Rejection Heart Transplant
Conditions
Brief summary
This study will analyze extracellular vesicle (EV)-derived protein profiles in heart transplantated patients during the first 15 months post-transplantation to investigate, if there are distinct EV-derived proteins or protein patterns that allow early and reliable diagnosis of acute cardiac allograft rejection. Additionally, it will explore temporal changes in the EV-derived protein profile during the early postoperative period irrespective of acute allograft rejection, and will investigate, if there are correlations between EV protein markers and imaging findings.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Identification of an extracellular vesicle-derived biomarker or biomarker pattern to diagnose endomyocardial biopsy-proven acute cellular or antibody-mediated cardiac allograft rejection | From entrollment to the end of study participation at 15 months | Change of the level of at least one EV-derived biomarker in the blood plasma of cardiac allograft recipients with endomyocardial biopsy-proven acute cellular or antibody-mediated cardiac allograft rejection compared to those with no rejection at the time of blood sampling. |
