Why is exercise so important after a heart attack?

Exercise is good for your heart muscle and overall health. It can help you lose weight, keep your cholesterol and blood pressure under control, reduce stress, and lift your mood. If you participate in a cardiac rehabilitation program, you will learn how to exercise safely and regularly to strengthen your heart and body. When exercising, you will need to watch out for signs of problems such as chest pain, shortness of breath, feeling dizzy or weak, irregular heartbeats, or cold sweats. If you develop these symptoms, stop exercising and call 911 for help right away.
