Summary

Pathological cardiac hypertrophy is characterized by abnormal cardiomyocyte metabolism, reduced myocardial contractility, and dysregulated synthesis of myocardial contractile proteins. This pathological process leads to progressive impairment of cardiac function and ultimately progresses to heart failure. Previous studies have demonstrated that PRMT5 exerts a significant inhibitory effect on heart failure, yet its clinical significance in the context of heart failure remains undefined. In this study, we hypothesized that serum PRMT5 may serve as a biomarker to predict cardiac structural parameters and functional indices. Therefore, we aim to analyse the correlation between serum PRMT5 levels and the following parameters-LVPWs, LVPWd, LVIDs, LVIDd, IVSTs, IVSTd, EF, FS, LVMi and RWT on the first day when participants are enrolled in this study.

Detailed description

The aim of this study is to collect blood samples from both healthy controls and heart failure patients and to clarify the correlation between serum PRMT5 levels on the first day of enrollment and cardiac ultrasound indicators. Serum PRMT5 levels are measured by means of enzyme-linked immunosorbent assay (ELISA). Left ventricular posterior wall thickness at end-systole (LVPWs), Left ventricular posterior wall thickness at end-diastole (LVPWd), left ventricular internal diameter at end-systole (LVIDs), left ventricular internal diameter at end-diastole (LVIDd), interventricular septum at end-systole (IVSTs) and interventricular septal septum at end-diastole (IVSTd) are measured on the first day of enrollment via echocardiography. Ejection fraction (EF), fractional shortening (FS), left ventricular mass index (LVMi), and relative wall thickness (RWT) are subsequently calculated based on LVIDd, LVPWd, and IVSTd values. Finally, the correlations between serum PRMT5 levels and the following indicators are analyzed: LVPWs, LVPWd, LVIDs, LVIDd, IVSTs, IVSTd, EF, FS, LVMi and RWT.
