心电图碎裂QRS波预测ST段抬高型心肌梗死患者1年预后情况观察

摘要

Objective To investigate the results of prognosis year with fragmented QRS wave of ECG in ST-segment elevation myocardial infarction. Methods 150 patients ST segment elevation myocardial infarction were studied, and divided into a study group and a control group. Study Group with 74 cases of STEMI patients with fQRS, in the control group of 76 patients without fQRS of STEMI patients. Aneurysm, wall motion abnormalities, LVEF<50%incidence, LVEF, LVED other indicators; hospitalized during Killip grade 3-4, malignant arrhythmias, sudden cardiac death Happening of the two groups were recorded and compared. Results The study group during hospitalization Killip grade 3-4 and the incidence of malignant arrhythmia was significantly higher than the control group, the difference was statistically significant (P < 0.05); There was no significant difference in the incidence of cardiac death of two groups(P>0.05).During hospitalization, the study group with LVEF <50% was compared with the control group (P < 0.05); aneurysm, abnormal wall motion, LVEF, LVED other indicators of the two groups were compared(P >0.05). 1-year follow-up, the study group with aneurysm, the incidence of wall motion abnormalities were better than the control group, the difference was not statistically significant (P>0.05);LVEF of the study group was significantly lower than the control group, while LVEF <50% and LVED incidence of the study group were significantly higher, the difference was statistically significant (P < 0.05). Conclusion Fragmented QRS wave of ECG ST-segment elevation myocardial infarction can better predict the prognosis of patients, it is certain clinical value.%目的：探究心电图碎裂QRS波（fQRS）预测ST段抬高型心肌梗死（STEMI）患者1年预后情况。方法选择ST段抬高型心肌梗死患者150例进行研究，将其分为研究组和对照组。其中研究组为74例fQRS的STEMI患者，对照组为76例无fQRS的STEMI患者。分别记录、比较两组患者的室壁瘤、室壁运动异常、LVEF＜50%发生率、LVEF、LVED等指标以及两组患者住院期间Killip 3~4级、恶性心率失常、心源性死亡的发生情况。结果住院期间，研究组Killip 3~4级以及恶性心率失常的发生率明显高于对照组，两组比较，差异有统计学意义（P＜0.05）；两组心源性死亡的发生率差异无统计学意义（P＞0.05）。住院期间，研究组与对照组相比，LVEF＜50%的发生率较高，差异有统计学意义（P＜0.05）；室壁瘤、室壁运动异常、LVEF、LVED等指标差异无统计学意义（P＞0.05）。随访1年，研究组与对照组室壁瘤、室壁运动异常的发生率相比，差异无统计学意义（P＞0.05）；研究组LVEF明显低于对照组，而研究组LVEF＜50%的发生率及LVED显著高于对照组，两组相比，差异有统计学意义（P＜0.05）。结论心电图碎裂QRS波对于ST段抬高型心肌梗死患者预后的预测效果较好，具有一定的临床应用价值。
