目的探讨完全血运重建与部分血运重建对心肌梗死(以下简称心梗,MI)合并心功能不全患者左室功能的不同改善程度,以评价对预后的影响。方法选择57例心梗合并心功能不全病例,随机分为完全血运重建蛆及部分血运重建组,分别于术前进行小剂量多巴酚丁胺负荷试验评价存活心肌后进行经皮冠状动脉血运重建术(PCI)治疗,22例进行完全血运重建 PCI 治疗,另35例进行部分血运重建 PCI 治疗,并于术前、术后运用超声心动图(UCG)测定左室功能指标左室射血分数(LVEF)、左室室壁运动记分指数(WMSI)、A/V、左室舒张末内径(LVED)进行对比分析。结果完全血运重建组对左室功能的改善显著优于部分血运重建组,差异有显著性意义(P<0.01或 P<0.05)。结论完全血运重建对心梗合并心功能不全病例的左心室功能的改善具有临床意义,可显著改善左室功能,改善预后。
Objective To investigate the effects of complete revascularization and partial revascularization on left ventricular function in patients with myocardial infarction (MI and MI) with left ventricular dysfunction and to evaluate the effect on prognosis. Methods 57 cases of myocardial infarction with heart failure cases were randomly divided into complete revascularization maggots and partial revascularization group, preoperative low-dose dobutamine stress test to evaluate the survival of the myocardium after percutaneous coronary artery Blood vessel reconstruction (PCI), 22 cases of complete revascularization PCI, the other 35 cases of partial revascularization PCI, and preoperative and postoperative use of echocardiography (UCG) to measure left ventricular function indicators LVEF, WMSI, A / V, left ventricular end-diastolic diameter (LVED) were compared and analyzed. Results The improvement of left ventricular function in complete revascularization group was significantly better than that in partial revascularization group, the difference was significant (P <0.01 or P <0.05). Conclusions Complete revascularization has clinical significance for the improvement of left ventricular function in cases of myocardial infarction complicated with cardiac insufficiency. It can significantly improve left ventricular function and improve prognosis.
