心电图墓碑样ST段抬高与AMI早期左室重构的关系

目的　评价墓碑样ST段抬高对AMI早期左室重构的影响。方法　对 12 5例初发的AMI,按梗死部位分为前壁和下壁组 ,根据ECG的ST段变化再分为墓碑样抬高亚组和非墓碑样抬高 (通常型 )亚组。在起病第四周用超声心动图检查室壁运动情况 ,测量并计算左室收缩末期容积(ESV) ,舒张末期容积 (EDV) ,每搏输出量 (SV)和射血分数(EF) ,并与对照组比较。结果　在前壁梗死墓碑样抬高组EDV =(16 8 19± 11 0 3)mL ,ESV =(116 93± 19 31)mL ,SV =(5 1 2 6± 7 94 )mL ,EF(30 4 7± 12 37) % ,P <0 0 1;通常组EDV =(133 4 3± 5 73)mL ,ESV =(6 6 92± 9 0 7)mL ,SV =(6 6 5 1± 9 7)mL ,EF =(49 84± 13) %。在下壁梗死 ,墓碑样抬高组EDV =(14 3 0 5± 15 4 7)mL ,ESV =(88 12± 14 75 )mL ,SV =(5 4 93± 12 0 9)mL ,EF =(38 39± 10 8) % ,P <0 0 5。通常组EDV =(12 8 78± 12 2 5 )mL ,ESV =(5 7 5 1± 8 0 4 )mL ,SV=(71 2 7± 4 4 7)mL ,EF =(5 5 34± 9 3) %。墓碑样抬高组较通常组更多发生室壁瘤。结论　心电图墓碑样ST段抬高与AMI早期左室重构高度相关
