A study at the University of Florence says that "sudden coital death" is more likely to occur in older married men who, instead of routine sex with their spouses in familiar environment, cheat on their wives with younger women in unfamiliar surroundings.
The Telegraph reports that according to researcher Dr. Alessandra Fisher, “Several interpersonal, sexual, and biological factors are associated with having extramarital affairs. Unfaithfulness in men seems to be associated with a higher risk of major cardiovascular events.”
While researchers are uncertain why this is so, several reasons have been suggested, including stress associated with feelings of guilt, stress associated with keeping the affair secret and the greater sexual demands of a younger woman. MSN suggests that a contributory factor may be that men are more likely to be full of alcohol and rich food at the time they are having sex outside home than when they spend the evening at home with the "old ball-and-chain."
The researchers emphasized however that guilty conscience is a contributory factor.
But regardless of the reasons, The Telegraph reports that the Italian researchers, who reviewed the literature on the effects of infidelity, say there is a strong correlation between unfaithfulness and major cardiovascular events among men.
According to The Huffington Post, the researchers, using key terms such as "unfaithfulness" and "extramarital affairs," analyzed the frequency of heart attacks in men. The Telegraph reports they found that both fatal and non-fatal heart attacks were relatively rare when men stayed at home to have sex with their wives rather than with a young lover outside home.
Daily Mail reports Fisher said: “Extra-martial sex may be hazardous and stressful because the lover is often younger than the primary partner and probably sex occurs more often following excessive drinking and/or eating. It is possible that a secret sexual encounter in an unfamiliar setting may significantly increase blood pressure and heart rate, leading to increased oxygen demand.”
According to The Huffington Post, it is not the first time infidelity has been linked to cardiovascular accident. Forbes reported that "Heart 411: The Only Guide to Heart Health You’ll Ever Need," written by cardiologists Marc Gillinov and Steven Nissen, said, "When heart attacks occur during or after sex, they almost always involve older men in extramarital affairs with young women. For those men, it would have been safer to stay at home and burn off excess energy on a treadmill in the basement."
According to The Huffington Post, in January 2012, the Center for Disease Control and Prevention analyzed autopsy reports of 5,559 people who died suddenly from heart complications and found that 75 percent of those who died during sex were engaging in premarital sex.
A 2009 study found also that men involved in long term extramarital relationships were more likely to go through a major heart event than other men.
The Telegraph reports that the study was published in the Journal of Sexual Medicine
