Does Inclement Weather Increase the Risk of Cardioembolic Stroke in Kashmir Valley?

Abstract

Background: Cardioembolic strokes are a common cause of mortality and morbidity because they are usually big and multiple. Despite extensive advances in the determination and management of modifiable risk factors of these strokes, a significant proportion are attributed to non-modifiable factors. We wanted to test the hypothesis that cardioembolic strokes and no other subtypes of ischemic stroke are associated with inclement weather in Kashmir Valley where winter seasons have harsh weather. Results: A total of 540 ischemic stroke patients were included in the study of which cardioembolic strokes were most common. Cardioembolic strokes were more common in the winter season and associated with lower minimum and maximum temperatures. Conclusion: Evaluation and management of cardioembolic strokes during winter months may demand more attention, particularly in elderly individuals and those with risk factors for atrial fibrillation.
