摘要(Abstract)：

目的评价冠状动脉慢性完全闭塞病变(chronic total occlusion,CTO)侧支循环的形成情况,对影响侧支循环建立的因素进行探讨。方法连续搜集2004年1月至2008年12月上海市中山医院1485例冠状动脉造影提示完全闭塞病变并确认为CTO(闭塞时间>3个月)病变者638例,根据冠状动脉造影结果采用Rentrop法评价侧支循环的开放情况,将侧支循环积分2、3级判断为侧支循环良好,侧支循环积分0、1级判断为侧支循环不良;对两组患者在临床影响因素、病变影像特征、介入治疗资料等进行分析。结果两组患者年龄(63.6±10.7)岁比(66.5±11.2)岁,t=3.638,P<0.05;合并既往明确心肌梗死史(32.8%比39.5%,χ2=2.043,P<0.05);中重度吸烟史44.1%比59.5%,χ2=15.277,P<0.01;高尿酸水平(355.79±92.69)mmol/L比(370.94±94.81)mmol/L,t=2.697,P<0.05及空腹血糖水平升高(5.51±1.38)mmol/L比(6.67±1.41)mmol/L,t=2.299,P<0.05;开口闭塞病变29.8%比20.7%,χ2=6.927,P<0.01及病变近端中重度迂曲者19.1%比26.2%,χ2=4.551,P<0.05,多出现侧支循环不良;经多元回归分析,既往有中重度吸烟史(OR:0.191,P<0.05,95%CI:0.052～0.699)、空腹血糖水平升高(OR:0.377,P<0.05,95%CI:0.092～0.989)为CTO病变侧支循环形成不良的独立预测因素;而闭塞血管及位置、心绞痛病程、既往心梗史等方面差异无统计学意义。结论本研究显示中重度吸烟史、空腹血糖水平升高对于CTO病变侧支循环形成具有独立的负向预测作用,而心绞痛病程、心肌梗死等因素对其无明确影响作用。
