Having sex can have an effect on the heart. Because in the process of sexual activity, it will cause sympathetic nerve excitation, resulting in increased heart rate, increased cardiac output and myocardial oxygen consumption, increased blood pressure, but for different groups of people, the impact varies. 1. For those who do not have heart disease: sexual activity has little effect on the heart, but helps to enhance the couple’s relationship and exercise cardiopulmonary function. 2. For people with a history of heart disease, such as hypertension, myocardial ischemia, myocardial infarction, arrhythmia, heart failure, etc., this group of people, if they have sex during an acute attack, may exacerbate the primary disease due to the increase in myocardial oxygen consumption, while in the chronic or stable phase of the disease, they can have sex appropriately to reduce the impact on the heart. If there is any discomfort, please consult the doctor in time. Do not be negligent so as not to delay or aggravate the condition.
