目的:探讨急性ST段抬高心肌梗死直接PCI术后早期T波倒置与左心室功能的关系。方法:对急性ST段抬高心肌梗死直接PCI术后78例患者,以24小时抬高的T波是否倒置分组,采用超声心动描记术检测左室射血分数、心肌活动指数,评价早期T波倒置与左室功能的关系。结果:早期T波倒置组左心功能优于T波未倒置组(P<0.01),T波深倒置组左心功能优于浅倒置组(P<0.05)。结论:急性ST段抬高心机梗死早期T波倒置可早期评估左心功能、判断预后。
Objective: To investigate the relationship between early T wave inversion and left ventricular function in patients with acute ST-segment elevation myocardial infarction after direct PCI. Methods: 78 patients with acute ST-segment elevation myocardial infarction (PCI) were enrolled in this study. T-wave elevation was performed in 24 hours. The left ventricular ejection fraction and myocardial activity index were measured by echocardiography. The relationship between inversion and left ventricular function. Results: Left heart function of early T wave inversion group was better than that of T wave non - inversion group (P <0.01). Left heart function of T wave deep inversion group was better than that of shallow inversion group (P <0.05). Conclusion: Early ST-segment inversion of acute ST-segment elevation myocardial infarction can assess left ventricular function early and prognosis.
