摘要 目的应用三维斑点追踪显像技术(3D-STI)评价急性ST段抬高型心肌梗死(STEMI)经皮冠状动脉介入(PCI)术后左心室收缩功能的变化。方法对41例健康体检者(对照组)和41例STEMI患者(病例组)PCI术后第12个月进行3D-STI分析,测量左室整体纵向应变、径向应变及圆周应变及左室射血分数。结果病例组左室整体纵向应变、径向应变及圆周应变及左室射血分数低于对照组(P<0.01)。结论 STEMI患者的心肌变形能力是下降的,虽然经PCI治疗后可以得到改善,但是左室整体收缩功能即使在术后12个月仍然低于正常人,因此PCI术后1年仍然需要长时间随访观察;3D-STI可以定量评价心肌梗死患者左心室心肌收缩功能的异常。
