Mild exercise prevents atrial fibrillation in seniors

Just walking a few short blocks can make a big difference in heart health for the elderly. A recent study found that light exercise such as walking or dancing can prevent atrial fibrillation.

Atrial fibrillation is a common heart condition where the upper chambers of the heart twitch instead of beating steadily. The condition is most common in people over age 65, though there is an elevated number of cases in younger people who exercise vigorously (e.g. marathon runners).

The researchers studied the lifestyle habits of more than 5,000 people (average age of 73) and found that those who were active had a reduced risk of the heart condition. In fact, those who walked five to 11 blocks a week had 22% less risk of developing the condition.
