中文摘要:

目的评价心血管事件高危人群通过测量踝臂指数(ABI)诊断的下肢动脉疾病(PAD)和肾功能的相关性.方法人选5270例年龄≥50岁的心脑血管疾病或存在多重动脉粥样硬化危险因素患者,测定ABI值,采用Cockcrofl-Gault公式计算肌酐清除率(CRCL),观察该人群中ABI异常(ABI≤0.9)和肾功能不全(CRCL＜60ml·min^-1·1.73m^-1)的发生情况及其二者关联.结果 5270例患者中有2648例(50.2%)存在肾功能不全,746例(14.2%)经ABI证实为PAD.ABI与CRCL呈正相关(r=0.217,P<0.001).肾功能不全患者中PAD的患病率显著高于肾功能正常者(19.9%vs.8 3%,P<0.001).经对危险因素和伴随疾病校正后,CRCL与PAD独立相关(OR=0.98,95%CI:0.98～0.99.P<0.001).结论心血管病高危人群中,存在肾功能不全的患者PAD发生率高.

英文摘要:

Objective This study was to examine the relation of peripheral arterial disease (PAD) and renal insufficiency in cardiovascular patients with high risk. Methods PAD, defined as an ankle brachial index (ABI)≤0.9 in either leg and renal insufficiency, defined as an estimated creatinine clearance (CRCL) <60 ml · min^-1 · 1.73 m^-1 were evaluated in 5270 Chinese patients at high risk of CV. Results 2648(50.2%) patients had an estimated ABI≤0.9. ABI and CRCL were positively correlated (r=0.217,P<0.001). The prevalence of PAD in patients with renal dysfunction was significantly higher than those with normal renal function (19.9% vs. 8.3%,P<0.001). The association of ABI≤ 0.9 with CRCL was independent from potential confounders such as age, diabetes, hypertension, hypercholesterolemia, smoking, coronary artery disease and stroke history (OR=0.98, 95%CI: 0.98-0.99, P<0.001). Conclusion Results from the present study demonstrateda remarkably high prevalence of PAD (defined as an ABI≤0.9) among patients with renal dysfunction and at high risk. Even after adjustmentfor important confounders such as age, diabetes, and coronary artery and cerebro-vascular diseases etc., persons with lower CRCL were still more likely to have an ABI≤0.9.
