Aim To evaluate the incidence and risk factors of atherosclerotic renal artery stenosis(ARAS) undergoing coronary angiography.Methods A total of 279 consecutive Chinese patients with coronary artery desease confirmed by coronary angiography underwent an abdominal aortogram in the same sitting to screen for ARAS.Patient demographics and comorbidities were analyzed for any association with ARAS.Results A total of 80(28.7%) patients was found to have significant ARAS,60(34.3%) of the 175 patients with coronary artery desease who had at least one coronary artery of ≥50% diameter stenosis,20 cases had atherosclerotic renal artery stenosis in 104 patients of normal coronary arteriography.The frequency of ARAS increased with the number of stenotic coronary arteries.By multivariate logistic regression analysis,smoking,pulse pressure(PP),coronary artery stenosis,and serum creatinine were independent predictors of ARAS.Conclusion Abdominal DSA should be routinely performed in patients with coronary artery desease undergoing coronary angiography to identify ARAS,especially in those associated with hypertension and coronary artery disease.
