Filter by: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.
Immediate release (IR) tacrolimus peaks in the first two hours after administration. These peak levels are influenced by CYP3A5 expression with expressors requiring higher total daily doses with higher peak levels compared to non-expressors. Tacrolimus XR (Envarsus) is a once daily formulation with delayed absorption and lower peak levels while maintaining similar trough levels as seen with IR tacrolimus. A randomized trial of conversion from IR tacrolimus to tacrolimus XR in kidney transplant recipients have shown similar efficacy and adverse events between the two groups but no improvement in estimated GFR. However, urinary biomarkers of acute kidney injury associated with changes in tacrolimus dosing may be more sensitive then serum creatinine. The objective of this study is to assess renal tubular injury in heart transplant recipients who are converted from immediate release to tacrolimus XR. The hypothesis is that the delayed absorption and lower peak levels of tacrolimus XR will lead to less tubular injury and improved renal function without increased risk to the heart allograft.
Cardiac allograft vasculopathy is a common complication affecting heart transplant patients. This condition causes narrowing of the heart arteries leading to graft dysfunction. The research team is investigating whether early antiplatelet therapy post heart transplant can prevent the development of CAV. This study will determine the feasibility of a large multicenter randomized placebo-controlled trial to answer this question.
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.
The Portable Organ Care System (OCS™) Heart for Resuscitating, Preserving and Assessing Hearts Donated after Circulatory Death Continued Access Protocol (OCS DCD Heart CAP)
Coronary allograft vasculopathy (CAV) is diffusely accelerated atherosclerosis of a transplanted heart. Evolocumab (repatha) is an FDA-approved drug for lowering LDL in patients who have not received a heart transplant. This drug works as a PCSK9-inhibitor. The primary objective of this study is to measure the impact of PCSK9-inhibitors on serum LDL in heart transplant patients with CAV after 12 weeks compared to baseline.
The OCS™ Heart System will be used to preserve and assess donor hearts that do not meet current standard donor heart acceptance criteria for transplantation in this continued access protocol.
To evaluate the effectiveness of the OCS Heart System to resuscitate, preserve and assess hearts donated after circulatory death for transplantation to increase the pool of donor hearts available for transplantation.
The purpose of this research study is to see if a study drug called Tocilizumab will, when given with standard anti-rejection medicines, lead to better heart transplantation outcomes at 1 year after the transplant. Specifically, the investigators will evaluate whether taking tocilizumab leads to less rejection, less development of unwanted antibodies, and better heart function.
