摘要
目的分析心电图QRS波时限与急性心肌梗死(AMI)患者左室射血分数(LVEF)、不良心脏事件(MACE)风险的相关性。方法选取我院2016年12月至2019年3月QRS波时限<100ms的AMI患者58例为<100ms组,并选取同期QRS波时限≥100ms的AMI患者58例为≥100ms组,对比两组N-末端脑肽钠前体、LVEF水平、心功能分级及MACE发生率,分析QRS波时限与N-末端脑肽钠前体、LVEF水平、心功能分级、MACE发生率关联性。结果<100ms组N-末端脑肽钠前体水平较≥100ms组低,LVEF水平较≥100ms组高(p<0.05);<100ms组心功能分级优于≥100ms组(p<0.05);<100ms组MACE发生率13.79%(8/58)较≥100ms组39.66%(23/58)低(p<0.05);经Spearman分析,QRS波时限与N-末端脑肽钠前体水平、心功能分级、MACE发生率呈正相关,与LVEF水平呈负相关(p<0.05)。结论AMI患者心电图QRS波时限越短,患者N-末端脑肽钠前体水平越低,LVEF水平越高,心功能越好,MACE发生率越低,心电图QRS波时限有助于评估患者预后,制定、实施针对性干预措施,并改善患者预后。
Objective To analyze the correlation between QRS duration and the risk of left ventricular ejection fraction(LVEF)and main adverse cardiac events(MACE)in patients with acute myocardial infarction(AMI).Methods From December 2016 to March 2019 in our hospital,58 patients with QRS duration<100 ms and AMI were selected as the group<100 ms,and 58 patients with QRS complex duration≥100 ms in the same period were selected as the group≥100 ms,and the two groups were compared with N-Terminal brain peptide sodium precursor,LVEF level,cardiac function grade and MACE incidence,and analyze the relationship between QRS complex time limit and N-terminal brain peptide sodium precursor,LVEF level,cardiac function grade and MACE incidence.Results The level of N-terminal brain peptide sodium precursor in the<100 ms group was lower than that in the≥100 ms group,and the LVEF level was higher than that in the≥100 ms group(p<0.05);The cardiac function classification of the<100 ms group was better than that in the≥100 ms group(p<0.05);The incidence of MACE in the 100 ms group was 13.79%(8/58)lower than 39.66%(23/58)in the≥100 ms group(p<0.05);Spearman analysis showed that the QRS complex time limit was related to the level of N-terminal brain peptide sodium precursor,heart Functional classification and incidence of MACE were positively correlated,and negatively correlated with LVEF level(p<0.05).Conclusions The shorter the QRS duration in patients with AMI,the lower the N-terminal pro-brain peptide sodium level,the higher the LVEF level,the better the heart function,and the lower the incidence of MACE,which can provide more information for clinical support.The prognosis of patients can be assessed according to the QRS duration,and targeted intervention measures can be formulated and implemented to improve the prognostic effect.
