- It's Complicated
A study by the American Heart Association found that men who suffer fatal heart attacks during sex are more likely to be having an affair at the time. Published in the journal Circulation, the study reviewed 6,000 autopsy reports of people who suffered fatal cardiac events. Less than 1% of these people died during sex. However, of this number, 9 out of 10 were men, and 75% of these men were having an affair.
