The goal is to help you return to an active life, and to reduce the risk of further heart problems. A team of specialists will create a plan for you that includes exercise training, education on heart healthy living, and counseling. You will learn how to reduce your risk factors. These may include disorders such as high blood pressure, high blood cholesterol, overweight or obesity, diabetes. Smoking, lack of physical activity, and depression are other risk factors.
