Abstract： 目的 探讨心电图运动试验测定多项指标联合常规ST段标准诊断冠心病介入术后再狭窄的敏感性和特异性.方法 对2001年11月至2003年12月成功行冠状动脉介入治疗(PCI)的129例患者,在术后3～6个月进行随访,测量心电图运动试验ST/HR指数、QT离散度(QTd)及常规ST段阳性标准三者联合诊断再狭窄,通过冠状动脉造影确定有无再狭窄,评价其诊断再狭窄的价值.结果 三者联合应用诊断再狭窄的敏感性和特异性分别为90.5%、80.2%,高于传统ST段标准诊断的特异性和敏感性(53.3%、66.7%,P＜0.05).结论 QTd联合应用ST/HR指数及常规ST段标准可作为诊断再狭窄的无创手段.
