摘　　要：目的探究心肌梗死患者心电图QRS波宽度与心肌损伤的相关性分析。方法收集我院2020年2月~2023年2月收治的心肌梗死患者131例临床资料。依照心电图QRS波宽度分为QRS波宽度增加组(QRS波宽度≥120ms,72例)和QRS波宽度正常组(QRS波宽度<120 ms,59例)。比较一般资料、cTnI、CK-MB、Myo水平,分析患者心电图QRS波宽度与心肌损伤的相关性。结果两组的一般资料差异不显著,P均>0.05;QRS波宽度增加组心肌损伤相关指标cTnI、CK-MB、Myo均高于QRS波宽度正常组,差异显著,P均<0.05;心肌梗死患者心电图QRS波宽度与心肌损伤相关指标cTnI、CK-MB、Myo均呈显著正相关,P均<0.05。结论心肌梗死患者心电图QRS波宽度与心肌损伤密切相关,与cTnI、CK-MB、Myo水平均呈显著正相关。心电图QRS波宽度增加可能提示心肌梗死患者发生心肌损伤。Objective:To explore the correlation between electrocardiogram QRS wave width and myocardial injury in pa-tients with myocardial infarction.Methods:The clinical data of 131 patients with myocardial infarction admitted to the hospital from February 2020 to February 2023 were collected.According to the QRS width of electrocardiogram,the patients were divid-ed into an increased QRS width group(QRS width≥120 ms,72 cases)and a normal QRS width group(QRS width<120 ms,59 cases).The general data,cTnI,CK-MB and Myo levels were compared,and the correlation between QRS wave width of electro-cardiogram and myocardial injury was analyzed.Results There was no significant difference in general data between the two groups(P>0.05).The myocardial injury related indexes cTnI,CK-MB and Myo in the increased QRS width group were higher than those in the normal QRS width group,and the difference was statistically significant(P<0.05).QRS wave width was posi-tively correlated with cTnI,CK-MB and Myo in patients with myocardial infarction(all P<0.05).Conclusion QRS wave width is closely related to myocardial injury in patients with myocardial infarction,and it is positively correlated with cTnI,CK-MB and Myo levels.Increased QRS wave width may indicate myocardial injury in patients with myocardial infarction.
