Sex increases risk of heart attack for those who are unfit
Sudden bursts of moderate to intense physical activity -- such as jogging or having sex -- significantly increase the risk of having a heart attack, especially in people who do not get regular exercise, US researchers said yesterday.
The study, by Dr Issa Dahabreh of Tufts Medical Center in Boston and her team, appears in JAMA, the 'Journal of the American Medical Association'.
The team found that people were 3.5 times more likely to get a heart attack or have sudden cardiac death when exercising, compared to when they are not.
And they are 2.7 times more likely to get a heart attack when they are having sex or immediately afterwards, compared with when they are not.
However, Jessica Paulus, another Tufts researcher who worked on the study, said: "What we don't want to do is for the public to think exercise is bad."
She added that people who do not exercise regularly needed to start any exercise programme slowly, gradually increasing the intensity of the workout over time.
