Stroke; a journal of cerebral circulation

Background and Purpose- Stroke risk is sex-specific, but little is known about sex differences of poststroke major adverse cardiovascular events (MACEs). Stroke-related brain damage causes autonomic dysfunction and inflammation, sometimes resulting in cardiac complications. Sex-specific cardiovascular susceptibility to stroke without the confounding effect of preexisting heart disease constitutes an unexplored field because previous studies focusing on sex differences in poststroke MACE have not excluded patients with known cardiovascular comorbidities. ⋯ First-ever ischemic stroke was associated with increased risk of incident MACE in both sexes. The risk was time-dependent, highest within 30 days (women: adjusted hazard ratio, 25.1 [95% CI, 19.3-32.6]; men: aHR, 23.4 [95% CI, 17.2-31.9]) and decreasing but remaining significant between 31 and 90 days (women: aHR, 4.8 [95% CI, 3.8-6.0]; men: aHR, 4.2 [95% CI, 3.3-5.4]), and 91 to 365 days (aHR, 2.1 [95% CI, 1.8-2.3]; men: aHR, 2.0 [95% CI, 1.7-2.3]). Conclusions- In this large population-based study, ischemic stroke was independently associated with increased risk of incident MACE in both sexes.

Observational Study
Oral Anticoagulation in Asian Patients With Atrial Fibrillation and a History of Intracranial Hemorrhage.
Background and Purpose- Warfarin is associated with a better net clinical benefit compared with no treatment in patients with nonvalvular atrial fibrillation (AF) and history of intracranial hemorrhage (ICH). There are limited data on nonvitamin K antagonist oral anticoagulants (NOACs) in these patients, especially in the Asian population. We aimed to compare the effectiveness and safety of NOACs to warfarin in a large-scale nationwide Asian population with AF and a history of ICH. ⋯ NOAC showed nonsignificant trends toward to reduce fatal ICH compared with warfarin (HR, 0.47 [95% CI, 0.20-1.03]). Conclusions- NOAC was associated with a significant lower risk of ICH and ischemic stroke compared with warfarin. NOAC might be a more effective and safer treatment option for Asian patients with nonvalvular AF and a prior history of ICH.

Background and Purpose- We aimed to further investigate the long-term outcomes after reversible cerebral vasoconstriction syndrome (RCVS). Methods- A longitudinal follow-up study was conducted in 173 RCVS patients. ⋯ After new delivery, the rate of postpartum RCVS was 9%. Conclusions- Overall, long-term outcome after RCVS is excellent.
