Tocilizumab in Cardiac 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.

Belatacept in Heart Transplantation

This is a phase 2, prospective, multi-center, open-label clinical trial. Sixty-six (66) primary heart transplant recipients will be randomized (1:2) to receive either standard-of-care, tacrolimus-based immunosuppression, or a belatacept-based regimen with gradual tacrolimus withdrawal over 9-months post-transplant. Both study arms will receive CellCept® (mycophenolate mofetil- MMF) or Myfortic® (mycophenolate sodium). Corticosteroids will be continued throughout the study in the belatacept arm. The primary objective is to evaluate whether NULOJIX® (belatacept), when implemented with gradual tacrolimus withdrawal over 9 months, is safe with respect to preventing the composite endpoint of acute cellular rejection (ACR) \>= International Society of Heart and Lung Transplantation (ISHLT) 2R, hemodynamic compromise rejection in the absence of a biopsy or histological rejection, re-transplantation, and death at 18 months post-transplant.

MCNAIR Study: coMparative effeCtiveness of iN-person and teleheAlth cardIac Rehabilitation

Cardiac rehabilitation is a medically recommended program for patients with certain heart conditions. It includes exercise training, health education, and counseling. Unfortunately, many patients do not participate in cardiac rehabilitation. Some find it challenging to attend the in-person sessions. This study aims to compare two methods of delivering cardiac rehabilitation: in-person and through telehealth. The investigators want to know if the effects of these two programs are alike and if certain individuals benefit more from one program over the other.

Effect of Non-Surgical Periodontal Therapy on Inflammation in Heart Transplant Recipients

Heart transplant recipients frequently exhibit chronic low-grade systemic inflammation, which can contribute to allograft dysfunction and cardiovascular complications. Periodontitis, a chronic inflammatory disease of the tooth-supporting tissues, is a modifiable but often overlooked source of this inflammatory burden. This prospective study evaluated whether non-surgical periodontal therapy (NSPT) - comprising full-mouth debridement and oral hygiene instruction - could reduce systemic inflammatory markers in clinically stable heart transplant recipients. Adults who had undergone heart transplantation at least one year earlier and presented with gingivitis or periodontitis underwent a comprehensive periodontal examination and blood sampling for high-sensitivity C-reactive protein (hs-CRP), leukocyte count, hematocrit, and platelet count. Participants then received NSPT, with periodontal and hematological parameters reassessed three months later. Findings from this study may clarify whether periodontal therapy represents a useful adjunctive strategy for reducing systemic inflammatory burden in this medically complex population.

Non-invasive Prediction of EArly Cardiac rEjection

Acute rejection remains a major cause of morbidity and mortality in pediatric patients after heart transplant. In order to screen for rejection, most centers perform heart catheterizations with endomyocardial biopsies frequently in the first year post transplant and then every 1-2 years thereafter; these biopsies are associated with complications, can cause significant anxiety in patients and family members, and are a significant cost for the healthcare system. This project will evaluate non-invasive methods of detecting rejection using cardiac magnetic resonance imaging and blood testing with a goal to reduce the required number of cardiac catheterizations.

Non-Intubated Anesthesia for Adult Heart Transplantation

This prospective, multicenter, randomized controlled trial aims to evaluate whether non-intubated spontaneous ventilation anesthesia (NISVA) supported by a supraglottic airway can reduce cardiopulmonary complications and promote postoperative recovery in adults undergoing isolated orthotopic heart transplantation. Approximately 220 participants will be randomly assigned in a 1:1 ratio to either the NISVA group or the conventional endotracheal general anesthesia group. The study will primarily evaluate a cardiopulmonary composite endpoint within 30 days after transplantation. Postoperative invasive mechanical ventilation duration, pulmonary function recovery, intensive care unit length of stay, and other postoperative recovery outcomes will also be assessed. Participants will be followed during hospitalization and at 30 days, 3 months, and 1 year after transplantation to evaluate cardiopulmonary function, safety, postoperative recovery, rehospitalization, and survival.

Seeking Objectivity in Allocation of Advanced Heart Failure (SOCIAL HF) Therapies Trial

The primary goal of this study is to assess real-world effectiveness and implementation of an evidence-based multi-component strategy to reduce disparities in the allocation rate of advanced heart failure therapies, heart transplants and ventricular assist devices. This study proposes to implement evidence-based strategies that reduce unequal and unethical decision-making towards patients, replace subjective evaluations with objective criteria, and improve group dynamics in a randomized cluster trial. Our rigorously designed trial will inform national guidelines for advanced heart failure therapy allocation, and data are likely to be generalizable to other organ replacement treatments and advanced chronic disease decision-making processes across populations.

AERIAL Trial: Antiplatelet Therapy in Heart Transplantation

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.

Randomized Trial of SGLT2i in Heart Transplant Recipients

Heart transplant (HTx) is an established therapy for advanced heart disease that restores quality of life and improves survival. However, due to preexisting comorbidities combined with the immunosuppressive therapies required after transplantation, HTx recipients remain at high risk for kidney, cardiovascular (CV), and metabolic disease. Large randomized clinical trials have recently shown that sodium-glucose cotransporter 2 inhibitors (SGLT2i) have potent kidney protective and CV benefits in many populations of patients with chronic kidney disease (CKD), CV disease and/or diabetes. SGLT2i have not been studied prospectively in HTx recipients, which represents a barrier to their use in this population. In this multicenter randomized controlled trial in Veterans with HTx, investigators will evaluate the potential benefits of empagliflozin on kidney function, cardiometabolic risk, erythropoiesis, and functional status. A total of 200 Veterans will be randomly assigned to receive either empagliflozin 10 mg daily or a matching placebo for 12 months.
