Objective To explore the correlation between the coronary and iliac artery atherosclerosis by simultaneously conducting iliac angiography and coronary angiography (CAG). Methods A total of 288 patients who underwent iliac angiography immediately after coronary angiography were enrolled. The detection rate and risk factors of iliac atherosclerosis and their correlation with coronary atherosclerosis and its severity were analyzed. Results The mean age of the patients was (66.64±10.58) years. The total detection rate of iliac atherosclerosis was 42.7% (123/288). The incidence of iliac atherosclerosis of patients with coronary atherosclerosis was 54.8%, which was significantly higher than that (23.4%) of patients without coronary atherosclerosis (P=0.000). The result of risk factor analysis showed that elder, male, smoking, hypertension, diabetes mellitus, and hypercholesterolemia were risk factors of iliac atherosclerosis. The iliac atherosclerosis significant correlated with coronary atherosclerosis and its severity (the number of involved vessels) (P=0.001 and 0.000). Conclusion Risk factors of iliac atherosclerosis are similar to those of coronary atherosclerosis and iliac atherosclerosis also correlates with the severity of coronary atherosclerosis.
