Researchers at Cedars-Sinai Heart Institute reported Sunday at an American Heart Association conference that only one in every 100 cases of sudden cardiac arrest in men occurred after sexual activity. If not treated immediately it can lead to sudden cardiac death, which results in around 350,000 deaths annually in the United States. Chugh's team analyzed 4,557 cardiac arrests that occurred between 2002 and 2015, and found that 34 happened within one hour of sexual intercourse.

The odds that sex will kill you by inducing sudden cardiac arrest are probably lower than 1 percent. "Now we can tell them the risk is very low".

Another study looked at 246 people who had heart attacks in various scenarios and found that those who did during sex fared particularly badly.

Put another way, less than 1 percent of the deaths from sudden cardiac arrest were related to sex.

Those who experienced sexual activity related sudden cardiac arrest tended to be younger, with an average age of 60.3 years, compared to an average age of 65.2 years for those who had a sudden cardiac arrest that wasn't linked to sex.

Only a third of those suffering from cardiac arrest from sex received potentially life-saving CPR-despite the likelihood that a partner was around to witness the arrest. In most cases they were middle-aged, African American and had a history of heart disease, according to the report.

The study also showed that patients whose heart attacks were linked to sexual activity had higher rates of ventricular fibrillation - a serious cardiac rhythm disturbance - and tachycardia, a higher-than-normal heart rate.

Cardiac arrest results in more than 300,000 deaths each year in the US alone, the researchers say. This happened mostly because only one-third of those who collapsed during received CPR, which could have increased survival chances. Almost 20 percent of people survived in sex-related cases, compared to only about 13 percent survival odds for other patients.

Dr Chugh said: "These findings highlight the importance of continued efforts to educate the public on the importance of bystander CPR for sudden cardiac arrest, irrespective of the circumstance". As the same situation is visualized in a number of dramatic series where an older man can get a heart attack during sex.
