Background: Peripheral arterial disease (PAD) is frequently present in patients with acute ischemic stroke. However, there are limited data regarding the association between ankle brachial index (ABI) ≤ 0.90 (which is diagnostic of PAD) or > 1.40 (suggesting calcified arteries) and the severity of stroke and in-hospital outcome in this population. We aimed to evaluate these associations in patients with acute ischemic stroke. Patients and methods: We prospectively studied 342 consecutive patients admitted for acute ischemic stroke (37.4 % males, mean age 78.8 ± 6.4 years). The severity of stroke was assessed with the National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS) at admission. The outcome was assessed with the mRS and dependency (mRS 2 - 5) at discharge and in-hospital mortality. Results: An ABI ≤ 0.90 was present in 24.6 % of the patients whereas 68.1 % had ABI 0.91 - 1.40 and 7.3 % had ABI > 1.40. At admission, the NIHSS score did not differ between the 3 groups (10.4 ± 10.6, 8.3 ± 9.3 and 9.3 ± 9.4, respectively). The mRS score was also comparable in the 3 groups (3.6 ± 1.7, 3.1 ± 1.8 and 3.5 ± 2.3, respectively). At discharge, the mRS score did not differ between the 3 groups (2.9 ± 2.2, 2.3 ± 2.1 and 2.7 ± 2.5, respectively) and dependency rates were also comparable (59.5, 47.6 and 53.3 %, respectively). In-hospital mortality was almost two-times higher in patients with ABI ≤ 0.90 than in patients with ABI 0.91 - 1.40 or > 1.40 but this difference was not significant (10.9, 6.6 and 6.3 %, respectively). Conclusions: An ABI ≤ 0.90 or > 1.40 does not appear to be associated with more severe stroke or worse in-hospital outcome in patients with acute ischemic stroke.

Background: Clopidogrel reduces the risk of non-cardioembolic ischemic stroke, but it is unclear whether it affects the severity and outcome of stroke. We aimed at evaluating the effect of prior treatment with clopidogrel on acute non-cardioembolic ischemic stroke severity and in-hospital outcome. Methods: We prospectively studied 608 consecutive patients (39.5% males, age 79.1 ± 6.6 years) who were admitted with acute ischemic stroke. The severity of stroke was assessed at admission with the National Institutes of Health Stroke Scale (NIHSS). Severe stroke was defined as NIHSS ≥21. The outcome was assessed using the dependency rates that prevailed at the time of discharge (i.e. modified Rankin scale between 2 and 5) and with in-hospital mortality. Results: At admission, 397 patients did not have atrial fibrillation or heart valve disease. Among these 397 patients, 69 were receiving monotherapy with clopidogrel prior to stroke, 69 were receiving monotherapy with aspirin and 236 patients were not on any antiplatelet treatment. The prevalence of severe stroke was lower in patients who were receiving clopidogrel than in patients who were receiving aspirin and patients who were not on antiplatelets (1.4, 13.0 and 11.0%, respectively; p < 0.05). Independent predictors of severe stroke at admission were male gender (relative risk (RR) 0.31, 95% CI 0.12-0.78, p < 0.05) and treatment with clopidogrel prior to stroke compared with no antiplatelet treatment (RR 0.13, 95% CI 0.02-0.97, p < 0.05). Treatment with aspirin prior to stroke did not predict severe stroke compared with no antiplatelet treatment (RR 1.24, 95% CI 0.51-2.98, p = NS). The rate of dependency at discharge did not differ between patients who were receiving clopidogrel, patients who were receiving aspirin and those who were not on antiplatelets (57.9, 47.8 and 59.7%, respectively; p = NS). Independent predictors of dependency at discharge were age (RR 1.12, 95% CI 1.05-1.19, p < 0.001) and NIHSS at admission (RR 1.67, 95% CI 1.46-1.92, p < 0.001). In-hospital mortality rate also did not differ between patients who were receiving clopidogrel, patients who were receiving aspirin and those who were not on antiplatelets (4.3, 4.3 and 5.0%, respectively; p = NS). The only independent predictor of in-hospital mortality was NIHSS at admission (RR 1.22, 95% CI 1.14-1.30, p < 0.001). Conclusions: Treatment with clopidogrel prior to acute non-cardioembolic ischemic stroke attenuates the severity of stroke at admission but does not appear to affect the functional outcome at discharge or the in-hospital mortality of these patients.

Background: Prior diagnosis of heart failure (HF) is associated with increased length of hospital stay (LOS) and mortality from Coronavirus disease-2019 (COVID-19). Associations between substance use, venous thromboembolism (VTE), or peripheral arterial disease (PAD) and its effects on LOS or mortality in patients with HF hospitalized with COVID-19 remains unknown. Objective: This study identified risk factors associated with poor in-hospital outcomes among patients with HF hospitalized with COVID-19. Methods: Case control study was conducted of patients with prior diagnosis of HF hospitalized with COVID-19 at an academic tertiary care center from January 1, 2020 to February 28, 2021. Patients with HF hospitalized with COVID-19 with risk factors were compared with those without risk factors for clinical characteristics, length of stay (LOS), and mortality. Multivariate regression was conducted to identify multiple predictors of increased LOS and in-hospital mortality in patients with HF hospitalized with COVID-19. Results: Total of 211 HF patients were hospitalized with COVID-19. Females had longer LOS than males (9 days vs. 7 days; p < 0.001). Compared with patients without peripheral arterial disease (PAD) or ischemic stroke, patients with PAD or ischemic stroke had longer LOS (7 days vs. 9 days; p = 0.012 and 7 days vs. 11 days, p < 0.001; respectively). Older patients (aged 65 and above) had increased in-hospital mortality compared to younger patients (Adjusted OR: 1.04; 95% CI: 1.00-1.07; p = 0.036). VTE increased mortality more than three-fold in patients with HF hospitalized with COVID-19 (Adjusted OR: 3.33; 95% CI: 1.29-8.43; p = 0.011). Conclusion: Vascular diseases increase LOS and mortality in patients with HF hospitalized with COVID-19.

Abstract Background Peripheral artery disease (PAD) can be an important predictor of comorbid cerebrovascular disease (CVD). However, it is not sufficiently investigated or considered in the management and prevention of stroke. Objectives To study the prevalence of peripheral arterial disease in large artery ischemic stroke patients and its impact on prognosis. Methods This is a prospective cohort study. A total of 100 patients with large artery ischemic stroke were enrolled with assessment for signs of PAD; duplex on both lower limb arteries and measurement of ankle-brachial index (ABI), carotid duplex, and/or C.T angiography brain and neck and/or conventional angiography; functional assessment by NIHSS at days 0, 7, and 30; and follow-up for recurrence or death after 6 months. Results Peripheral arterial disease was found in 42% of cases. Fifty percent of patients with lower extremity arterial disease were asymptomatic. Fifty percent had significant carotid stenosis (stenosis > 50%), and 48% of patients with significant carotid stenosis had peripheral arterial disease. During our study, 8 cases had a recurrence of large artery ischemic stroke, and 5 cases (62.5%) had PAD. The recurrence rate of stroke was the highest in the asymptomatic PAD group with 19%. Conclusion The prevalence of PAD in large artery ischemic stroke patients is high. Asymptomatic PAD has a risk potential for large artery ischemic stroke recurrence and mortality more than symptomatic PAD and non-PAD patients.

Summary. Background: Theoretically progressive compression stockings, which produce a higher compression at the calf than at the ankle level, improve venous return flow without exacerbating peripheral arterial insufficiency (PAD). We aimed to evaluate the short-term tolerance of elastic progressive compression stockings on peripheral arterial vascularisation in patients with symptomatic PAD and associated mild venous insufficiency. Patients and methods: Monocentric, prospective, open pilot study of 18 patients (acceptability study, 6 x 6 plan) evaluating the short-term tolerance of progressive compression stockings (18 ± 2 mmHg at calf and 8 ± 2 mmHg at ankle level) in patients with PAD (ankle brachial index ABI > 0.60 < 0.75) and chronic venous insufficiency (C1s–C4 stages of the CEAP classification). Day 15 tolerance was evaluated by a composite primary criteria comprising: no decrease > 15 % of ABI on each side, no decrease > 15 % of toe brachial index (TBI) on each side and no decrease > 25 % of the number of active plantar flexions performed while standing. Results: The proportion of men was 77.8 %, mean age was 77.3 ± 7.5 years and no patient were diabetic. At inclusion, the mean low ABI was 0.60 ± 0.04 and the mean high ABI was 0.77 ± 0.18. The mean low TBI was 0.32 ± 0.09 and the mean high TBI 0.46 ± 0.15. The mean number of active standing plantar flexions was 33.0 ± 5.0. The majority of the patients were classified in CEAP C2s and C3 classes (class 2: 16.7 %, class C2s: 27.8 %, class C3: 44.4 %, class C4: 5.6 % and class C4s: 5.6 %). Poor tolerance occurred in no patient. By day 30, no patient had worsening of their arterial and venous symptoms. No adverse events occurred during the study. Conclusions: These results suggest a high tolerance of progressive elastic stockings (18 ± 2 mmHg at calf and 8 ± 2 mmHg at ankle level) in symptomatic PAD.

OBJECTIVEMechanical thrombectomy using a Solitaire stent retriever has been widely applied as a safe and effective method in adult acute ischemic stroke (AIS). However, due to the lack of data, the safety and effectiveness of mechanical thrombectomy using a Solitaire stent in pediatric AIS has not yet been verified. The purpose of this study was to explore the safety and effectiveness of mechanical thrombectomy using a Solitaire stent retriever for pediatric AIS.METHODSBetween January 2012 and December 2017, 7 cases of pediatric AIS were treated via mechanical thrombectomy using a Solitaire stent retriever. The clinical practice, imaging, and follow-up results were reviewed, and the data were summarized and analyzed.RESULTSThe ages of the 7 patients ranged from 7 to 14 years with an average age of 11.1 years. The preoperative National Institutes of Health Stroke Scale (NIHSS) scores ranged from 9 to 22 with an average of 15.4 points. A Solitaire stent retriever was used in all patients, averaging 1.7 applications of thrombectomy and combined balloon dilation in 2 cases. Grade 3 on the modified Thrombolysis In Cerebral Infarction scale of recanalization was achieved in 5 cases and grade 2b in 2 cases. Six patients improved and 1 patient died after thrombectomy. The average NIHSS score of the 6 cases was 3.67 at discharge. The average modified Rankin Scale score was 1 at the 3-month follow-up. Subarachnoid hemorrhage after thrombectomy occurred in 1 case and that patient died 3 days postoperatively.CONCLUSIONSThis study shows that mechanical thrombectomy using a Solitaire stent retriever has a high recanalization rate and excellent clinical prognosis in pediatric AIS. The safety of mechanical thrombectomy in pediatric AIS requires more clinical trials for confirmation.
