摘要(Abstract)：

目的探讨体重指数(BMI)对择期经皮冠状动脉介入治疗(PCI)术后全因死亡率的影响。方法入选2009年7月至2011年9月接受择期PCI的患者2964例,将患者分为体重正常组(BMI<24.0 kg/m~2,810例)、超重组(24.0≤BMI<28.0 kg/m~2,1454例)、肥胖组(BMI≥28 kg/m~2,700例)。比较各组患者临床特点及术后全因死亡率的差异。结果体重正常组患者年龄大于超重组[(60.1±10.2)岁比(59.2±10.3)岁]和肥胖组[(60.1±10.2)岁比(57.2±11.4)岁],超重组患者年龄大于肥胖组[(59.2±10.3)岁比(57.2±11.4)岁],差异均有统计学意义(均P<0.017);体重正常组患者女性比例高于超重组(30.1%比21.9%),而肥胖组患者女性比例高于超重组(27.9%比21.9%),差异均有统计学意义(均P<0.017)。体重正常组患者高血压病、白细胞计数、血红蛋白、三酰甘油、空腹血糖、前降支近端病变比例等小于超重组和肥胖组,差异均有统计学意义(均P<0.017);肥胖组患者高血压病比例、收缩压、总胆固醇、低密度脂蛋白胆固醇、三酰甘油均高于超重组患者,而估算的肾小球滤过率水平、双联抗血小板治疗比例均低于超重组,差异均有统计学意义(均P<0.017)。平均随访时间为(571.5±130.8)d,失访237例(8.0%),完成随访2727例(92.0%)。体重正常组患者死亡23例(2.8%),超重组死亡23例(1.6%),肥胖组死亡8例(1.1%),三组间比较差异有统计学意义(P=0.027)。单因素分析显示,年龄、BMI、糖尿病、左心室射血分数、血红蛋白、估算的肾小球滤过率、空腹血糖、冠状动脉多支血管病变、PCI处理血管支数、完全血管血运重建是死亡的危险因素(均P<0.05)。将单因素分析P<0.2的变量纳入Cox回归多因素分析显示,与肥胖组患者比较,体重正常组患者术后死亡风险增高(HR 2.241,95%CI 1.154～4.350,P=0.017),超重组患者术后死亡风险差异无统计学意义(HR 1.908,95%CI 0.689～5.291,P=0.213)。结论在接受择期PCI的患者中,超重和肥胖患者预后好于体重正常患者。
