Cardiac rehabilitation (rehab) teaches you how to be more active and make lifestyle changes that can lead to a stronger heart and better health. Cardiac rehab can help you feel better and reduce your risk of future heart problems. In cardiac rehab, you work with a team of health professionals. Often the team includes a doctor, a nurse specialist, a dietitian, an exercise therapist, and a physical therapist. The team designs a program just for you, based on your health and goals. Then they give you support to help you succeed. If you have had a heart attack, you may be afraid to exercise. Or if you have never exercised, you may not know how to get started. Your cardiac rehab team will help you start slowly and work up to a level that is good for your heart. Doctors often prescribe cardiac rehab for people who have had a heart attack or bypass surgery. But people with many types of heart or blood vessel disease can benefit from cardiac rehab.
