目的 :探讨冠脉介入术对心肌梗死心功能不全患者的疗效。方法 :左室射血分数 (L VEF) <5 0 %的心肌梗死患者 30例 ,分别于冠脉介入术前及术后 3个月检查 2维超声心动图 (2 DE) ,观察患者室壁节段运动指数 (WMSI)和 L VEF的变化。结果 :2例患者死亡 ,2 0例术后 WMSI和 L VEF较术前明显改善 (定为心功能改善组 ) ,8例无明显变化 (定为心功能无改善组 ) ;心功能改善组中急性心肌梗死较陈旧性心肌梗死患者 WMSI改善明显。结论 :有大量存活心肌的心肌梗死心功能不全患者 ,冠脉介入术能使患者获益 ;心梗患者尽早行冠脉介入术能使患者心功能及早恢复。
Objective: To investigate the efficacy of coronary intervention in patients with myocardial infarction with heart failure. Methods: Thirty patients with myocardial infarction with LVEF <50% were examined 2-dimensional echocardiography (2 DE) before and 3 months after coronary intervention respectively. Segmental motor index (WMSI) and L VEF changes. Results: Two patients died. Twenty patients had significant improvement in WMSI and L VEF after operation (defined as cardiac function improvement group), no significant changes in 8 patients (no improvement in cardiac function) Acute myocardial infarction improved significantly than WMSI in patients with old myocardial infarction. Conclusion: Patients with cardiac insufficiency with myocardial infarction who have a large number of surviving myocardium can benefit from coronary intervention. As soon as possible, patients with myocardial infarction can recover their heart function as soon as possible after coronary intervention.
