Good news from a study just published in Circulation:

Sex is the cause of less than 1% of all acute heart attacks, the review said. And autopsy studies suggest that only between 0.6% and 1.7% of sudden deaths are related to sexual activity.

(A word to the wise for cheaters, though: Of those who did die during the act, most were men having “extramarital sexual activity, in most cases with a younger partner in an unfamiliar setting and/or after excessive food and alcohol consumption.”)
