摘要
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 of the left ventricular function and the early T wave inversion in patients with acute ST segment elevate myocardial infarction (STEMI) after direct percutaneous coronary intervention. Methods:78 patients with acute STEMI after direct percutaneous coronary intervention were investigated. According to the shape of T waves in 24 hours , they were divided into the early T wave inverse group and the early T wave uninverse group. The left ventricular ejection fraction (LVEF), myocardial performance index were measured by the Echocariogram. The relationship of early T wave inversion and left ventricular function were estimated. Results:Left ventricular function was better in the early T wave inverse group than that in the early T wave uninverse group (P <0.01) , and which was better in the early T wave deeper-inverse group than that in the early T wave deep shallow-inverse group (P<0.05). Conclusion:The early T wave inversion in patients with STEMI can be used to assess left ventricular function and prognosis.
