One of the major areas of concern is the amount of physical strain during sexual intercourse. Experts say that sex does not put much physical strain on the heart. According to a study, where a Holter monitor was used to record the ECG of couples during sexual intercourse, the act has only a moderate affect. “Rises in heart rate also occur for a brief period during stair climbing and brisk walking,” said the study.

Though sex after recovery is not risky for heart patients, Dr Jain suggests some practical tips to regain a normal sex life:
Time to resume sexual intercourse: This depends on factors like general health and physical stamina prior to illness, strength of heart muscle contractions, frequency and severity of angina, ability to resume normal physical activity and wound healing. It is best to resume when one can climb two flights of stairs without breathlessness, say four to six weeks following an uncomplicated stroke, and a little later after surgery.
Getting started: Cuddling without worrying about performance is desirable. Touching and caressing without penetrative sex and orgasm needs less energy.
Don’t skip the foreplay: Foreplay allows a gradual rise in heart rate. Room temperature should be comfortable as extreme temperatures are stressful for heart.
Desirable positions: After heart surgery, it’s best to take positions that impose least strain on the chest wound and permit free breathing. Supporting the body on hands, when on top should be avoided. This position involves a lot of isometric exercises, which may be strenuous. Partial support on the elbows and forearms is better.
