Correlation between maternally expressed gene 3 expression and heart rate variability in heart failure patients with ventricular arrhythmia.
Aim: The aim of the study was to analyse the correlation between maternally expressed gene 3 (MEG3) expression and heart rate variability (HRV) in heart failure patients with ventricular arrhythmia (VA).
Methods: A total of 130 heart failure patients, treated from July 2018 to March 2021, were prospectively selected and divided into a non-VA group (n = 85) and a VA group (n = 45) according to the presence or absence of VA. The correlations of serum MEG3 expression and HRV with cardiac function indicators were investigated by Pearson correlation analysis. Receiver operating characteristic (ROC) curves were plotted to assess the predictive value of MEG3, HRV and their combination for the occurrence of heart failure complicated with VA.
Results: The VA group had a higher left atrial diameter (LAD) and left ventricular end-diastolic diameter (LVEDD) but lower left ventricular ejection fraction (LVEF) and ratio of mitral early diastolic peak velocity (E) to late peak atrial filling velocity (A) (E/A) than the non-VA group (p < 0.05). The serum MEG3 expression was negatively correlated with: standard deviation of the average RR intervals calculated over five-minute segments in the 24-hour record (SDANN), SDANN index, standard deviation of normal-to-normal RR interval (SDNN) index, percentage of differences between adjacent normal RR intervals exceeding 50 ms (PNN50), root mean square of successive difference (RMSSD), low frequency (LF), high frequency (HF), very low frequency (VLF), LVEF and E/A (r < 0, p < 0.05). The serum MEG3 expression was positively correlated with LAD and LVEDD (r > 0, p < 0.05). The areas under the ROC curves of MEG3, SDANN, SDANN index, SDNN index, PNN50, RMSSD, LF, HF, VLF and their combination for the prediction of the occurrence of heart failure complicated with VA were 0.812, 0.731, 0.737, 0.689, 0.860, 0.783, 0.791, 0.856, 0.769 and 0.966, respectively.
Conclusion: MEG3 combined with HRV can effectively predict the occurrence of heart failure complicated with VA.
