Multiple posts shared repeatedly on Facebook claim that coughing vigorously can avert the onset of a heart attack. A similar claim, shared on South Korean social platforms Daum Cafe and Naver Blog, advises people to “keep coughing every two seconds” if they think they are having a heart attack. The claim is false, according to international health experts, who warned the practice could delay life-saving treatment in a health emergency.

The claim was published on Daum Cafe here on February 1, 2021.

Part of the Korean post translates to English as: “What to do when having a heart attack and when alone?

“Don’t be scared and cough vigorously and repeatedly.

“You should keep coughing every two seconds until someone comes to help you or you feel that the condition of your heart has become normalised.”

A similar claim was also shared on Daum Cafe here, here, here; on Facebook here, here and here; and Naver Blog here.

The claim, however, is false, according to health experts.

“There is no medical evidence to support “cough CPR”, which suggests you can help yourself by coughing vigorously if you think you’re having a heart attack and are alone,” Christopher Allen, a BHF coronary care specialist, notes here.

Allen went on to say that the misleading claim circulating on social media is a “myth”, as he urged internet users to “avoid spreading it any further”.

The American Heart Association (AHA) and The National Heart Foundation of Australia also do not endorse “cough CPR.”

“This is the incorrect treatment for a heart attack or cardiac arrest and can delay treatment for saving someone’s life,” the Heart Foundation of Australia states here. “There is no evidence of any benefit of ‘cough CPR’ for heart attack or cardiac arrest.”

The AHA said here that the “best strategy is to be aware of the warning signs for cardiac arrest – sudden loss of responsiveness and no normal breathing – and call 911.”

The Dangerous Truth About Cough CPR

Coughing away a heart attack could delay medical help

The internet is filled with misleading information and the buzzwords “cough CPR” are no different.

The idea of cough CPR has been circulating the web for a few years now and has a slew of misinformation attached to it. The real danger about the misinformation is that it could prevent heart attack victims from getting the lifesaving help they need. Those social media posts claim that by coughing vigorously when you have a heart attack, you can keep yourself from passing out, theoretically saving yourself until your heart starts beating normally again. 

Cardiac surgeon A. Marc Gillinov, MD, and cardiologist Steven Nissen, MD, address the dangerous truth about cough CPR and what you should do instead:

The facts

Heart attacks are not the same thing as cardiac arrest.

“Information regarding cough CPR on social media misleads readers,” says Dr. Gillinov. “This confuses heart attack and sudden cardiac death because they are two different things.”

Heart attacks occur when the heart’s oxygen supply gets cut off, which is usually caused by blockages in the cardiac arteries that feed the heart oxygen-rich blood. When you have a heart attack, tissue in the heart can die. However, your heart usually keeps on beating. Cough CPR is ineffective for heart attacks.

“Cough CPR is an effective way to maintain circulation for a minute or two following cardiac arrest,” says Dr. Nissen. “However, it’s not useful in a patient with a heart attack and shouldn’t delay calling 911.”

When cardiac arrest occurs, unconsciousness and death follow swiftly. Defibrillation is the only way to reliably reset the heart once it has suffered a fatal arrhythmia.

If you see someone collapse following cardiac arrest, call 911 immediately. You can administer approved CPR techniques to keep oxygen circulating to the victim’s brain until medical help arrives.

Cough CPR’s limited use

Coughing violently physically forces blood from the chest up to the brain because of the pressure exerted from the cough. In a clinical setting, patients might be told to cough vigorously during testing, if healthcare professionals detect specific problems. The American Heart Association notes that cough CPR could also be considered in a cardiac catheterization laboratory where the patients are constantly monitored. 

“The bottom line is that cough CPR is not useful outside of a hospital setting,” says Dr. Nissen. 

If you’re experiencing the symptoms of a heart attack, you should immediately call 911. Anyone who loses consciousness following cardiac arrest cannot cough, or even breathe, and needs emergency help.

If you’re witnessing a person having a heart attack, you should immediately call 911 or perform approved CPR rescue while a second bystander calls 911. 

“The most important advice to give is: If you get chest pain or feel faint or feel an irregular heartbeat, call 911,” says Dr. Gillinov.​
