If you have a heart attack at home, do this in 10 seconds and you can save your life.(1 / 2)

That viral claim—often suggesting that coughing violently and repeatedly can save you during a heart attack when you are alone—is a dangerous myth.

Why the “Cough CPR” Myth is Dangerous

The viral chain message typically advises you to take deep breaths and cough forcefully every two seconds to keep your blood circulating until help arrives.
  • It Does Not Work for Heart Attacks: “Cough CPR” is a real, highly specialized medical technique used only in a controlled hospital setting (such as a cardiac catheterization lab) under direct electrocardiogram (ECG) monitoring, and strictly for a very specific type of abnormal heart rhythm called ventricular tachycardia, where the heart stops pumping effectively for a few seconds.
  • Wasted Critical Seconds: If you are actually experiencing a myocardial infarction (a heart attack caused by a blocked coronary artery), coughing does nothing to clear the blockage or restore blood flow to the heart muscle. Wasting precious seconds trying to cough forcefully can delay the single most important action you need to take: calling for emergency medical help.

What You Should Do If You Suspect a Heart Attack at Home

If you or someone nearby experiences sudden heart attack symptoms (such as crushing chest pain or pressure, pain radiating down the arm or jaw, shortness of breath, sudden cold sweats, or lightheadedness), take these steps immediately:
  1. Call Emergency Services Immediately (e.g., 911): Do not wait to see if the pain passes, and do not try to drive yourself to the hospital. Emergency paramedics can begin lifesaving treatment the moment they arrive.
  2. Chew Aspirin (If Recommended): If you are not allergic and have not been told by a doctor to avoid it, chewing (not just swallowing) an uncoated regular-strength aspirin can help slow blood clotting if the heart attack is caused by a clot.
  3. Sit Down and Rest: Sit on the floor or a comfortable chair to reduce strain on your heart and prevent a dangerous fall if you become dizzy or lose consciousness. Loosen any tight clothing around your neck or chest.
  4. Unlock Your Door: If you are home alone, unlock your front door so emergency responders can enter quickly if you lose consciousness.
