Taking a daily aspirin to prevent heart disease is no longer a blanket recommendation. Upstate cardiologist Robert Carhart, MD, tells about new guidelines from the American College of Cardiology and the American Heart Association that address the best ways to prevent heart disease. He explains how some patients who are at higher risk may still be advised to take aspirin, typically a baby aspirin per day. The guidelines also address physical activity, diet, tobacco use, diabetes, cholesterol and high blood pressure. Carhart tells what people can do to lower their risk of developing heart disease.
