The impact of sexual activity on the cardiovascular system
Posted by Alex
Among the first authors to report on the cardiovascular response during intercourse were Littler et al. in 1974. He reported a significant rise in blood pressure during sexual arousal due to sympathetic activity and peripheral vasoconstriction (systolic increased by up to 100 mmHg, diastolic by up to 48 mmHg) and a significant increase in heart rate (up to 87 beats/min). After orgasm is reached, lower values of blood pressure and heart rate are attained than before intercourse. Bohlen and co-workers published on cardiovascular strain during four sexual activities. Buy Viagra Soft Tabs Non-intercourse sexual activities gave rise to the least amount of cardiovascular strain, whereas intercourse (man-on-top) with a new partner gave rise to maximal cardiovascular strain. Measurement of exhaled gases during sexual activity with the usual partner has demonstrated relatively low workloads ranging from two to six metabolic equivalent tasks (METs) depending on the position during intercourse. The cardiac workload during intercourse has been equated to completing stage I on the Bruce protocol, or a workload of four to six METs, in relation to the physiological responses to sexual activity, including a rise in systolic blood pressure to up to 180 mmHg and an increase in heart rate to up to 130 beats/min. It is important to realise that cardiac workload varies between individuals and with different sexual activities, taking into account the additional cardiac workload related to emotional stress. Buy Viagra Professional The patient’s description of his functional capacity may be helpful in assessing whether sexual activity is likely to provoke clinically important cardiac symptoms. The cardiac workloads for sexual activity are generally analogous to ironing (2-4 METs), walking a mile in 20 minutes (3-4 METs), or playing golf (3-5 METs). canada pharmacy
Once men who have coronary artery disease and ED are allowed to engage in sexual activities, the risk of sexual activity precipitating a cardiac event becomes a potential concern. Among men who have suffered myo¬cardial infarction, approximately 25% report cessation of sexual activities and 50% report decreased sexual activity. Patients with angina pectoris show less dramatic statistics. Following coronary artery bypass grafting, 36% of patients report less frequent sexual activity and nearly 10% report an increased frequency. Although many men and their partners are concerned about resuming sexual activity following myocardial infarction, recent data do not endorse this overrated concern. In patients without a cardiac history the baseline risk of acute myocardial infarction in the first two hours after sexual intercourse is increased by 2.5. Viagra Super Active For patients with a history of myocardial infarction the baseline risk was increased by 2.9. It seems that the relative cardiovascular risk for sexual activities in patients with a previous myocardial infarction is slightly higher than in healthy subjects. In addition, it is suggested that regular exercise reduces or eUminates the risk of myocardial infarction during or immediately after sexual activity. It is important that patients who develop significant anginal symptoms or ischaemia during exertion or exercise testing and patients with unstable angina or advanced heart failure should undergo cardiac evaluation and treatment before resuming sexual activity. canadian pharmacy online
