Following a heart attack, most cardiologists recommend increasing physical activity levels to above what they were before the episode, abstaining from tobacco, and eating a nutritionally balanced diet. It also is important to rest when tired to avoid overexertion. A good night’s sleep and naps may help people who are recovering from a heart attack maintain the energy necessary to maintain their lifestyle changes and stick to a more active routine. Some doctors will recommend starting a physical therapy exercise program or cardiac rehabilitation program to ensure professional supervision and the best results. The length of the program will depend on the specific needs of the individual. Most people who have had a heart attack are able to return to work within a few weeks to a few months, depending on the demands of the job and severity of the attack. A heart attack can be both physically and emotionally taxing, so it’s important to get the psychological help necessary to fully recover. Many people who have had a heart attack feel depressed, angry, resentful, and/or afraid. While these feelings are normal and typically subside in a matter of months, joining a support group or speaking with a professional can help.
