Filter by:Prospective cohort clinical study, registry-based, multicenter, national, with the consecutive inclusion of patients with a history of Heart Transplantation in Brazil. The clinical registry will involve the participation until 25 centers. Patients will be included up to 30 days after Heart Transplant surgery and will be followed for one year. Laboratory tests and clinical parameters wil be collected in two clinical visits (6mo and 12 mo). The outcomes evaluate will be the total hospitalizations and all-cause death. It is expected to include 730 patients with a 12-month follow-up from the day of the transplant surgery. The findings of the HESTIA Registry may guide the management of post-heart transplant patients, aiming at reducing morbidity and mortality within 12 months after heart transplant surgery.
This is an unblinded, randomized, controlled, two-arm interventional research study enrolling patients who are undergoing heart transplantation. The aim of the study is to determine whether patients at low risk of rejection can safely reduce the doses of their post-transplant immunosuppression medications using a combination of tests that include donor-specific antibodies (DSA), histology (looking at tissue from the donor heart), donor-derived cell-free DNA (AlloSure), and gene expression profiling (AlloMap). Eligible participants will be randomized in a 1:1 ratio into the HeartCare immune-optimization (intervention) arm or the corresponding observational (control) arm. AlloSure and AlloMap are the components of the HeartCare panel developed by CareDx.
This study aims to more accurately assess cardiac function, ventilation and exercise capacity in a non-invasive fashion, and to better characterize exercise intolerance in the setting of three populations of individuals with chronic diseases of childhood (acute lymphoblastic leukemia (ALL), chronic lung disease (CLD) of prematurity, and post-heart transplant (HT))
The aim of this study is to evaluat the impact of diabetes on cardiac function in patients with heart transplantation by multimodal imaging and analyse their prognosis.
The aims of this study are to 1. Assess the preoperative and postoperative atrial and ventricular structure and function comprehensively in heart transplantation; 2. Explore the early, accurately and non-invasively indicators for evaluating myocardial fibrosis in end-stage heart failure, as well detecting acute rejection (AR),coronary allograft vasculopathy(CAV) and adverse clinical events in heart transplant patients by using conventional and the advanced echocardiography.
The aim is to (1) establish a system of multimodal imaging technology; (2) jointly apply multimodal imaging technology to diagnose of cardiac allograft vasculopathy of heart transplantation; (3) construct a multimodal imaging technology prediction model of adverse events, screening the best non-invasive imaging prediction indicators.
This study is designed to determine if an innovative mobile health intervention designed to improve patient-provider communication can reduce unscheduled hospitalizations, and visits to the emergency department and ambulatory clinic in adult heart, liver, and kidney transplant patients.
