冠状动脉溶栓治疗急性心肌梗塞的临床观察

通过对急性心肌梗塞（ＡＭＩ）早期（自胸痛到冠脉溶栓开始＜１２小时）患者１５例（治疗组，其中男性１３例，女性２例，平均年龄５４．１３±５．９４岁，前壁梗塞７例，下壁梗塞７例，高侧壁梗塞１例）行冠状动脉内溶栓治疗（治疗组），并与１６例非溶栓治疗患者（对照组，其中男性１２例，女性４例，平均年龄为６２．１８±６．３５岁，前壁梗塞１１例，下壁梗塞５例）比较。结果：治疗组在发病后两周ＵＣＧ示左房内径为３４．７４±３．６３ｍｍ，左室内径５１．２０±４．９１ｍｍ，左室射血分数（ＥＦ）为０．６３±０．１１，明显优于对照组的左房内径３９．９３±３．２１ｍｍ，左室内径５６．４４±５．４７ｍｍ，ＥＦ０．５２±０．１５；运动试验：治疗组１５例中阳性７例，对照组１６例中阳性１１例；经冠脉成形术后运动试验均阴性。从而说明急性心肌梗塞冠脉再通治疗是防止梗塞后心脏几何形状变形（即心室结构重建），从而保存心脏整体与节段的功能，提高梗塞后远期存活率的重要治疗手段。

Treatment of acute myocardial infarction by intracoronary thrombolysis:clinical observation

Fifteen patients with acute myocardial infarction(AMI) were treated by intracoronary thrombolysis.Sixteen patients with AMI did not receive this treatment Different results were seen between intracoronary thrombolysis therapy and nonintracoronary thrombolysis treatment,After this treatment,the UCG and ECG showed the evidence that early reperfusion therapy could preserve global and regional ventricular function,diminish the infarct size,prevent ventricular remodeling,the patients' tolerance to exercise and decrese the mortality of AMI.
