Summary

Background of the study Studies have shown that about one-third of patients with acute viral myocarditis (AVMC) eventually develop dilated cardiomyopathy (DCM), and that the autoimmune response to viral infection is key to the development of AVMC to DCM. A variety of antimyocardial autoantibodies (AHAs) are detected in the sera of patients with myocarditis. Among them, anti-β1AR antibodies are thought to contribute to the transition of AVMC to DCM possibly by promoting myocardial injury, cardiac remodeling, and impaired cardiac function. The role of anti-L-CaC antibodies in the evolution of AVMC to DCM is unknown, but they have been shown to induce ventricular tachycardia by increasing calcium inward flow and triggering early afterdepolarization, increasing the rate of sudden death and all-cause mortality in patients. Therefore, monitoring the levels of these antibodies may be useful in assessing the prognosis of patients with viral myocarditis. In this study, we propose to use a multicenter, prospective cohort study to further accurately assess the predictive value of these autoantibodies in the evolution of AVMC patients to DCM by detecting the serum levels of anti-β1AR antibodies and anti-L-CaC antibodies in AVMC patients and combining them with the clinical data and follow-up data, so as to provide prognostic biomarkers as well as targets for targeted interventions in AVMC.

Objective of the study A multicenter, prospective cohort study of the value of anti-β1AR and anti-L-CaC antibodies in the progression of AVMC patients to DCM, enrolling 300 AVMC patients, to further accurately assess the predictive value of anti-β1AR and anti-L-CaC antibodies in the progression of AVMC patients to DCM, and provide prognostic biomarkers and targeted interventions for AVMC. The study will provide prognostic biomarkers and targeted intervention for AVMC.
