Cardiac imaging and biomarkers to help diagnose antibody mediated rejection after heart transplant
Official title: CARdiac Imaging and BIomarkers in the Diagnosis of Antibody Mediated Rejection in Heart Transplantation
Run by IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06774365 · Data updated 2026-11-12
This study tests whether MRI inflammation/fibrosis patterns and blood biomarkers can help identify antibody-mediated rejection in adults who recently received a heart transplant.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) who are between 1 and 15 years post-heart transplant, clinically stable, with LVEF > 40%, and undergoing routine DSA screening.
✕Probably not a fit
Patients with recent acute rejection, planned hospitalization for cardiovascular reasons, contraindications to CMR, or pregnancy may not benefit from this study.

What this trial studies
This multicenter observational study prospectively enrolls heart transplant recipients who are clinically stable but have donor-specific antibodies detected during routine AMR screening. Researchers will collect CMR imaging data to assess inflammation and fibrosis, along with blood-based biomarkers such as dd-cfDNA and T-reg populations, without altering standard clinical care. The goal is to determine how common fibrosis, edema, and abnormal T1 values are in patients with DSA and how often DSA is present among enrolled participants. Data are collected at study entry and through routine follow-up as part of standard practice, with treating physicians blinded to study-specific assay results. Interventions are not specified and follow current clinical guidelines.
Why it matters
Potential benefit: If successful, the study could improve understanding of noninvasive signals associated with AMR and help guide future diagnostic approaches for heart transplant recipients.
How similar studies have gone: Prior work in AMR surveillance suggests imaging and blood biomarkers can reflect rejection processes, but this exact combination in DSA-positive, clinically stable patients is relatively novel.
