Sexual activity is rarely associated with sudden cardiac arrest, a life-threatening malfunction of the heart's electrical system causing the heart to suddenly stop beating, according to preliminary research presented at the American Heart Association's Scientific Sessions 2017, a premier global exchange of the latest advances in cardiovascular science for researchers and clinicians. "Death follows unless emergency treatment is begun immediately". Most of the incidents - around 94 percent - occurred in men around 60 years old on average, according to the study presented during the American Heart Association's Scientific Sessions meeting California on November 12.
During intimacy died from cardiac arrest 30 people, 15 of them felt unwell after sex. "Now we can tell them the risk is very low".
Of the 34 cases, 32 of the cases were men.
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. Only 34 cases occurred during or within an hour of engaging in sex.
Sex resulting in death after a heart attack is a highly unlikely scenario, scientists have deduced.
Cardiac arrest results in more than 300,000 deaths each year in the USA alone, the researchers say.
The experts claimed that despite the myth that sex might cause a heart attack, especially in older men, this is not the case.
Still, only about 1 percent of men who experience sudden cardiac arrest have it happen during sexual activity, a low number that suggests it is not a great threat.
"Over the years, we've had a fair bit of data on physical activity and how it's related to sudden cardiac arrest, but no one had looked specifically at sexual activity", Dr. Chugh said.
Most of the cases were men with a history of heart disease. The researchers and their teams talk to the patient who gets a heart attack and also from the relatives of some who's closed one gets died due to cardiac arrest.
Almost 20 percent of the sex-related hearts attack patients survived, compared to just 12.9 percent of those whose heart attacks weren't linked to sex.
The doctors behind the new research, published in the Journal of the American College of Cardiology, have stressed the importance of public education on CPR "irrespective of circumstance".
