Life After a Heart Attack

If you've already had a heart attack, there are some things you should know.

1. You are at greater risk of having another one.

Talk with your health care team about what to look for – keep in mind a repeat heart attack may or may not feel the same as your first.

Tell your care team if you have chest symptoms that start or get worse with activity and that don’t go away after resting or taking nitroglycerin.

Call 911 if you think you are having symptoms of a heart attack.

2. Follow your care plan.

It's really important to keep up with your treatments – lifestyle changes and medications. There may also be things you should avoid – for example, certain medications, alcohol or foods. Also, know what your ideal weight is, as well as your blood pressure and cholesterol levels.

3. Say 'yes' to cardiac rehabilitation.

Cardiac rehab programs can support your recovery and strengthen your heart. Cardiac rehab programs include supervised exercise training, health education about heart-healthy eating, managing medications, as well as positive coping and mental wellness. Participation in cardiac rehab has been shown to lower the risk of dying or going back to the hospital.

4. Ask for support.

Ask trusted friends and family to help you live a healthier life, come to health visits with you and be there as a source of comfort.

5. Have an emergency plan in place.

Keep a current list of your medications (names, prescriber, dosage and how often you take each), health care professionals with contact information, basic medical history and contact info of a close friend or relative.

If you suspect you are having a heart attack:

  • Stop what you are doing.
  • Rest.
  • Take nitroglycerin if it’s been prescribed. If symptoms continue, call 911.
  • Emergency services personnel will advise you on steps to take and whether you need to chew an aspirin.
