摘要(Abstract)：
目的 探讨利用声学密度 (AD)定量技术早期评价急性心肌梗死 (AMI)患者行直接经皮冠状动脉腔内成形术 (PTCA)的手术疗效。方法 将 4 0例AMI患者分为两组 :18例病人行直接PTCA治疗 (A组 ) ,2 2例病人用药物治疗 (B组 ) ,比较两组病人在入院第 7天时常规超声心动图检查和用AD技术检测的结果。结果 两组病人常规超声心动图各项检查结果比较差别无显著性 (P >0 0 5 )。AD定量检测结果 :A组的背向散射积分周期变化幅度 (CVIB) (4 2± 1 3)dB明显高于B组 (2 5± 2 4 )dB(P <0 0 1) ;A组校正的周期变化延迟时间 (N Delay) 1 0 9± 0 0 8明显低于B组 1 31± 0 16 (P <0 0 1) ;两组间背向散射积分 (IBS)差异无显著性 (P >0 0 5 )。结论 AD技术能够早期反映AMI再灌注心肌的组织学特征 ,为早期评价介入治疗效果、预测心功能改善情况、判定心肌活性提供了一种新的技术手段。
