This peer commentary examines clinical outcomes associated with different anticoagulation approaches in patients experiencing ischemic stroke while taking direct oral anticoagulants (DOACs). The response contributes to evidence-based discussion on stroke management strategies in anticoagulated populations.
This systematic review examines FLAIR vessel hyperintensity (FVH), an imaging finding reflecting critically slowed blood flow in large artery steno-occlusions, and its clinical significance for predicting prognosis, stroke severity, infarction volume, and functional outcomes in acute ischemic stroke and TIA. The authors address conflicting findings in the literature and propose key factors for individualizing clinical interpretation of this neuroimaging marker to guide clinical decision-making.
A pharmacoeconomic study evaluated whether personalizing antiplatelet therapy based on CYP2C19 genetic testing (using cilostazol or ticagrelor) is cost-effective compared to standard clopidogrel plus aspirin treatment for minor stroke and high-risk transient ischemic attack in China. The analysis found genotype-guided strategies were cost-effective with incremental cost-effectiveness ratios below accepted thresholds, with robust results across sensitivity analyses.
This study examined cardiac complications in 721 stroke patients across three cerebrovascular event types (ischemic stroke, transient ischemic attack, and hemorrhagic stroke). Results showed ECG changes were most frequent in ischemic stroke (81.7%), with myocardial alterations common across all groups, suggesting important brain-heart interactions following stroke.
This cohort study of 1,808 patients examined whether nocturnal blood pressure dipping patterns predict 1-year functional outcomes after stroke or TIA. While reverse dipping (less than 0% nocturnal systolic BP drop) was associated with worse outcomes in initial analysis, this association became non-significant after adjusting for confounding variables.
