Erection is an hemodynamic event and accordingly, erectile dysfunction is closely related with ischemic heart diseases. Sufficient study has yet to be made of this relation.


Fifty-eight patients with erectile dysfunction participated in the present study. Intracavernous injection tests and color Doppler examination were conducted for assessment of erectile function. For patients with history of ischemic heart disease, we referred to their doctor for data from their examinations. For patients otherwise, chest X-rays and electrocardiograms in the resting position were obtained and also electrocardiograms following exercise. Echocardiograms, treadmill test results, thallium exercise scintigrams, and coronary angiograms were obtained as requires for diagnosis.


Eighteen patients (31.0%) were diagnosed as ischemic heart disease or at high risk. Although 6 of them had been already diagnosed with ischemic heart disease, 12 were newly diagnosed by the exercise tests. Among these 18 patients 16 had one or more significant risk factors for ischemic heart disease such as age, hyperlipidemia, and diabetes mellitus. 3.7% of patients whose peak systolic velocity in the cavernous artery was equal to or exceeded 35 cm/sec had ischemic heart disease or were at high risk. 54.8% of patients with peak systolic velocity of less than 35 cm/sec had ischemic heart disease or were at high risk.


In erectile dysfunctional patients, incidence of complications with symptomatic or asymptomatic ischemic heart disease was found to be high. Therefore, in patients with risk factors or low peak systolic velocity in the cavernous artery, exercise tests should be implemented prior to treatment of erectile dysfunction.
