According to a research letter published in the Journal of the American College of Cardiology, most heart disease patients can safely resume sexual activity after a heart attack without risk of inciting another one.
For the purposes of this study, researchers looked at 536 heart disease patients between the ages of 30 and 70, evaluating their sexual activity in the year before they experienced a heart attack, and then looking at their frequency of sexual activity and its possible association with subsequent cardiovascular events.
"Based on our data, it seems very unlikely that sexual activity is a relevant trigger of heart attack," said Dietrich Rothenbacher, M.D., M.P.H., lead author of the study and professor and chair of the Institute of Epidemiology and Medical Biometry at Ulm University in Ulm, Germany, in a press release.
