Comparison of trimetazidine plus sildenafil to chronic nitrates in the control of myocardial ischemia during sexual activity in patients with coronary artery disease

A large proportion of patients who have erectile dysfunction also have coronary artery disease (CAD). In these patients, nitrate therapy is a contraindication to the use of sildenafil. To assess whether the metabolic anti-ischemic agent, trimetazidine, is effective in controlling episodes of myocardial ischemia during sexual activity in patients who have CAD and use long-term nitrate therapy, we studied 38 men (57 ± 6 years of age) who had proved CAD. Patients underwent 24-hour ambulatory electrocardiographic monitoring at baseline, after 1 week of oral nitrate therapy (20 mg 3 times a day), and after 1 week of trimetazidine (20 mg 3 times a day). Patients were asked to engage in
