Medical Research: What are the main findings of the study?
Dr. Perez: It was already known that obesity is an important risk factor for atrial fibrillation. We studied over 80,000 postmenopausal women enrolled in the Women’s Health Initiative who were followed for the onset of atrial fibrillation, an irregular heart rhythm associated with stroke and death. We found that those who exercised more than 9 MET-hours/week (equivalent to a brisk walk of 30 minutes six days a week) were 10% less likely to get atrial fibrillation than those who were sedentary. Importantly, the more obese the women were, the more they benefited from the exercise in terms of atrial fibrillation risk reduction.
