Brief Summary: This trial was a single-center prospective cohort studyThe purpose of this clinical research is to evaluate the accuracy of combining multimodality MR Imaging with circulating exosomal miRNA expression to diagnose acute rejection in patients with heart transplantationthus it may be helpful for timely intervention to improve the patients prognosis
Detailed Description: Acute rejection AR after heart transplantation remains the major factor limiting long-term survival and an independent risk factor for chronic allograft vasculopathy Currently there remains no reliable non-invasive method to detect AR Multimodality magnetic resonance MR imaging shows accurate detection of myocardial damage such as interstitial cell infiltrates edema hemorrhage myocyte damagenecrosis and capillary stenosis or fragmentation It turned out that the indicators in both MR imaging and circulating exosomal miRNA showed difference between patients with and without AR in our initial research work Therefore we hypothesize that circulating exosomal miRNA may play an important role in the activation of signaling pathway in AR after heart transplantation which can be detected by multimodality MR imaging All transplant recipients receiving transplantation follow-up care in our center were approached In the present research we aim to combine multimodality MR imaging with circulating exosomal miRNA to explore a new evaluation methodology and platform for early and noninvasive detection of AR after heart transplantation We attempt to confirm contribution of circulating exosomal miRNA to myocardial damage of AR through biopsy-proven allograft rejection and animal heterotopic heart transplantation
