摘　　要：目的观察急性非ST段抬高型心肌梗死(non-ST elevation myocardial infarction,NSTEMI)患者碎裂QRS波(fragmented QRS complex,f QRS)对临床预后的影响。方法回顾性分析2016年11月至2017年10月于我院治疗的122例NSTEMI患者的临床资料,依据患者入院时心电图检查结果,将伴有f QRS改变者归入f QRS组(61例),未伴有f QRS改变者归入非f QRS组(61例)。观察两组主要不良心脏事件(major adverse cardiac events,MACE)的发生情况、再次行PCI的治疗情况。结果两组心力衰竭、心脏性死亡、再发性心肌梗死、全因死亡等发生率相比,差异无统计学意义(P> 0. 05);与非f QRS组相比,f QRS组复发性心绞痛、总MACE发生率相对较高,差异有统计学意义(P <0. 05);与非f QRS组相比,f QRS组再次行PCI治疗者占比较高,差异有统计学意义(P <0. 05)。结论 NSTEMI患者若出现f QRS改变,将增加MACE发生风险,f QRS可作为预测该类患者预后的重要指标。Objective To observe the influence of fragmented QRS complex(fQRS)on clinical prognosis of patients with acute non-ST elevation myocardial infarction(NSTEMI).Methods Retrospective analysis was performed on the clinical data of 122 NSTEMI patients who had been treated in our hospital from November 2016 to October 2017.According to their ECG examination results on admission,those complicated by fQRS changes were classified into fQRS group(61 cases)while the ones without fQRS changes were divided into non-fQRS group(61 cases).The incidences of major adverse cardiac events(MACE)and efficacy of one more PCI were compared between the two groups.Results Among the two groups,the incidences of heart failure,cardiac death,recurrent myocardial infarction and all-cause death did not vary significantly(P>0.05).Compared with non-fQRS group,the incidence rate of recurrent angina pectoris and total incidence of MACE in fQRS group were higher,with statistically significant differences(P<0.05);the proportion of the patients undergoing PCI for twice was higher in fQRS group,also with statistically significant differences(P<0.05).Conclusion If fQRS changes are observed in NSTEMI patients,the risk of MACE will increase.fQRS can serve as an important index to predict the prognosis of NSTEMI patients.
