Abstract
The puposes of this study were to determine the prevalence of angiographically significant renal artery stenosis in a patient population referred for diagnostic coronary angiography and to know different variables which can predict the presence of significant renal artery stenosis. After left ventriculography, abnormal aortography was performed to screen for the presence of renal artery disease.
A convenience sample of 659 consecutive patients undergoing diagnostic coronary angiography were enrolled in this study. Significant renal artery diseae ( 50% diameter narrowing) was identified in 76 patients (11.5%) and insignificant renal artery disease in 29 patients (4.4%). Thus, patients with normal renal arteries or with insignificant disease were 583 patients (88.5%).In patients with significant renal artery stenosis, unilateral affection was present in (63.7%) and bilateral affection in 36.3% of cases.
We have studied the prevalence of significant renal artery stenosis in different clinical conditions. Our study showed that, the prevalence increases as age of aptients increases (from 0% in 30-39 age group to 24.1% in 70-79 year-age group). The prevalence of RAS in males was 12% versus 9.5% in females. In smokers the prevalence was 11.6% versus 11.4% in non-smokers. In hypertensive patients the prevalence was 13.9% versus 4% in nonhypertensives. In diabetic patients, the prevalence was 16.6% with more prevalence among IDDM patient (22.6%) versus 15.2% in MDDM.
