The purpose of this study was to determine the prevalence of renal artery stenosis in patients with suspicion of coronary heart disease and hypertension referred for diagnostic coronary angiography. The study material was consisted of 186 (65 females, 121 males; the mean age was 63 10 years; ranged 30-70 years) patients. Coronary angiography and selective renal angiography were performed at the same session. Coronary heart disease was detected in 28 patients (56 %): single vessel disease in 20 patients (16 %), two-vessel disease in 28 patients (15 %) and multiple vessel disease in 47 patients (25 %). Renal artery stenosis was detected in 16 (9 %) of 186 patients. The mean age, sex distribution, the age of hypertension, ejection fraction, left ventricular end diastolic pressure and the profiles of risk factors were not significantly different in patients with and without renal artery stenosis. The incidence of coronary heart disease was significantly higher,in patients with renal artery stenosis than those of without renal artery stenosis (100 % vs 52 %, respectively, p < 0.001). Renal artery stenosis was detected in 16 of 104 patients (15 %) with coronary heart disease. There was renal artery stenosis in 1 of 29 patients (% 3) with one-vessel disease, 3 of 28 patients (11 %) with two-vessel disease and 12 of 47 patients (26 %) with multiple-vessel disease. The difference was statistically different (x2: 7.361, p=0.0252). We concluded that selective renal angiography performing combined with coronary angiography may be very useful to detect the renal artery stenosis in many patients with coronary heart disease associated with hypertension.
