The overall goal of this project is to evaluate the clinical potential of fast quantitative myocardial tissue characterization using recently emerged Cardiac Magnetic Resonance Imaging (CMR) techniques to aid the diagnosis, treatment, and follow up of patients with myocardial diseases, such as ischemic heart disease, cardiomyopathies, and myocarditis.

Rheumatoid arthritis (RA) patients have a higher prevalence of subclinical atherosclerosis than the general population. In addition, RA patients experience higher rates of heart failure with preserved ejection fraction (HFpEF). There is evidence that myocardial mechanics and left ventricular diastolic function are more abnormal in the RA population and these changes occur earlier than in the general population. Recently a study suggested that RA patient have abnormal myocardial inflammation during a disease flare and that this is improved with anti-inflammatory treatment. This study is aimed at describing the prevalence of myocardial inflammation in patients during active RA disease flares and comparing that with RA patients who are in remission. Investigators hope to show that abnormalities in myocardial inflammation on PET imaging correlate with abnormalities in myocardial strain on echocardiography. Coronary CT will be performed to establish the presence of subclinical atherosclerosis and whether its presence affects changes in either myocardial inflammation or myocardial strain. The hypothesis is that patients with evidence of myocardial inflammation during the course of their RA disease are more likely to develop HFpEF during their lifetime. Although the present study will not be of a duration to assess outcome, it will provide descriptive data which may help guide future prospective study of patients with RA which may help guide appropriate cardiovascular testing in this high risk population.

This study aims to evaluate the effects of abatacept, a CTLA4-Ig fusion protein that binds CD80/86 (B7-1/B7-2), on subclinical myocarditis in rheumatoid arthritis (RA) through its effect on T cell subpopulations. RA patients without clinical CVD, biologic naïve, and with inadequate response to methotrexate (MTX), will undergo cardiac FDG PET/CT imaging to assess myocardial inflammation. Studies that investigate the impact of treatment on subclinical myocarditis in RA, a possible contributor to heart failure, while exploring potential underlying mechanisms (i.e., different T cell subpopulations), are needed for a better understanding of their relevance in the pathogenesis of heart failure in RA and survival improvement in these patients with excess risk for cardiovascular death. If the investigator hypothesis is confirmed and treatment with abatacept decreases and/or suppresses or prevents myocardial inflammation in RA, this will have multidisciplinary implications that could lead to changes in the current management of RA patients at high risk for cardiovascular events. Similarly, identification of T cell subpopulations in RA patients with myocardial FDG uptake will shed light into the underlying cellular mechanisms of myocardial injury and serve to guide the use of therapies that prevent their pathogenicity. The objectives of this study are to compare the change in myocardial FDG uptake in RA patients treated with abatacept vs adalimumab, and identify T cell subpopulations associated with myocardial FDG uptake in each treatment arm. RA patients will be randomized in an unblinded, 1:1 ratio to treatment with abatacept vs adalimumab. A cardiac FDG PET/CT will be performed at baseline and 16 weeks post-biologic treatment. T cell subpopulations associated with myocardial FDG uptake will be evaluated at both points in time with their transcriptional phenotype outlined by RNAseq.

This study evaluates positron emission tomography for the diagnosis of immune checkpoint inhibitor-related myocarditis. Immune checkpoint inhibitors have shown promising results in various malignancies however, several immune related adverse events have been described of which myocarditis carries the highest reported mortality. Diagnostic procedures, such as positron emission tomography, help find and diagnose myocarditis and provide functional or disease activity information as opposed to the largely structural/anatomic information.
