Abstract:
Objective To investigate the value of QRS duration combined with serum myostatin(MSTN)in predicting the prognosis of chronic heart failure(CHF)in elderly patients.Methods A total of 167 elderly patients with CHF who were admitted to Dongtai People's Hospital from October 2018 to October 2022 were enrolled in this retrospective study.MSTN level was detected by ELISA,and QRS duration was recorded by DMS300-BTT01 electrocardiograph.The patients were followed up for one year.According to the occurrence of adverse cardiovascular events(MACE),they were assigned to group A(MACE occurred)or group B(no MACE).The influence factors for the occurrence of MACE in elderly CHF patients were investigated.The efficiency of the combination of various indexes in predicting MACE in elderly patients with CHF was analyzed by ROC curve.Results During one-year follow-up,MACE occurred in 36 patients(21.56%).MSTN level,QRS duration,LVEF,NYHA cardiac function grade,MuRF-1 and indoor conduction block in group A were superior to those in group B(P<0.05).Binary logistic regression analysis showed that MSTN,QRS duration,LVEF,NYHA cardiac function grade Ⅳ,indoor conduction block in the left bundle branch,and MuRF-1 were the influencing factors for MACE in elderly CHF patients(P<0.05).ROC curve showed that the sensitivities of LVEF,MSTN,QRS duration,NYHA cardiac function grade Ⅳ,MuRF-1,indoor conduction block in the left bundle branch,and their combination in predicting MACE in elderly patients with CHF were 75.00%,69.44%,72.22%,69.44%,66.67%,77.78%,and 91.67%,respectively,and the specificities was 74.81%,71.76%,73.28%,70.99%,68.70%,76.34%,and 91.60%.The combination of LVEF,MSTN,QRS duration,NYHA cardiac function grade Ⅳ,indoor conduction block in the left bundle branch,and MuRF-1 had a higher value in predicting the occurrence of MACE in elderly patients with CHF(P<0.05).MACE included myocardial infarction in 11 patients,cardiac death in 10 patients,all-cause death in 7 patients,recurrent heart failure in 4 patients,and fatal malignant arrhythmia in 4 patients.There were significant differences in QRS duration and MSTN level among different MACE patients(P<0.05).Conclusion MSTN,QRS duration,LVEF,NYHA cardiac function grade Ⅳ,indoor conduction block in the left bundle branch,MuRF-1 are the influencing factors for the occurrence of MACE in elderly CHF patients.There are significant differences in QRS duration and MSTN expression among different MACE patients.
