Heart attack: First aid

Prevention

Lifestyle changes can keep the heart healthy and may help prevent a heart attack.

  • Don't smoke, use tobacco or vape.
  • Get regular exercise.
  • Keep a healthy weight.
  • Eat healthy foods and use less salt and saturated fats.
  • Limit alcohol.
  • Manage stress.
  • Manage blood pressure, blood sugar and cholesterol.
  • Get 7 to 9 hours of sleep daily.

Also, it's a good idea to learn CPR and how to use an AED so you can help someone who's having a heart attack. Ask your healthcare team if there are any accredited first-aid training courses you can take in your area.
