【摘要】 目的 本文利用超声心动图研究老年急性心肌梗死患者冠脉内支架置入术对近期左室功能的影响及疗效。方法 选择60岁以上急性心肌梗死患者，随机分为支架组24例，对照组(未支架组)28例，应用彩色多普勒超声心动图检测2周及4周的左室大小及各项左室功能指标，并应用左室舒张早期血流传播速度(Flow Propagation Velocity，FPV)新指标，判定左室功能。结果 2周时支架组局部室壁运动异常指数(RWSI)显著低于对照组(P<0.05)外，其他各项指标间均无统计学差异，4周时支架组左室射血分数及FPV显著高于对照组(P<0.01)，左心房内径、左室舒张末期内径和收缩末期内径均小于对照组(P<0.05)，RWSI及左室重量指数显著低于对照组(P<0.05)。结论 老年急性心肌梗死进行支架置入术可以冠脉再通，增加冠脉血流，改善心功能，是安全有效的介入性治疗手段，FPV是较正确评价左室舒张功能的新指标。

    【Abstract】 Objective To investigate the effect of coronary stenting on left ventricular function in old patients with AMI by ultra-sound echocardiography.Methods 52cases over60aged AMI patients were randomly divided into the control group(28cases)and stenting group(24cases).Left ventricular diameter and other index of left ventricular function after2weeks and4weeks were measured by color Doppler echocardiography ......
