Heart attacks are a leading cause of death, with one occurring every 40 seconds in the United States. A viral claim circulating online suggests vigorous coughing can help survive a heart attack while waiting for medical assistance. But cardiologists are unanimous: this is a dangerous myth with no scientific backing.
The Origin of the Claim
The idea stems from an unverified tip supposedly from a CPR instructor, advising repeated, forceful coughing during a heart attack. The logic, as presented online, claims deep breaths oxygenate the lungs while coughing physically squeezes the heart, restoring blood flow. However, this reasoning is flawed.
Why Coughing Doesn’t Work
Cardiologists confirm that coughing does not treat a heart attack. A heart attack is caused by a blockage in blood flow to the heart, usually a clot. Coughing cannot dissolve clots, restore circulation, or prevent muscle damage. According to Dr. James Udelson of Tufts Medical Center, the claim is unsupported by any medical society like the American Heart Association, which has actively debunked it.
The myth’s danger lies in potentially delaying crucial medical attention. “The longer you wait, the bigger the heart attack,” Dr. Udelson emphasizes.
What You Should Do During a Heart Attack
If you suspect a heart attack, call 911 immediately. Do not attempt to drive yourself to the hospital, as cardiac arrest can occur en route. The American Heart Association recommends calling emergency services first, even if unsure. Women, in particular, may experience atypical symptoms like shortness of breath or jaw pain and should seek help without hesitation.
If available, taking an aspirin while waiting for help is acceptable. Otherwise, remain calm, sit or lie down, and avoid exertion.
“Coughing doesn’t stop a heart attack. Early activation of emergency care is the most effective way to save heart muscle—and lives,” states Dr. Navjot Sobti.
Delaying treatment based on false advice can have deadly consequences. When it comes to a heart attack, prompt professional medical intervention remains the only proven solution.
