Too Much Sex Unlikely To Cause Heart Failure

Sex rarely causes hearts to stop, research says Fewer than one in five men who suffer cardiac arrest during sex survive — because their partners do not know CPR

Sudden cardiac arrest is, more often than not, fatal, and it requires immediate specialized attention in order for the worst outcome to be prevented.

Sudden cardiac arrest (SCA) is similar to a heart attack, but the terms aren't quite interchangeable because the physiology behind them isn't the same. 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.

But it can't give a more detailed risk analysis on how likely sex is to trigger a heart attack compared with resting or other activity without knowing how frequently these people were having sex.

For a case of cardiac arrest to be considered related to sexual activity, however, it was required to have occurred either "during or within 1 hour of sexual intercourse".

The study hence concludes that 1% of the cardiac arrest happens because of sex in men where the percentage is 0.1% in women.

"I'm a little surprised at the really tiny number", said study senior researcher Dr. Sumeet Chugh, medical director of the Heart Rhythm Center at Cedars-Sinai Medical Center in Los Angeles.

There are a lot of unknown variables that could have affected the data-drug use, frequency of sex-but all things considered sex-induced SCA is rare enough that most people shouldn't worry about it.

"Previously we would say the risk is probably low, but we don't know how low", Chugh noted. But 94% of those victims had a history of heart disease, NBC News reports.

Looking at the numbers, the researchers concluded that the overall risk of cardiac arrest being triggered by sexual activity was low, and even lower for women. During this time 4.5 thousand people died from sudden cardiac arrest, which allowed the experts to determine the relationship of these cases with sex. Just 12% of patients in the study survived.

Only one-third of these SCA cases received bystander CPR.

"These findings highlight the importance of continued efforts to educate the public on the importance of bystander CPR for SCA, irrespective of the circumstance", Chugh said in a press release.
