Assessment of the Predictive Value of Anti-beta1AR and Anti-L-CaC Antibodies in the Evolution to Dilated Cardiomyopathy in Patients With Acute Viral Myocarditis
China300 participantsStarted 2024-12-17
Plain-language 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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
