摘要
目的:在诊断或疑诊冠心病的动脉造影患者中观察动脉粥样硬化性肾动脉狭窄(atherosclerotic renal artery stenosis,ARAS)的发生率,了解肾动脉狭窄的发生程度和病变部位的分布情况,寻找及早识别ARAS发生的高危因素。
方法:在2002年10月至2003年11月诊断或疑诊冠心病的住院患者中同时行冠状动脉、肾动脉造影。行动脉造影前采集患者病史和血标本。采用Seldinger技术、Judkins法行冠状动脉、肾动脉造影。以高血压、吸烟、糖尿病、性别、年龄、心衰、周围血管病变、高血脂、肾功能不全为自变量,肾动脉狭窄(renal artery stenosis,RAS)为因变量行单变量Logistic回归分析,再以分析结果有统计学意义的变量为自变量,行多变量Logistic回归分析。P<0.05及以上为相差显著。
结果:13个月收集了126例临床资料,患者平均年龄63.18±9.53岁,其中男82人(65.1%),女44人(34.9%)。共24人有肾动脉病变,占总数的19.04%,13人有明显肾动脉狭窄,占10.32%;单侧肾动脉20例占15.87%,双侧狭窄4例占3.17%;其中肾动脉开口处狭窄为60.7%

Objective: Prevalence of atherosclerotic renal artery stenosis (ARAS) were studied in Patients with coronary artery disease or suspected coronary by angiography, then the degree and location of renal artery stenosis(RAS) were screened, and risk factors of ARAS were identify as early.
Methods: 129 patients were studied from October 2002 and Novenber 2003. Patients' data and blood samples were collected before cardiac catherization and renal artery angioplasty were performed. Coronary artery angiography and renal arteriography performed by Seldinger and Judkins technique. Independent variables included hypertesion, smoking ,
congestive heart failure , diabetes mellitus, age, peripheral vascular disease, serum creatinine, blood cholesterin and glycerin, and dependent variable was RAS. The significant variables in the univariate model were then analyzed in multivariate logistic regression model to identify the best set of independent predictors of RAS.Statistical significance was defined as P<0.05.
Results: 126 patients' mean age were 63.18 +9.53(82 males,44 females).24(19.04%) had ARAS, 13(10.32%) had significant RAS (,50%), Significant unilateral stenosis was 15.87% and bilateral stenosis was 3.17% of the total patients.The ostial lesions was 60.7% ,the main stem was 35.7% and the branch was 3.57% of 28 renal artery stenosis.By univariate and multivariate logistic regression analysis, predictors included smoking(OR=1.26,P=0.044), coronary artery disease(OR=1.91,P=0.003), hyperlipidemia (OR=1.96,P=0.001), triple coronary artery diseases (OR=1.13,P=0.048).
Conclusion: (1) The prevalence of atherosclerotic renal artery stenosis is 19.04% in a patient population undergoing cardiac catheterization, RAS is more commom in the ostial sites. (2) Risk factors of ARAS existencing are smoking , coronary artery disease , peripheral vascular disease , hyperlipidemia , renal insufficience, and independent predictors are smoking , coronary artery disease and hyperlipidemia.(3) There is
significant correlation between triple vessel diseases of CAD and the presence of ARAS.
