Background and Purpose: The aim of the study was to determine the association between previous stroke and mortality after coronavirus disease 2019 (COVID-19) according to sex, age groups, and stroke subtypes. Methods: Prospective population-based cohort study including all COVID-19 positive cases between February 1 and July 31, 2020. Comorbidities and mortality were extracted using linked health administration databases. Previous stroke included transient ischemic attack, ischemic stroke, hemorrhagic stroke, spontaneous subarachnoid hemorrhage, and combined stroke for cases with more than one category. Other comorbidities were obesity, diabetes, hypertension, ischemic heart disease, atrial fibrillation, heart failure, chronic obstructive pulmonary disease, chronic kidney disease, cirrhosis, dementia, individual socioeconomic index, and deprivation index. Cases were followed up until December 31, 2020. Primary outcome was mortality of any cause after COVID-19 positivity. Cox proportional regression analysis adjusted for comorbidities was used. Stratified analyses were performed for sex and age (<60, 60–79, and ≥80 years). Results: There were 91 629 COVID-19 cases. Previous strokes were 5752 (6.27%), of which 3887 (67.57%) were ischemic, 1237 (21.50%) transient ischemic attack, 255 (4.43%) combined, 203 (3.53%) hemorrhagic, and 170 (2.96%) subarachnoid hemorrhage. There were 9512 deaths (10.38%). Mortality was associated with previous stroke (hazard ratio [HR]=1.12 [95% CI, 1.06–1.18], P <0.001), in both sexes separately (men=1.13 [1.05–1.22], P =0.001; women=1.09 [1.01–1.18], P =0.023), in people <60 years (HR=2.97 [1.97–4.48], P <0.001) and 60 to 79 years (HR=1.32 [1.19–1.48], P <0.001) but not in people ≥80 years (HR=1.02 [0.96–1.09], P =0.437). Ischemic (HR=1.11 [1.05–1.18], P =0.001), hemorrhagic (HR=1.53 [1.20–1.96], P =0.001) and combined (HR=1.31 [1.05–1.63], P =0.016) strokes were associated but not transient ischemic attack. Subarachnoid hemorrhage was associated only in people <60 years (HR=5.73 [1.82–18.06], P =0.003). Conclusions: Previous stroke was associated with a higher mortality in people younger than 80 years. The association occurred for both ischemic and hemorrhagic stroke but not for transient ischemic attack. These data might help healthcare authorities to establish prioritization strategies for COVID-19 vaccination.

Background: Evidence about the use of dual antiplatelet therapy (DAPT) with aspirin and P2Y12 inhibitors in patients with acute minor ischemic stroke or transient ischemic attack (TIA) is emerging. The aim of our study was to provide an updated and comprehensive analysis about the risks and benefits of DAPT versus aspirin monotherapy in this setting. Methods: The PubMed, Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov databases, main international conference proceedings were searched for randomized controlled trials comparing DAPT versus aspirin monotherapy in patients with acute ischemic stroke or TIA not eligible for thrombolysis or thrombectomy presenting in the first 24 hours after the acute event. Data were pooled by meta-analysis using a random-effects model. The primary efficacy endpoint was ischemic stroke recurrence, and the primary safety outcome was major bleeding. Secondary endpoints were intracranial hemorrhage, hemorrhagic stroke, and all-cause death. Results: A total of 4 studies enrolling 21,459 patients were included. DAPT with clopidogrel was used in 3 studies, DAPT with ticagrelor in one study. DAPT duration was 21 days in one study, 1 month in one study, and 3 months in the remaining studies. DAPT was associated with a significant reduction in the risk of ischemic stroke recurrence (relative risk [RR], 0.74; 95% confidence interval [CI], 0.67-0.82, P<0.001, number needed to treat 50 [95% CI 40-72], while it was associated with a significantly higher risk of major bleeding (RR, 2.59; 95% CI 1.49-4.53, P=0.001, number needed to harm 330 [95% CI 149-1111]), of intracranial hemorrhage (RR 3.06, 95% CI 1.41-6.66, P=0.005), with a trend towards higher risk of hemorrhagic stroke (RR 1.83, 95% CI 0.83-4.05, P=0.14), and a slight tendency towards higher risk of all-cause death (RR 1.30, 95% CI 0.89-1.89, P=0.16). Conclusions: Among patients with acute minor ischemic stroke or TIA, DAPT, as compared with aspirin monotherapy, might offer better effectiveness in terms of ischemic stroke recurrence at the expense of a higher risk of major bleeding. The trade-off between ischemic benefits and bleeding risks should be assessed in tailoring the therapeutic strategies.

Background and Purpose— We aimed to determine the long-term risks of a motor vehicle collision after a cerebrovascular event and whether the risks were similar after left- or right-hemispheric events. Methods— We used a population-based registry to identify patients diagnosed with a transient ischemic attack or stroke (hemorrhagic or ischemic) between 2003 and 2013 in Ontario, Canada. Hemispheric laterality was determined using radiological and clinical findings. We identified subsequent serious injuries involving the patient as a driver using linked administrative data. Secondary outcomes included serious injuries involving the patient as a pedestrian, as a passenger, or other traumatic events (fall, fracture, ankle sprain). We used proportional hazard models accounting for death as a competing risk to test the association of hemispheric laterality and outcomes with and without adjustment for age, sex, discharge modified Rankin Scale score, home location, and prior driving record. Patients were followed through to 2017. Results— Among 26 144 patients with hemispheric cerebrovascular events, 377 subsequent serious traffic injuries as a driver (2.2 per 1000 person-year) were identified over a median follow-up of 6.4 person-years. The rate did not differ by laterality (adjusted hazard ratio, 1.00; 95% CI, 0.82–1.23). The risk of a serious traffic injury as a pedestrian was significantly higher after a right-sided than left-sided event (adjusted hazard ratio, 1.27; 95% CI, 1.02–1.58). Subsequent risks for other traumatic injuries did not differ by laterality of cerebrovascular event. Conclusions— The risk of a serious traffic injury as a pedestrian is substantially higher after a right-hemispheric cerebrovascular event compared with a left-sided event. Walking should be promoted for exercise in survivors of a stroke or transient ischemic attack, but these vulnerable road users may benefit from additional poststroke rehabilitation to optimize safety.

Background: There is no available estimate of the incidence and mortality of epilepsy in all age groups in the Canadian population. This study aimed to measure the incidence, prevalence, mortality and the secular trends for epilepsy in Saskatchewan between 2005 and 2010. Methods: A population-based cohort study was established from Saskatchewan’s provincial health administrative data. The population was followed until termination of coverage, death, or 31 December 2010. Individuals with epilepsy were identified based on ICD codes algorithms from 2005 to 2010. Results: The age-standardized incidence of epilepsy was 62 per 100,000 person-year. The age-standardized incidence rate of epilepsy in self-declared Registered Indians was 122 per 100,000 person-year. There was a significant decrease in the incidence of epilepsy for all groups over the study period. The age-standardized prevalence of epilepsy was 9 per 1,000 people. There was a significant increase in the prevalence of epilepsy over this time period. The adjusted mortality rate was 0.023 per 1000 person-year, and the all-cause Standardized Mortality Ration for epilepsy was 2.45. The SMR remained constant over the six-year period of the study. Conclusions: This study is the first in Canada to measure the incidence and all-cause mortality of epilepsy in all age groups.

SummaryTo determine the presence of a ‘hypercoagulable state’ as assessed by indices of thrombin and plasmin generation and of the amount of fibrin that is lysed, in patients with stable coronary, cerebral and peripheral arterial disease a population-based cross-sectional study was performed. From a population-based cohort comprising 7983 men and women aged 55 years and over, we randomly selected 127 subjects with a history of myocardial infarction, 124 with a history of stroke and/or transient ischemic attack, 131 patients with peripheral arterial disease and 263 control subjects in the same age group without arterial disease. Subjects using anticoagulant drugs were not selected. F1+2, TAT, and PAP were not associated with a history of cardiovascular events, nor with peripheral arterial disease. In contrast, positive associations were found for D-Dimer. Mean D-Dimer level was 40 μg/l (95% CI 35,44) in control subjects; 53 μg/l (47, 61) in those with a history of myocar-dial infarction and 51 μg/l (45, 58) in those with a history of stroke and or transient ischemic attack. D-Dimer increased gradually with increasing severity of peripheral atherosclerosis; a decrease in ankle/arm systolic blood pressure ratio of 0.1 was associated with an increase in D-Dimer of 3.9 μg/l (p<0.01). This was more pronounced in subjects with higher F1+2, TAT and PAP concentration. In conclusion, the markers of onset of coagulation F1+2, TAT and PAP are not associated with the presence of arterial disease, but increased levels of these markers are necessary for the positive association between D-Dimer and arterial disease.
