Post-Surgery Abnormal Heart Rhythm Linked to Increased Stroke Risk

A large new study has linked post-surgery atrial fibrillation to a significant increase in risk of future stroke. According to an article published in the New York Times’ Well Blog, the study, published in the Journal of the American Medical Association, followed 1.7 million patients who did not have a diagnosis of atrial fibrillation before surgery, and found that 25,000 developed the condition afterwards. Of those affected, patients who experienced episodes of abnormal heart rhythm after cardiovascular surgery had a 30 percent increase in risk of stroke, while those who developed it after other surgeries doubled their risk.
