An observational study in Heart Transplantation, Dilated Cardiomyopathy (DCM) and Hypertrophic Cardiomyopathy (HCM), sponsored by University Hospital, Essen. Recruiting at 1 site in Germany. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-01-22.

The goal of this observational study is to pursue a multimodal approach to identify the molecular signatures and immune signalling molecules of various myocardial diseases and thereby contribute to improving diagnosis and therapy.
The main aim is:
-Identification of molecular profiles (e.g., proteome, lipidome, metabolome) and immune signalling profiles that are specifically associated with different myocardial diseases and the post-heart transplantation course.
Participants already receiving an endomyocardial biopsy as part of their regular medical care will be enrolled. An additional biopsy sample will be taken for the above mentioned research.
The proposed study aims to pursue a multimodal approach to identify the molecular signatures and immune signalling profiles of various myocardial diseases and thereby contribute to improving diagnosis and therapy. In the context of a clinically indicated endomyocardial biopsy (EMB), an additional EMB will be performed. This sample will be further analyzed using, among other methods, multi-omics, immune signalling analysis and nuclear cardiology analyses. These analyses are intended to enable the identification of genetic mutations, inflammatory gene expression patterns, immune signalling and protein alterations in myocardial diseases such as cardiomyopathies, myocarditis, and cardiac amyloidosis. Furthermore, the results will be correlated with established clinical parameters and biomarkers in order to identify novel diagnostic markers.
255 studies on the registry are indexed under Cardiomyopathy, Dilated; 66 are open to participants now.
This study's planned enrollment of 216 is below the median of 245 across 96 observational studies indexed under Cardiomyopathy, Dilated.

All patients receiving an endomyocardial biopsy after routine clinical indication will be enrolled. The identification of molecular profiles from the obtained endomyocardial biopsies (EMBs) represents an exploratory research approach that does not allow for an exact sample size calculation. Considering the heterogeneity of the collected EMBs, and particularly the fact that EMBs are often performed for the differential diagnosis of various rare myocardial diseases, an adequately large study population is necessary to capture rare phenotypes. The planned cohort will include 40 patients each from the main groups: unclear cardiomyopathy, suspected (ICI-)myocarditis, suspected cardiac storage disease, and post-heart transplantation surveillance. Thus, a total of 160 EMBs are targeted for multi-omics analysis.The secondary endpoint of the study allows for a sample size estimation of 56 EMBs for the subgroup of cardiac amyloidosis (calculation according to the full proposal).

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
