NCT06741995 | Recruiting

• 1 other identifier: Jing yuan-DCM cohort study
• Study Type: observational
• Target: 1,000
• Locations: 1 country
• Sites: 1

Brief Summary

Background of the study The etiology of dilated cardiomyopathy (DCM) is complex and involves a variety of genetic, environmental, and immunologic factors. Autoimmune reactions (especially anti-cardiac autoantibodies) play an important role in the development of DCM. In recent years, several clinical studies have suggested that anti-β1AR and anti-L-CaC antibodies are associated with cardiovascular death, ventricular tachycardia, and sudden death in patients with DCM, which is of great value in the prognostic evaluation of DCM. However, most of these studies are single-center studies with small sample sizes and non-uniform testing methods. In this study, we will use a multicenter, prospective cohort study to follow up DCM patients in China for a period of 3 years, to further accurately assess the clinical predictive value of anti-β1AR antibody and anti-L-CaC antibody on the prognosis of DCM patients, and to provide epidemiological information as well as targeted therapeutic targets for DCM. Aims of the study A multicenter, prospective cohort study of anti-β1AR and anti-L-CaC antibodies for prognostic assessment of DCM patients, enrolling 1,000 DCM patients, to further accurately assess the prognostic value of the anti-AHA assay for DCM patients, and to provide targets for targeted treatment of DCM.

Study Population

Dilated cardiomyopathy (DCM) is a heterogeneous cardiomyopathy characterized by ventricular enlargement and reduced myocardial contractile function, with the exception of hypertension, heart valve disease, congenital heart disease, or ischemic heart disease at the onset. The clinical manifestations of dilated cardiomyopathy include progressive cardiac enlargement, reduced ventricular systolic function, heart failure, ventricular or supraventricular arrhythmias, conduction system abnormalities, thromboembolism, and sudden death.The etiology of DCM is complex and involves a variety of factors, including genetics, environment, and immunity.

You may qualify if:

• Age 18-75, any gender
• Diagnosed with dilated cardiomyopathy
• Subjects or their legal guardians are fully informed of the nature and risks of the study, participate voluntarily, and sign an informed consent form.

You may not qualify if:

• Serious uncontrolled infection at enrolment ("uncontrolled" is defined as signs and symptoms of infection that persist without improvement despite antimicrobial or other treatment)
• Uncontrolled active bleeding at enrollment
• Pregnancy or breastfeeding
• Combination of serious diseases affecting survival, such as tumors, with a life expectancy of less than one year
• Previous heart transplant or implantation of a cardiac assist device
• Patients with poor compliance who are unable to complete the full course of the study
• Other conditions (e.g., overstimulation, sensitivity, cognitive impairment, mental illness, or substance abuse/addiction) that, in the judgment of the investigator, may increase the risk to the subject or interfere with the clinical study and judgment of the results.

RECRUITING

Biospecimen

Retention: SAMPLES WITH DNA

Blood samples remaining after completion of routine clinical blood tests will be destroyed in accordance with the regulations of the hospitals in which the centers are located. The study doctor will take an additional 5ml of blood sample for AHA testing in addition to the routine clinical blood tests. Prior consent will be obtained from the patients before the blood samples are taken; after the completion of the study, the remaining blood samples from the additional 5 ml of blood samples will be approved by the Ethics Committee and used for future research on the mechanism of the development of DCM according to ethical requirements
