摘要(Abstract)：
我国目前对经皮腔内冠状动脉成形术(PTCA)术后再狭窄的资料报道较少.本研究对592例PTCA成功的病人(男503例、女89例,平均年龄58.4±9.1岁)进行术后临床及冠状动脉造影随访.记录临床症状的复发,Holter动态心电图监测,次极量心电图运动试验和~(99m)Tc-MIBI动态心肌灌注显像手术后3个月、6个月和半年的结果.其中62例病人平均手术后10.4±7.6个月进行冠状动脉造影随访.并以冠状动脉造影的结果将此62例病人分为再狭窄组(35例)和无再狭窄组(27例),观察心绞痛症状和三种无创性检查对再狭窄预测的特异性和敏感性.结果表明:心绞痛症状、Holter动态心电图、次极量心电图运动试验和~99mTc-MIBI心肌灌注显像对再狭窄诊断的特异性和敏感性分别为75.7%和72.0%;71.4%和86.7%;66.7%和73.1%;76.5%和83.3%.如果结合临床症状和三种无创性检查组成综合缺血指标,对PTCA术后再狭窄诊断的特异性和敏感性可进一步提高,分别为85.2%和92.9%.本文对PTCA术后临床症状,无创性检查和冠状动脉造影的随访可能对今后国内大规模临床随访提供有益的参考.
