Abstract: 目的:通过49例心肌梗塞患者PTCA术前及术后2~3个月进行药物介入核素心肌显像,研究改良硝酸甘油法(简称改良硝甘法)介入99mTc-甲氧基异丁基异腈心肌显像对存活心肌的检测.方法:分别对33例改良组及16例普通组的心肌梗塞患者进行了静息-改良硝甘法和静息-普通硝甘法介入心肌显像,并于术后2~3个月重复显像.结果:改良组静息显像异常节段97个,改良硝甘法介入后有62个节段再填充,再填充率63.9%;普通组静息显像异常节段51个,普通硝甘法介入后有24个节段再填充,再填充率47.1%;两组差异有显著意义(P<0.01).经皮血管再通术后复查静息心肌显像,与术前硝甘法显像比较,灌注改善的预测准确率为90.7%和70.6%.结论:改良硝甘法介入可明显提高对存活心肌检测的灵敏度和特异性,且副作用少.
