar (6.2% vs 13.9%; P = .11), but CEA performed after 4 weeks led to significantly lower perioperative/recurrent stroke (1.7% vs 13.9%; P = .02). CONCLUSIONS The surgical risk of CEA in patients with a recent moderate-severe ischemic stroke and LVCIL is high. However, if the intervention is delayed >4 weeks, its benefit seems significant.

Background and aims The structured, simplified modified Rankin scale questionnaire (smRSq) may increase reliability over the interrogative approach to scoring the modified Rankin scale (mRS) in acute stroke research and practice. During the conduct of the alteplase-dose arm of the international ENhanced Control of Hypertension ANd Thrombolysis StrokE stuDy (ENCHANTED), we had an opportunity to compare each of these approaches to outcome measurement. Methods Baseline demographic data were recorded together with the National Institutes of Health Stroke Scale (NIHSS). Follow-up measures obtained at 90 days included mRS, smRSq, and the 5-Dimension European Quality of life scale (EQ-5D). Agreements between smRSq and mRS were assessed with the Kappa statistic. Multiple logistic regression was used to identify baseline predictors of Day 90 smRSq and mRS scores. Treatment effects, based on Day 90 smRSq/mRS scores, were tested in logistic and ordinal logistic regression models. Results SmRSq and mRS scores had good agreement (weighted Kappa 0.79, 95% confidence interval (CI) 0.78–0.81), while variables of age, atrial fibrillation, diabetes mellitus, pre-morbid mRS (1 vs. 0), baseline NIHSS scores, and imaging signs of cerebral ischemia, similarly predicted their scores. Odds ratios for death or disability, and ordinal shift, 90-day mRS scores using smRSq were 1.05 (95% CI 0.91–1.20; one-sided P = 0.23 for non-inferiority) and 0.98 (95% CI 0.87–1.11; P = 0.02 for non-inferiority), similar to those using mRS. Conclusions This study demonstrates the utility of the smRSq in a large, ethnically diverse clinical trial population. Scoring of the smRSq shows adequate agreement with the standard mRS, thus confirming it is a reliable, valid, and useful alternative measure of functional status after acute ischemic stroke.

Abstract
Acute ischemic strokes (AIS) with severe neurologic deficits are associated with poor short- and long-term prognosis. Thrombectomy alone or in combination with thrombolysis is used for reperfusion in patients with moderate-to-severe AIS. However, the best therapeutic approach within the setting of telemedicine networks needs to be elucidated further. The objective of this study was to analyze clinical and imaging based outcomes of moderate to severe stroke following treatment with thrombolysis, thrombectomy or a combination of both in a telemedicine network. Data of this retrospective study was abstracted from the institutional telestroke database. Patients with a National Institute of Health Stroke Scale score (NIH-SS ≥ 10) were included into the study. Primary outcome measure was the difference in NIH-SS at admission compared to discharge from the hospital. Secondary outcome measure was the discharge disposition defined as favorable (discharge to home or rehabilitation) versus unfavorable disposition (discharge to hospice/death). Furthermore, outcome was analyzed based on reperfusion status following thrombectomy using the Thrombolysis in Cerebral Infarction (TICI) scale. The NIH-SS improved in all three groups, independent of treatment subtype, with a trend towards best outcomes following thrombolysis and combined treatment therapy compared to thrombectomy alone. In addition, reperfusion rates were higher in the combination group compared to the thrombectomy only group. The number of favorable discharges was similar in all three groups. The present study stresses the benefits of tele-stroke networks in allowing to early identify and treat even patients with severe strokes and benefit from different treatment modalities.
