Abstract:

目的应用超声心动图量化评价经皮冠状动脉介入(PCI)术后ST段抬高急性冠脉综合征(STEACS)患者左心室结构和收缩功能损害的恢复程度。方法选择经冠状动脉造影(CAG)证实存在冠状动脉狭窄或闭塞并接受PCI术的STEACS患者20例,比较术后与术前超声心动图指标及超声征象的变化,指标包括室间隔(IVS)与左室后壁(LVPW)厚度、左心室舒张末期内径(LVDd)和收缩末期内径(LVDs)、左室射血分值(LVEF)和左室短轴缩短率(FS)、左室舒张末期容量(LVVd)和收缩末期容量(LVVs);超声征象包括左室室壁瘤和附壁血栓等。结果(1)20例患者PCI术后与术前超声心动图指标相比LVEF、FS术后明显提高(P<0.01);LVVd术后明显增大(P<0.05)。(2)术前梗死区延展4例(20%)、术后室壁瘤形成1例(5%);术前无左室附壁血栓,术后发生1例(5%)。结论PCI术后左室收缩功能明显提高,左室舒末容量增大,超声心动图为评价PCI术后STEACS患者左心室损害恢复程度提供了量化指标。
