AFib and Stroke: Nearly 1/3 of strokes are caused by AFib1


How are AFib and stroke related?

Stroke is a serious complication of AFib that is associated with long term disability and mortality. Immediately after a stroke, patients with AFib have greater neurologic impairment and functional disability than patients without AFib.2

A stroke occurs when the flow of blood to part of the brain is significantly reduced or blocked.3,4 The most common cause of a stroke is a blood clot (ischemic stroke).


How does stroke impact quality of life?

The occurrence of stroke can have a devastating impact on patient quality of life and the ability to perform daily activities. Stroke can cause significant impairment in physical, psychological, and social function, and can reduce a patient’s ability to carry out routine activities.5,6


How can I reduce my stroke risk?

Talk to an electrophysiologist about ways to reduce your risk of stroke. Some options may include blood thinners, left atrial appendage or catheter ablation. AFib patients treated with catheter ablation experience fewer strokes within three years following treatment, compared to those who did not receive ablation.7
