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

by
This prompt likely refers to the viral internet myth regarding “Cough CPR”—the claim that if you are having a heart attack alone at home, forcefully coughing every few seconds can save your life.

Medical experts and organizations like the American Heart Association (AHA) warn that this is a dangerous myth.
Here is what you need to know about why that viral advice is wrong, and what you actually should do in a cardiac emergency.

Why “Cough CPR” Does Not Work at Home

  • It’s a clinical procedure, not a home remedy: “Coughing forcefully” is occasionally used in sterile, highly monitored hospital environments (like a cardiac catheterization lab) where doctors watch a patient’s heart rhythm on an EKG and can coach them through a sudden, specific type of abnormal heart rhythm for a matter of seconds.
  • It cannot stop a heart attack: A heart attack is a plumbing problem (a blocked artery cutting off blood flow to the heart muscle). Coughing cannot unblock an artery or cure a heart attack.
  • It wastes critical time: Relying on a breathing or coughing trick instead of calling emergency services wastes precious minutes when professional intervention is required.

What You Should Do Instead (If You Are Alone and Suspect a Heart Attack)

If you experience sudden chest pain, pressure, tightness, shortness of breath, or pain radiating to your arm, jaw, or back, take these steps immediately:
  1. Call Emergency Services: Call your local emergency number (such as 911 or your local ambulance service) right away. Do not try to wait it out or “sleep it off”.
  2. Stop All Activity and Sit Down: Rest immediately to reduce the heart’s demand for oxygen. Sit on the floor or in a comfortable chair, and loosen any tight clothing around your neck or chest.
  3. Take Aspirin (If Safe): If you are not allergic and have not been told by a doctor to avoid it, chew and swallow one regular-strength or adult aspirin (325 mg). Aspirin helps keep blood platelets from clumping together, which can slow down a clot forming in a blocked artery.
  4. Unlock Your Door If Possible: If you live alone, unlock your front door so emergency responders can enter quickly if you lose consciousness.
  5. Do NOT Drive Yourself: Never attempt to drive yourself to the hospital. Call an ambulance so medical care can begin the moment responders arrive.
