Abstract: Objective To study the risk factors of patients with atherosclerotic renal artery stenosis (ARAS) and the relation with renal function.Methods The renal function of 64 ARAS patients was measured and compared with 36 healthy controls.Results Compared with the healthy controls, the incidence rates of morbilities of coronary artery disease, more than single-vessel, peripheral vascular disease, renal inadequacy increased significantly ( P<0.05), and the age, pulse pressure, levels of blood urea nitrogen (BUN), serum creatinine (SCr) were significantly higher ( P<0.01) in ARAS patients.Conclusion The elder, coronary artery disease, more than single-vessel, large pulse pressure, peripheral vascular disease and renal inadequacy are risk factors for ARAS. Severe renal artery stenosis may lead to renal inadequacy.
