Cough CPR: What it is and isn't

You may have heard the claim that coughing can stop or prevent a heart attack. This widely shared advice, often called “cough CPR,” is a misunderstood and potentially dangerous myth when applied outside of a hospital setting.

“Cough CPR” is not a treatment for a typical heart attack. It was originally used in very specific, highly controlled medical environments, such as a cardiac catheterization lab, where a patient’s heart rhythm is continuously monitored on an EKG. In rare cases, trained medical professionals may instruct a patient to cough if they develop a sudden, life-threatening heart rhythm while under direct supervision.

Outside of these settings, “cough CPR” does not work and will not save a life.

More importantly, this technique is not endorsed or taught by the American Heart Association (AHA) or any major health organization for public use. It should never be attempted when someone is experiencing a heart attack or cardiac symptoms at home.

Believing this myth can be dangerous. Attempting to cough instead of seeking help can delay critical care, wasting the valuable minutes needed to call 911 and receive life-saving treatment.

Heart attack symptoms can vary, and they don’t always look dramatic. Common warning signs include:

• Chest pain, pressure, tightness, or discomfort
• Pain or discomfort in the arms, back, neck, jaw, or stomach
• Shortness of breath
• Nausea, vomiting, or indigestion-like discomfort
• Cold sweats
• Lightheadedness or dizziness
• Unusual or extreme fatigue (especially in women)

If you or someone near you experiences symptoms of a heart attack:

• Call 911 immediately!
• Do not attempt “cough CPR”
• Chew an aspirin if advised by a medical professional and if not allergic
• Stay calm and still while waiting for emergency responders

When it comes to heart attacks, minutes matter. The safest and most effective response is always to seek emergency medical care right away.
