【摘要】 目的:探讨冠心病患者动脉硬化性肾动脉狭窄的发病情况及其危险因素。方法:对62例临床诊断或怀疑冠心病的患者在冠状动脉造影和心室造影后行常规肾动脉造影,同时调查动脉粥样硬化的常见危险因素及血肌酐水平与肾动脉狭窄(RAS)的关系。结果:经冠状动脉造影证实的46例冠心病患者中,RAS的发生率为34.8％,显著高于冠状动脉造影完全正常者的6.3％(5/16),P<O.05。冠脉多支病变组中的RAS发生率明显高于单支病变组(x~2=4.51,P<0.05)。RAS也多见于高龄(t=2.09 P<3.05),有高血压病史(x~2=5.68,P<0.05)及肾功能不全的患者(x~2=5.68,P<0.05)。结论:冠心病的危险因素与肾动脉狭窄存在相关性。冠心病、高血压及肾功能不全预示有肾动脉狭窄的可能。更多还原

【Abstract】 Objective: This study is to evaluate the correlation between coronary artery disease (CAD) and renal artery stenosis (RAS) and to identify the risk factors of RAS. Methods :Sixty-two patients with CAD or suspected CAD were carried out renal artery angiography after coronary angiography. Simultaneous risk factors of atherosclerotic disease, blood creatine level were surveyed. Results: Renal artery narrowing was identified in 17 of the 62 (27. 4%) patients and 16 of the 46 (34. 8%) patients with CAD determined by angiography. while 1 of the 16 (6. 3%) patients whose coronary artery was normal according coronary angiography. Patients in RAS group were older and had higher occurrence of renal dysfunction, hypertension, and CAD (especially multi-vessel disease) (P<0. 05). Conclusion: There is correlation between CAD and renal artery stenosis . Age. hypertension and renal dysfunction are risk factor of renal stenosis.更多还原
