核素心室显像对前壁、下壁急性心肌梗死左室局部收缩功能的评价
Evaluation of left ventricular regional systolic function on patients with acute inferior and anterior wall myocardial infarction by nuclide ventricular imaging
【摘要】 目的 :评价前壁及下壁急性心肌梗死 (AMI)左室局部收缩功能。方法 :于AMI发病后第三周应用门控平衡法核素心室显像检测两壁左室整体及局部射血分数 (LVEF、rEF) ,轴缩短率 (RS) ,局部轴缩短率 (rRS)。结果 :前壁组LVEF (31 5 3± 10 38% )显著低于下壁组(46 5 2± 8 6 5 % ) ,P <0 0 1;前壁组平均室壁运动积分 (1 86± 0 6分 )亦显著低于下壁组 (2 2 0± 0 6分 ) ,P <0 0 1。结论 :AMI急性期左室局部收缩功能和室壁运动状态均与梗死部位有关。前壁AMI左室收缩功能受损程度较下壁AMI更为显著。
【Abstract】 Aim:To evaluate the left ventricular regional systolic function in patients with acute inferior and anterior myocardial infarction(AMI).Methods:In the third week after AMI attack,we measured the global and regional ejection fractions(LVEF,rEF)as well as the global and regional radial shortening(RS,rRS)by nuclide ventricular imaging.Results:The LVEF of anterior wall group(31 53%±10 38%)was significantly lower than that of inferior wall group(46 52%±8 65%),P<0 01;The average ventricular wall motion score of anterior wall group(1 86±0 6)was also significantly lower than that of inferior wall group(2 20±0 6),P<0 01.Conclusion:The left ventricular regional systolic function and ventricular wall motion state of AMI patients were related to the location of infarction position.The heart function was more severely damaged in anterior wall group than in interior wall group.
