Researchers Stacy Mandras and Mandeep Mehra conducted a meta-analysis of studies of sexual activity in men with coronary artery disease. They found that in middle-aged men both with and without such disease, the increases in heart rate, blood pressure and respiratory rate were well within the safe range.
