冠心病患者肾动脉狭窄危险因素临床研究

The Clinical Research of Risk Factors of Atherosclerotic Renal Artery Stenosis in Coronary Heart Disease

目的对冠心病患者动脉粥样硬化性肾动脉狭窄的发病率和危险因素进行探讨。方法247例冠状动脉造影诊断为冠心病的患者同时进行选择性或非选择性肾动脉造影。结果冠心病患者肾动脉狭窄的发生率为20%。多因素Logistic回归分析中,年龄、外周血管疾病和冠心病多支病变为肾动脉狭窄的独立危险因素。结论对冠心病患者,尤其是多支病变、高龄、合并外周血管疾病的冠心病患者应常规行选择性肾动脉造影。

Objective To investigate the incidence and risk factors of concomitant atherosclerotic renal artery stenosis（ARAS） and coronary heart disease（CAD）. Methods In the study period 247 patients with known or suspected CAD underwent combined cardiac catheterization and renal artery angiography. Results Incidence of ARAS was 20% （44/220） in CAD. Logistic regression analysis showed only age, degree of coronery artery stenosis, peripheral atherosclerosis disease were independently predictor of ARAS. Conclusions Renal artery angiography should be performed routinely to indentlfy ARAS, especially in the patients with mutil - vessel lesions, old age and peripheral atherosclerosis disease.
