Aim To evaluate the prevalence of atherosclerotic renal artery stenosis(ARAS) in patients undergoing selective coronary angiography,determine the relationship of ARAS and coronary heart disease(CHD),and to investigate the related factors of ARAS.Methods A total of 410 patients with suspected CHD underwent selective renal artery angiography immediately after coronary angiography.Independent sample test and multivariate logistic regression analysis were used to study the independent risk predictors of ARAS.Results 88(21.4%) patients observed with ARAS were included 7.3% in early,9.7% in mediate and 4.3% in severity.The incidence of ARAS in 285 patients with CHD was 26.3%,and it was higher than in patients without CHD(10.4%,P<0.05).130 renal arteries were narrow more than 30% of lumen diameter,with 61.5% in the ostial,36.9% in the main stem,and 3.8% in the branch of renal artery.The multivariate logistic regression analysis released that the important related factors were female,hypercholesterolemia,lower high density lipoprotein(HDL),early renal disfunction,3-vessel lesions and left main lesion in coronary arteries.Conclusions It is useful to perform selective renal artery angiography following coronary angiography.ARAS is not parallel with CHD.Female,hypercholesterolemia,low HDL,early renal disfunction,CHD with 3-vessel lesions and left main lesion are the independently predicts risks for ARAS.
