Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and over with a confirmed diagnosis of cardiomyopathy or myocarditis, as well as those with a family history of cardiomyopathy.

Probably not a fit

Patients with a confirmed history of coronary artery disease or primary valvular heart disease may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study utilizes The Heart Hive, an international online registry for patients with clinically diagnosed cardiomyopathy or myocarditis, as well as those with a family history of these conditions. Participants will provide self-reported demographic and health data, which will be collected and analyzed over time. The study will recruit patients with dilated (DCM) and hypertrophic (HCM) cardiomyopathy for an observational study that includes genetic analysis and validation of self-reported diagnoses against medical records. The pilot phase aims to validate the approach with 200 patients, focusing on the genetic architecture of these conditions.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of cardiomyopathy and myocarditis, leading to improved diagnosis and treatment options for patients.

How similar studies have gone: Other studies utilizing patient registries and genetic analysis have shown promise in advancing understanding and treatment of cardiomyopathies, making this approach both relevant and potentially impactful.
