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

by
Viral social media posts frequently claim that if you experience a heart attack while alone at home, you can save your life in 10 seconds by performing forceful, repeated coughing (often called “cough CPR”).

Medical experts and major health organizations, including the American Heart Association, strongly warn that this is a dangerous myth. Coughing forcefully will not stop or treat a heart attack. Relying on this trick is hazardous because it wastes critical seconds and delays emergency medical care.

Why “Cough CPR” is a Dangerous Misconception

  1. Heart Attacks vs. Cardiac Arrest Are Different:
    • A heart attack is a circulation problem where a blocked coronary artery cuts off blood flow to part of the heart muscle. The person is typically conscious, breathing, and their heart is still beating.
    • Cardiac arrest occurs when the heart abruptly stops beating entirely, causing immediate unconsciousness. An unconscious person cannot cough.
  2. Where the Myth Started:
    • In rare, highly controlled hospital environments (such as a cardiac catheterization lab), a doctor or nurse might briefly instruct a fully conscious, continuously monitored patient to cough during a sudden, specific heart rhythm disturbance (arrhythmia) to maintain blood flow to the brain for a few seconds.
    • This technique does not work outside a hospital, does not fix a blocked artery causing a heart attack, and is never a substitute for emergency intervention.

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

If you or someone near you experiences warning signs of a heart attack—such as crushing chest pressure or pain, shortness of breath, sudden cold sweats, nausea, or pain radiating down the arm or jaw—take these proven, life-saving steps right away:
  1. Call Emergency Services (911 or your local emergency number) Immediately: Do not try to wait it out, “sleep it off,” or drive yourself to the hospital. Paramedics can begin life-saving treatment the moment they arrive.
  2. Stop All Exertion and Rest: Sit down or lie down in a comfortable position immediately. Conserve your energy, stay as calm as possible, and avoid unnecessary movement.
  3. Unlock Your Front Door (If Alone): If you can do so safely without overexerting yourself, unlock your front door so emergency responders can enter immediately without delay.
  4. Take Aspirin (If Appropriate): If you are not allergic to aspirin and have no history of bleeding disorders or bleeding stomach ulcers, chewing and swallowing a regular or low-dose aspirin can help prevent blood platelets from clustering around a growing clot while waiting for help.
  5. Use Prescribed Medication: If a doctor has previously prescribed nitroglycerin for heart conditions, take it as directed while waiting for emergency assistance.
