RESUMEN

Objective To investigate the relationship between fragmented QRS (fQRS) complex and the early left ventricular remodeling or heart function in patients with acute myocardial infarction(AMI).Methods A total of 76 patients with AMI hospitalized in CCU of the Second Hospital of Tianjin Medical University were enrolled in the study.Patients were divided into fQRS group (n=29) and non-fQRS group (n=47). The clinical data including ECG, laboratory indicators, coronary angiography results and real-time three-dimensional (RT-3D) echocardiography parameter were collected in two groups.The relationship between fQRS and baseline data,fQRS and RT-3D echocardiography parameter were analyzed.At the same time,the influencing factors of left ventricular remodeling and heart function were discussed in the study. Results Compared with non-fQRS group, left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume (LVESV)were significantly higher,and left ventricular ejection fraction(LVEF)was significantly lower in fQRS group(P<0.05).Several three-dimensional parameters including Tmsv16-SD(%)and Tmsv 16-Dif(%)were significantly higher in fQRS group than those in non-fQRS group(P<0.05).There were no significant differences in Tmsv 16-SD(ms),Tmsv 12-SD(ms),Tmsv 12-SD(%),Tmsv 6-SD(ms),Tmsv 6-SD(%),Tmsv 16-Dif(ms),Tmsv 12-Dif(ms),Tmsv 12-Dif(%),Tmsv 6-Dif(ms)and Tmsv 6-Dif(%)between two groups.Logistic regression analysis showed that fQRS and Gensini scores had effects on heart function.At the same time,fQRS was an independent predictor for left ventricular remodeling. Conclusion Left ventricular remodeling is more obvious in patients with acute myocardial infarction complicated with fQRS,and fQRS can predict left ventricular remodeling better.
