Low exercise capacity is bad news

People who have low exercise capacity when they walk on a treadmill are at increased risk of experiencing a heart event—such as a heart attack—or of dying from one, according to a study published in Archives of Internal Medicine. That’s the conclusion drawn by researchers who conducted treadmill tests on nearly 9,200 adults, then followed them for more than two and a half years. Study subjects whose exercise capacity was lower than those who had normal exercise capacity had more than twice the risk of having a heart attack or chest pain or needing angioplasty or coronary artery bypass surgery. Low exercise capacity was more common in women and in those who also had conditions such as diabetes and high blood pressure.
