Heart Attack: After Your Visit
Your Care Instructions
A heart attack (myocardial infarction, or MI) occurs when one or more of the coronary arteries, which supply the heart with oxygen-rich blood, is blocked. A blockage usually occurs when plaque inside the artery breaks open and a blood clot forms in the artery.
After a heart attack, you may be worried about your future. Over the next several weeks, your heart will start to heal. Although it is sometimes hard to break old habits, you can prevent another heart attack by making some lifestyle changes and by taking medicines. You may use the following information for ideas about what to do at home to speed your recovery.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It’s also a good idea to know your test results and keep a list of the medicines you take.
How can you care for yourself at home?
- Increase your activities slowly. Take short rest breaks when you get tired.
- If your doctor recommends it, get more exercise. Walking is a good choice. Bit by bit, increase the amount you walk every day. Try for at least 30 minutes on most days of the week. You also may want to swim, bike, or do other activities. Talk with your doctor before you start an exercise program to make sure it is safe for you.
- If your doctor has not set you up with a cardiac rehabilitation (rehab) program, talk to him or her about whether that is right for you. Cardiac rehab includes supervised exercise, help with diet and lifestyle changes, and emotional support. It may reduce your risk of future heart problems.
- Do not drive until your doctor says you can.
- You can have sex as soon as you feel ready for it. Often this means when you can easily walk around or climb stairs. Talk with your doctor if you have any concerns. Do not take sildenafil citrate (Viagra), tadalafil (Cialis), or vardenafil (Levitra) if you are taking nitroglycerin.
- Do not smoke. Smoking increases your risk of another heart attack. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
- Eat a heart-healthy diet that is low in cholesterol, saturated fat, and salt, and is full of fruits, vegetables and whole-grains. Eat at least two servings of fish each week. You may get more details about how to eat healthy, but these tips can help you get started.
- Avoid colds and flu. Get a pneumococcal vaccine shot. If you have had one before, ask your doctor whether you need a second dose. Get the flu vaccine every fall. If you must be around people with colds or flu, wash your hands often.
- Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine. You will get more details on the specific medicines your doctor prescribes. You may need several medicines.
- Angiotensin-converting enzyme (ACE) inhibitors, beta-blockers, and statins can help prevent another heart attack. ACE inhibitors control your blood pressure, and statins help lower cholesterol.
- Aspirin and other blood thinners help prevent blood clots. Blood clots can cause a stroke or heart attack.
- If your doctor has given you nitroglycerin, keep it with you at all times. If you have angina symptoms, such as chest pain, sit down and rest, and take the first dose of nitroglycerin as directed. If symptoms get worse or are not getting better within 5 minutes, call 911 immediately. Stay on the phone with the emergency operator; he or she will give you further instructions.
- Be sure to tell your doctor about any angina symptoms, such as chest pain, you have had, even if they went away.
- Do not take any over-the-counter medicines, vitamins, or herbal products without talking to your doctor first.
- Talk to your family, friends, or a counselor about your feelings. It is normal to feel frightened, angry, hopeless, helpless, and even guilty. Talking openly about bad feelings can help you cope. If you have symptoms of depression, talk to your doctor.
When should you call for help?
Call 911 anytime you think you may need emergency care. For example, call if:
