摘要
目的:探讨碎裂QRS波(fQRS)对ST段抬高型急性心肌梗死(STEMI)患者短期预后的预测价值。方法:选择我院收治的STEMI患者124例,根据心电图结果分为,无fQRS组(62例)和fQRS组(62例)。对比两组危险因素、超声心动图以及并发症。结果:与无fQRS组比较,fQRS组血清心肌肌钙蛋白I [(30.31±25.10)μg/L比(39.47±24.92)μg/L]水平、三支血管病变率(24.19%比41.94%)显著升高(P均<0.05);术后室壁瘤率(9.68%比24.19%)、室壁运动异常率(67.74%比85.48%)及左室舒张末期内径[(46.62±5.01)mm比(52.86±7.93)mm]均显著增加,左室射血分数[(52.69±10.76)%比(47.35±11.24)%]显著降低(P<0.05或<0.01)。fQRS组住院期间并发症总发生率显著高于无fQRS组(45.16%比14.52%,P=0.001)。结论:出现fQRS的ST段抬高型急性心肌梗死患者术后心功能要显著差于无fQRS患者,fQRS对其预后有重要的预测价值。
Objective:To explore predictive value of fragmented QRS wave(fQRS)for short-term prognosis in patients with ST-segment elevation acute myocardial infarction(STEMI).Methods:A total of 124 STEMI patients treated in our hospital were selected.According to ECG result,they were divided into no fQRS group(n=62)and fQRS group(n=62).Risk factors,ECG and complications were compared between two groups.Results:Compared with no fQRS group,there were significant rise in serum level of cardiac troponin I[(30.31±25.10)μg/L vs.(39.47±24.92)μg/L],percentage of triple-vessel coronary disease(24.19%vs.41.94%),postoperative incidence rate of ventricular aneurysm(9.68%vs.24.19%),abnormal rate of ventricular wall motion(67.74%vs.85.48%)and left ventricular end-diastolic dimension[(46.62±5.01)mm vs.(52.86±7.93)mm],and significant reduction in left ventricular ejection fraction[(52.69±10.76)%vs.(47.35±11.24)%]in fQRS group,P﹤0.05 or﹤0.01.Total complications rate in hospitalization of fQRS group was significant rise than that of fQRS group(45.16%比14.52%,P=0.001).Conclusion:Postoperative cardiac function of STEMI patients with fQRS is significantly poorer than that of patients without fQRS,so fQRS possesses important predictive value for its prognosis.
