目的:探讨心电图在急性ST段抬高型心肌梗死患者诊断及预后中应用价值。方法:选取我院近三年来收治的82例急性心肌梗死(AMI)患者作为研究对象,按照是否发生ST段抬高将82例患者分为实验组和对照组,比较两组心梗部位分布、末峰间隔时间及TIMI分级,随访1周,观察两组发生心律失常、再次心梗及心源性休克的比例。结果:实验组患者发生心梗的部位主要是非透壁性,对照组发生心梗的部位主要为下壁性,两组心梗发生部位有显著差异(P<0.05)。实验组的末峰间隔时间和TIMI分级水平相比对照组更高,组间差异有统计学意义(P<0.05)。实验组患者发生再次心梗、心源性休克及心律失常比例高于对照组,组间差异有统计学意义(P<0.05)。结论:急性ST段抬高型心梗的危险程度高、预后差,心电图相关指标可作为临床诊断和预后判断的重要参考。
Objective: To investigate the value of electrocardiogram in the diagnosis and prognosis of patients with acute ST-segment elevation myocardial infarction. Methods: A total of 82 patients with acute myocardial infarction (AMI) treated in our hospital for the past three years were enrolled in this study. According to whether ST-segment elevation occurred or not, 82 patients were divided into experimental group and control group. The distribution of myocardial infarction, Peak interval time and TIMI grade, followed up for 1 week. The incidence of arrhythmia, re-MI and cardiogenic shock in both groups were observed. Results: The myocardial infarction in the experimental group was mainly non-transmural. The myocardial infarction in the control group was mainly inferior wall. There were significant differences between the two groups (P <0.05). Compared with the control group, the peak interval time and the TIMI grade in the experimental group were significantly higher (P <0.05). The incidence of recurrent MI, cardiogenic shock and arrhythmia in the experimental group was higher than that in the control group. The difference was statistically significant (P <0.05). Conclusion: Acute ST-segment elevation myocardial infarction has a high risk and poor prognosis. ECG-related indicators may serve as an important reference for clinical diagnosis and prognosis.
