摘要
目的 应用心肌灌注分级 (MBG)的方法判断前壁急性心肌梗死患者直接经皮冠状动脉介入治疗 (AMI PCI)后的无再流现象 ,并评价其对局部、整体心室收缩功能和同步性的影响。方法2 0 0 0年 5月~ 2 0 0 2年 12月首发前壁AMI并于 6~ 12小时内行直接PCI的患者 12 8例 ,应用MBG方法将患者分为无再流组 (MBG 0~ 1级 )和有再流组 (MBG 2~ 3级 ) ,其中无再流组 36例 (男 2 2例 ,女 14例 ) ,平均年龄 (6 6 2 3± 13 17)岁 ,有再流组 92例 (男 5 8例 ,女 34例 ) ,平均年龄 (6 3 18±11 73)岁。于PCI后即行左心室造影 ,测定心室容积、压力参数和室壁运动积分 (WMS) ;AMI后 1周时行平衡法核素心室造影 ,测定左室整体和局部收缩功能、舒张功能和收缩同步性参数 ;AMI后 6个月随访时重复行心室造影和核素心室造影检查测定上述参数 ,同时随访并记录术后 6个月内主要不良心脏事件 (MACE)的发生率。结果  (1)AMI PCI后 6个月随访时 ,无再流组左室收缩末容积指数、左心室舒张末期容积指数、WMS和左室舒张末期压均较有再流组明显增高 [(5 0 35± 7 2 4 )ml/m2 比 (39 6 4± 7 15 )ml/m2 ,(86 4 7± 11 77)ml/m2 比 (77 19± 9 2 9)ml/m2 ,(10 11± 1 94 )比(7 92± 1 6 6 ) ,(16 38± 3 2 1)mmHg(1mmHg =0 133kPa)比
