冠状动脉造影患者中肾动脉狭窄的相关研究

Study of Renal Artery Stenosis in Patients Undergoing Coronary Angiography

目的在进行冠状动脉造影的患者中同时进行肾动脉造影,观察肾动脉狭窄的发生率及相关因素研究。方法200例冠状动脉造影患者全部行选择性双侧肾动脉造影,对临床资料和肾动脉狭窄之间的关系进行单变量分析。结果肾动脉狭窄者27例,占13.5%,其中轻度狭窄者(<50%)13例,占6.5%,明显狭窄者14例,占7.0%。明显肾动脉狭窄单变量分析,年龄、吸烟、高血压、糖尿病、颈动脉斑块形成、严重冠状动脉病变是肾动脉狭窄的影响因素。结论在冠状动脉造影尤其冠心病患者中,肾动脉狭窄发生率高,多见于老年合并高血压、严重冠状动脉病变患者,在冠心病患者行冠状动脉造影的同时应常规进行肾动脉造影,以便及早发现肾动脉狭窄。

Objective To evaluate the prevalence of renal artery stenosis of selective renal angiography in patients undergoing coronary angiography,and to identify relative factors for renal artery stenosis. Methods Selective renal angiography was performed immediately in patients after coronary angiography,by univariate between clinic data and renal atrery stenosis. Results Selective renal angiography was performed immediately in 200 patients after coronary angiography,27 patients（13.5%）of renal artery stenosis,of which 13 patients（6.5%） were insignificant（〈50% diameter narrowing） stenosis and 14 patients （7.0 %） of significant stenosis. By univariate analysis, the association of clinic variables with renal artery stenosis was assessed. Univariable redictors included age, smoking, hypertension, diabetes mellitus, coretid artery plaque, signifieant coronary artery disease Were identified as riskfactors of renal artery stenosis. Conclusion Renal artery stenosis is a frequent finding in patients undergoing coronary angiography,esperially in older people with hypertention, signifieant coronary artery disease. These patients should be routinely performed selective renal artery angiography undergoing coronary angiography to identify renal artery stenosis in early.
