目的探讨急性心肌梗死(AMI)后ST段持续抬高的预后意义。方法选择2006年7月～2008年6月92例首次急性ST段抬高性前壁心肌梗死的连续住院患者作为研究对象。根据静息心电图Q波导联是否存在ST段抬高,将患者分为ST段抬高组(52例)和非ST段抬高组(40例)。结果ST段抬高组入院后CKMB水平(140±21U/L)明显高于非ST段抬高组(90±15U/L),其他一般临床资料两组之间差异无统计学意义;出院时两组心脏超声资料显示,ST段抬高组心功能较差,平均经过2年随访,复查心脏超声,两组心脏功能均有不同程度改善,但ST段抬高组心脏功能仍较非ST段抬高组差。结论AMI后ST段持续性抬高,与较大面积的梗死、较差的心功能有关,并在随访2年中更易发生心室重构。
Objective To investigate the prognostic significance of ST segment elevation after acute myocardial infarction (AMI). Methods From July 2006 to June 2008, 92 consecutive inpatients with first acute ST-elevation anterior myocardial infarction were selected as study subjects. Patients were divided into ST-segment elevation (n = 52) and non-ST-segment elevation (n = 40) patients according to resting Q-wave Q-strands. Results After admission, the level of CKMB in ST segment elevation group (140 ± 21U / L) was significantly higher than that in non-ST segment elevation group (90 ± 15U / L). There was no significant difference in other general clinical data between the two groups Two groups of echocardiographic data showed that the cardiac function of ST segment elevation group was poor. After a mean follow-up of 2 years, the echocardiography was reviewed. The cardiac function of both groups improved to some extent. However, Raise the group difference. CONCLUSIONS: The ST-segment elevation after AMI is associated with a larger area of infarction and poorer cardiac function and is more likely to occur during 2 years of follow-up.
