Brief Summary:
The study objective is to identify the earliest changes in energy substrate metabolism in patients with cardiomyopathies (CMP). To achieve this objective, we plan first to test the hypothesis that patients with CMP present focal alterations in myocardial hyperpolarized [1-13C]pyruvate flux.
Detailed Description:
To measure the regional myocardial [1-13C]lactate to [13C]bicarbonate ratio as an index of mitochondrial oxidation and glycolysis coupling in the heart. Advanced cardiac MRI will be used to characterize cardiac morphology, function, myocardial blood flow and fibrosis.
Heart failure is a major source of morbidity and mortality in the United States. Multiple studies have demonstrated that development of heart failure is related to alteration in cardiac metabolism. Specifically, such changes include a shift from fatty acid oxidation to increased glucose utilization as energy source, with uncoupling of glycolysis and mitochondrial oxidation at the level of the pyruvate dehydrogenase complex. In human subject who were referred for LVAD placement, excised heart muscle samples exhibited significant increase in expression of pyruvate kinase M2 (PKM2) compared to subjects with normal LV function.
Additionally, mechanical unloading decreased PKM2 expression suggesting a correlation between pyruvate utilization and severity of heart failure. Such changes metabolic alterations appear to precede the actual structural changes and might be a possible target for future therapies, although the timeline of such changes remains to be elucidated. Currently, it is unknown whether different types of CMP have different metabolic signatures.

Brief Summary:
The purpose of this study is to develop prediction models that can prognosticate patients with sarcoidosis using clinical data and blood markers that can be obtained during a clinic visit.
Detailed Description:
The purpose of this study is to develop prediction models that can prognosticate patients with sarcoidosis using clinical data and biological markers that can be obtained during a clinic visit.
Primary Aim/Objective The primary objective of this study is to determine which clinical features measured during a routine clinic visit are risk factors for progression of pulmonary sarcoidosis over the follow-up period in adults with pulmonary sarcoidosis.
Secondary Aim/Objectives The secondary objective is to determine if blood biomarkers measured during a routine clinic visit can improve the risk assessment for progression of pulmonary sarcoidosis over the follow-up period.
The investigators will measure two types of blood markers to achieve this goal:
- Clinically available blood markers that are available in most clinical labs
- Blood proteins and gene expression that reflect interferon inflammation and are not currently available as tests in clinical labs

Brief Summary:
The primary aim is to test whether abatacept, as compared to placebo, is associated with a reduction in major adverse cardiac events (MACE) among participants hospitalized with myocarditis secondary to an immune checkpoint inhibitor (ICI). The primary outcome, MACE, is a composite of first occurrence of cardiovascular death, non-fatal sudden cardiac arrest, cardiogenic shock, significant ventricular arrythmias, significant bradyarrythmias, or incident heart failure.
Detailed Description:
This investigator-initiated randomized trial is being conducted to test whether abatacept, as compared to placebo, is associated with a reduction in MACE among participants who develop myocarditis after treatment with an ICI. Immune checkpoint inhibitors leverage the immune system to treat a wide variety of cancers. Myocarditis is an uncommon immune related adverse event (irAE) secondary to treatment with an ICI. The guideline recommended treatment for ICI myocarditis is cessation of the ICI and administration of corticosteroids. However, despite administration of corticosteroids, the rate of MACE with ICI myocarditis is high. Data from multiple independent international cohorts have shown that the rate of MACE with ICI myocarditis despite administration of corticosteroids ranges from 25-50%.For comparison, the rate of MACE with myocarditis unrelated to an ICI is <5%.
Abatacept is a selective co-stimulation modulator that inhibits T cell (T lymphocyte) activation by binding to CD80 and CD86, thereby blocking its interaction with CD28. This interaction provides a costimulatory signal necessary for full activation of T lymphocytes. In animal studies of ICI myocarditis, the administration of abatacept led to a reduction in cardiac immune activation and an increase in survival. In retrospective unpublished clinical data, the administration of abatacept to participants with ICI myocarditis on corticosteroids was associated with a reduction in risk of MACE. There are no prospective studies testing whether abatacept is effective among participants with ICI myocarditis. Therefore, the primary aim of this trial is to test in a randomized double-blind placebo-controlled study whether abatacept, administered concurrently with corticosteroids, is associated with a reduction in MACE among participants with recently diagnosed ICI myocarditis
