【摘要】：目的探讨急性心肌梗死患者非梗死区室壁运动异常与冠脉病变范围及经皮冠状动脉介入治疗(PCI)疗效的关系。方法急性心肌梗死患者464例,根据冠脉造影结果冠脉单支病变236例(A组)、两支病变228例(B组)。患者分别于PCI前后行超声心动图检查,计算室壁运动异常指数(GWMI)。并进行三组间各指标的比较。结果 PCI前A组非梗死区室壁运动增强率明显高于B组(P0.01)。PCI后A组非梗死区室壁运动增强率与B组比较差异无统计学意义(P0.05)。PCI前两组梗死区GWMI明显升高,但两组间比较差异无统计学意义(P0.05)。A组非梗死区GWMI低于B组(P0.05)。与PCI前比较,PCI后两组梗死区和非梗死区GWMI均明显改善(P均0.01)。结论急性心肌梗死非梗死区室壁运动随着冠脉病变范围的增加而减弱,室壁运动异常改善提示PCI治疗有效。
[Abstract]:Objective to investigate the relationship between ventricular wall motion abnormality and coronary artery lesion and percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods according to the results of coronary angiography in 464 patients with acute myocardial infarction, 236 patients (group A) with coronary artery disease and 228 patients (group B) with two vessel lesions were involved. The patients were examined by echocardiography before and after PCI, and the abnormal wall motion index (GWMI).) was calculated. The indexes of the three groups were compared. Results the enhancement rate of ventricular wall motion in group A before PCI was significantly higher than that in group B (P0.01). PCI). There was no significant difference between group A and group B (P0.05) before). PCI. But there was no significant difference between the two groups (P0.05 GWMI in non-infarct area in). A group was lower than that in B group (P0.05). Compared with those before PCI, GWMI in infarct and non infarct area were significantly improved in both groups after PCI (P0. 01). Conclusion Ventricular wall motion in non-infarct area of acute myocardial infarction decreases with the increase of coronary artery lesion. Abnormal improvement of ventricular wall motion suggests that PCI is effective in the treatment of acute myocardial infarction.
