摘要 目的采用二维斑点追踪技术(2D-STI)检测冠状动脉左前降支供血区心肌纵向应变,探讨其评估缺血心肌局部收缩功能的价值。方法使用2D-STI检测不同狭窄程度(〈50%、50%~75%、〉75%)及未见明确狭窄的左前降支供血区心肌纵向应变参数:心内膜下、心外膜下及区域心肌收缩期纵向应变峰值-LS-endo、LS-epi、LS-Territorial,计算收缩期心肌跨壁纵向应变(LS-mural)。观察PCI术后供血区心肌纵向应变的变化。结果各组内LS-endo均高于对应的LS-epi(均P〈0.01)。随着左前降支狭窄程度增加,LS-endo、LS-epi、LS-Territorial、LS-mural逐渐减低(均P〈0.01)。术后LS-endo、LS-epi、LS-Territorial逐渐增高,LS-mural先增高后缓慢减低再增高。结论2D-STI可定量检测不同层次的心肌纵向应变,反映心肌局部收缩功能,为早期识别缺血心肌、评价PCI术后疗效提供参考依据。
