摘要
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。
AIM: To investigate the efficacy of coronary intervention on myocardial infarction patients with left ventricular dysfuction. METHODS: 30 myocardial infarction patients with left ventricular ejection fraction(LVEF) less than 50% were investigated. Wall motion score index (WMSI) and LVEF were measured by two-dimensional echocardiography (2DE) pre-intervention and 3 mo after the coronary intervention respectively. RESULTS: In the follow-up, two patients died, WMSI and LVEF were significantly improved in 20 patients (defined as improved group) and not improved in 8 patients (defined as not improved group). In the improved group, WMSI improved more significantly in the acute myocardial infarction patients than in old myocardial infarction patients. CONCLUSION: Patients with myocardial dysfunction with more viable myocardium after myocardial infarction can get benefit from coronary intervention. Heart function can be reversed quickly by early coronary intervention.
