Scientists stated: "The majority of cases were men with a previous history of cardiovascular disease".
"People will ask their doctors if sex increases their risk of sudden death, and we've never had the answer before because there never was a study", senior study author Dr. Sumeet Chugh, said a statement from Cedars-Sinai Medical Center. Previous studies have confirmed sex can trigger non-fatal cardiac events like heart attacks, but Chugh and colleagues designed their study to determine whether or not sexual activity is a risk factor for SCA in particular, since the condition accounts for 350,000 deaths in the US each year.
Patients who experienced sudden cardiac arrest linked to sexual activity had higher rates of what's know as ventricular fibrillation - a serious cardiac rhythm disturbance - and tachycardia, or a higher-than-normal heart rate.
In total, the scientists identified 4,557 SCAs in Portland during the 13-year study period.
This was slightly higher than the 27 per cent of non-sex triggered heart attacks, the difference was not statistically significant and those individuals might have died alone. Black men are more at risk than other populations, accounting for 19 percent of sex-related cardiac arrest.
It is not the same as a heart attack, in which blood flow to the heart is blocked.
Hasbro reportedly makes a takeover bid for struggling rival Mattel
CEO Margo Georgiadis, who took the reins in January, has warned the business would miss its revenue forecast for the full year. Representatives for Hasbro and Mattel declined comment on the report, saying they don't respond to speculation.
If you have a heart condition and are afraid that sex could trigger cardiac arrest, there's a reason to relax. 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.
Even though sudden cardiac arrest during sexual activity was witnessed by a partner, CPR was performed in only one-third of the cases.
Your next romp with a paramour may blow your mind, but it's unlikely to stop your heart, according to research presented this weekend at the American Heart Association's Scientific Sessions 2017 in Anaheim, California.
One in 100 cases of cardiac arrest in men was associated with sexual activity, compared with one in 1,000 cases in women.
About 19 percent of the patients in sex-related cardiac arrest cases survived their ordeal, compared with an average survival rate of around 10 percent nationwide, he said.
"This highlights the importance of continued efforts to educate the public on the importance of CPR, no matter the circumstance", Chugh said.
