Sexual Activity and Heart Attack: Not to Worry

Patients and their partners who avoid sexual activity for fear of
triggering a recurrent heart attack may needlessly deprive themselves
of a rich source of pleasure and satisfaction that contributes greatly
to their quality of life.


In a recent study of over 1200 men and 500 women subjects were
confidentially interviewed about their sexual activity in the hours,
days, and year preceding their heart attack. The fndings: a little bad
news, but mostly good news.

The Bad News


Only half of the patients (age 20-92) reported having any
sexual activity in the year preceding their heart attack. (This raises
an interesting question as to whether lack of any sexual activity
itself increases the risk of heart attack.)


Among those who were sexually active, the act of intercourse about
doubles the risk of heart attack in the subsequent 2-hour period. But
not to worry . . .

The Good News


The absolute increase in risk of heart attack following sexual
activity is so slight that even doubling it is not much of a danger.
For example, the risk of having a heart attack in the two hours
following intercourse might rise from one chance in a million per hour
to two chances in a million per hour÷probably not something to lose
sleep or sex over.

There’s more good news. For those who exercise regularly, there is no increased risk of heart attack following sexual intercourse. Habitual physical exertion two to three times per week protects against all heart disease and effectively eliminates any excess risk associated with sexual activity. In other words, if youâre physically fit, you can put your heart into sexual activity without taxing it!

These findings should be reassuring to the half a million people in the US each year who survive a heart attack and over 11 million patients who have existing heart disease. Patients, partners, and physicians can now reassure themselves that:

sexual activity after heart attack is generally very low risk

regular physical activity promotes a healthy heart and safer, satisfying sex life

As Stanford cardiologist Robert F. DeBusk put it: “Patients should be interested not only in the years in their lives, but also the liveliness of their years.”
