Abstract
OBJECTIVES: To prospectively define the potential predictors of asymptomatic ischemic heart disease in patients with vasculogenic erectile dysfunction using a simple and practical method. Most patients with vasculogenic erectile dysfunction are known to have at least one significant cardiovascular risk factor. METHODS: After baseline evaluations, patients with erectile dysfunction of presumed vascular origin, who were older than 45 years and with no history of ischemic heart disease, were enrolled in the study. According to the results of repeated pharmacologic erection tests, we divided patients into responders and nonresponders. The cardiologic evaluations consisted of a comprehensive history taking, the assessment of cardiovascular risk factors, a physical examination, and an exercise treadmill test. RESULTS: A total of 97 patients completed the study. Fifteen (32.6%) of 46 responders and 25 (49.0%) of 51 nonresponders, respectively, had two or more cardiovascular risk factors (P = 0.101). Ischemic ST-segment changes on the exercise treadmill test were only observed in 8 nonresponders (15.7%) (P = 0.006). All these patients were older than 55 years, and seven had two or more cardiovascular risk factors, including hypertension. CONCLUSIONS: On the basis of these preliminary data, we suggest that cardiovascular evaluations may prove beneficial before prescribing sildenafil to patients with vasculogenic erectile dysfunction who are nonresponders to the pharmacologic erection test, are older than 55 years, and have two or more risk factors, including hypertension.
