摘要 目的探讨心肌声学造影对急性心肌梗死(AMI)患者经皮冠脉介入术(PCI)后TIMI血流达Ⅲ级者心肌微循环的影响。方法采用Sequoia512型超声心动仪,应用二次谐波成像和高机械指数超声发射,对30例AMI患者PCI术后进行经静脉声诺维心肌声学造影显像和超声检查。结果共210个节段与梗死相关动脉再灌注有关,灌注正常即心肌造影计分(MCS)1分146段,灌注不良MCS 0.5分53段,无灌注MCS 0分11段。运动正常节段中MCS 1分者明显高于运动异常节段(P<0.05)。根据声学造影记分指数(CSI)将患者分为A组22例(CSI>0.8),B组8例(CSI≤0.8)。A组射血分数(EF)显著大于B组(P<0.05)。结论TIMIⅢ级血流并非再灌注成功的金标准。心肌微循环与心室收缩功能有一定相关性,微循环良好的患者EF值大于微循环较差者。经静脉声诺维心肌声学造影是一种安全无创的检测手段,是反映心肌微循环灌注的有效方法。
