摘要 目的探讨心电图碎裂QRS波(fQRS)与急性心肌梗死(AMI)患者左室收缩功能的关系。方法采用病例对照研究设计,选取2021年1月至2023年10月于新余市人民医院进行治疗的AMI患者为研究对象,患者均进行常规心电图检查,心电图出现fQRS波群患者172例为A组,心电图出现病理性Q波而不出现fQRS波患者172例为B组,心电图出现fQRS波合并病理性Q波患者172例为C组。比较3组患者的左室收缩功能[包括左室射血分数(LVEF)、左心室舒张末内径(LVEDD)、左室舒张末容积(LVEDV)],GRACE评分、脂蛋白a和血尿酸水平及并发症发生情况。结果A组和C组LVEF水平低于B组,LVEDD和LVEDV水平高于B组(P<0.001)。A组和C组GRACE评分、脂蛋白a和血尿酸水平均高于B组(P<0.001)。A组和C组并发症发生率均高于B组(P<0.001)。结论fQRS波对于AMI患者心功能较为敏感,当AMI患者心电图中出现fQRS波时其左室收缩功能明显降低、并发症发生率增加,fQRS波可作为心肌梗死患者病情发展和预后的一个重要指标。
