摘要
目的研究碎裂QRS波与急性心肌梗死急诊介入治疗后ST段回落不良的关系。方法选取急诊介入治疗急性心肌梗死患者90例,根据心电图有无破碎QRS波分为观察组(有破碎QRS波,n=50)和对照组(无破碎QRS波,n=40)。分析两组患者的心电图参数、实验室指标并统计Gensini评分与ST段回落率。结果有破碎QRS波患者心电图参数及肌酸激酶同工酶(creatine kinase,MB Form,CK-MB)、肌酸激酶(creatine kinase,CK)、肌钙蛋白(cardiac troponin I,c Tn I)等实验室指标和临床特征均显著高于无破碎QRS波患者,多因素回归分析结果显示,f QRS时限增量、术前f QRS导联数、c Tn I与术后ST段回落不良独立相关。结论 QRS碎裂波与行急诊介入治疗的ST段抬高型心肌梗死患者术后ST回落不良有关,急诊PCI术前心电图出现f QRS能够作为ST段回落不良的预测指标。
Objective To study the relationship between the post-treatment of fragmented QRS complexes(fQRS)and imperfect ST-segment resolution after interventional therapy in patients with acute myocardial infarction.Methods Accordingto the electrocardiogram(ECG)with or without fQRS,90 cases of acute myocardial infarction patients after emergency interventional therapy were divided into observation group(with fQRS,n=50)and control group(no fQRS,n=40).The electrocardiogram parameters of the two groups were analyzed,the laboratory indexes were analyzed and the rates of Gensini score and ST segment were calculated.Results The electrocardiogram parameters and laboratory indicators such as creatine kinase isoenzyme(CK-MB),creatine kinase(CK),troponin(cTnI)in patients with fQRS were significantly higher than that of patients without fQRS.Multiple factors regression analysis showed that the fQRS time increment,preoperativefQRS lead number,troponin were associated with imperfect ST-segment resolution.ConclusionsfQRS is associated with imperfect ST-segment resolution after emergency interventional therapy in myocardial infarction patients,fQRS in pre-emergency-PCI ECG can be predictor of imperfect ST-segment resolution.
