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.

Who should consider this trial

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.

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

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 performed: 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.

* Adult (age 18 and over),
* Males and Females,
* Capacity to provide informed consent,
* Patients with a confirmed diagnosis of cardiomyopathy or myocarditis,

* Patients with a confirmed history of coronary artery disease:
* who have been informed by their treating physician that their cardiomyopathy is secondary to their coronary artery disease, or
* who have undergone previous percutaneous coronary intervention or coronary bypass surgery
