If You Think You’re Having a Heart Attack at Home: What to Do Immediately
A heart attack is a medical emergency. There is no guaranteed 10-second trick that can stop a heart attack, but taking the right actions quickly can improve your chances of survival.
1. Call emergency services immediately
- Call your local emergency number (for example, 112/911 depending on your location).
- Do not try to drive yourself to the hospital.
2. Sit down and stay as calm as possible
- Stop activity.
- Sit upright or in a comfortable position.
- Loosen tight clothing.
3. Take aspirin only if appropriate
- If emergency operators or a healthcare professional advise it, and you are not allergic, not on a doctor’s restriction against aspirin, and not having signs of serious bleeding, chewing an aspirin may be recommended in some situations.
- Do not delay calling emergency services to take medication.
4. If you are alone
- Unlock the door if you can.
- Keep your phone nearby.
- Alert someone nearby if possible.
Warning signs of a heart attack can include:
- Chest pressure, squeezing, fullness, or pain
- Pain spreading to the arm, jaw, back, or shoulder
- Shortness of breath
- Cold sweat
- Nausea or vomiting
- Sudden weakness or lightheadedness
Some people—especially older adults and people with diabetes—may have less typical symptoms, such as unusual fatigue, indigestion-like discomfort, or shortness of breath.
If someone else collapses:
- Call emergency services.
- Start CPR if they are not breathing normally.
- Use an automated external defibrillator (AED) if available.
Bottom line: The most important “first step” is getting emergency help immediately. Fast treatment can save heart muscle and lives.
