Filter by: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 cluster of differentiation antigen 80 (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 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computerized tomography (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 RNA sequencing.
Primary myocardial involvement is common in scleroderma, effected to pericardium, vascular, conducting defect and especially myocardium. Cardiac MRI is widely used for assessment of cardiac involvement in scleroderma, both structural and functional pathology. Cardiac MRI has a diagnostic accuracy of 85% for the detection of myocardial inflammation. Nowadays, the treatment of myocardial inflammation in scleroderma is uncertain. The investigator's study aims to define the cardiac outcome after moderate dose steroid therapy in the patients who have myocardial inflammation detection by cardiac MRI.
This is a joint project by Sahlgrenska University Hospital: Sahlgrenska, Östra and Mölndal. Our objective is to diagnose and map patients with well phenotyped cardiomyopathies (CMP) including in depth clinical and molecular phenotyping to enable earlier and specific treatment. The project will serve as: 1. resource for diagnostic and therapeutic trials 2. common biomaterial bank 3. resource for detailed molecular analyses on patients' biomaterials and patient specific symptoms and examination results
Patients with acute myocarditis (AM) usually experience spontaneous healing, but a considerable percentage of them evolve towards chronic long-term cardiac impairment. The evolution towards dilated cardiomyopathy (DCM) occurs in a subtle manner, frequently after an initial recover that mimics complete healing. Differences in the course of the disease may reflect the course of underlying myocardial inflammation related to viral clearance or persistence and to the following autoimmune response. Cardiac magnetic resonance (CMR) mapping parameters have been developed for the quantification of edema and necrosis, showing high diagnostic accuracy. No mapping parameter has been developed for the assessment of the third Lake Louise criteria, namely the hyperemia, and, furthermore, their prognostic role is not completely understood. The study hypothesis is that the early-enhanced T1 mapping parameter may have great diagnostic accuracy for myocarditis, and that a short-term monitoring with a complete CMR protocol at 2 month after symptoms onset may identify the subgroup of patients at high risk of progression towards DCM. The results of this study will help to significantly improve diagnostic performances of CMR and may help to manage patients with AM.
Presentation of myocarditis is heterogeneous, often ranges from being asymptomatic, to chest pain, dyspnoea, palpitations, and even sudden cardiac death. Diagnosing myocarditis is challenging with no current uniform clinical gold-standard. CMR is a key investigative tool, however the predictive value of CMR features is unknown. In this study we assess 670 consecutive patients with suspected myocarditis who were referred for CMR between 2002 and 2015 at the BWH. CMR features such as late gadolinium sizing, T1 mapping, extracellular volume fraction assessment, strain analysis (feature tracking), clinical data, labortory tetsings and electrocardiogramm are linked to the outcome in order to assess its predictive value.
Immune checkpoint inhibitors (ICIs) might have high grade immune-related adverse events (irAEs) on the cardio-vascular system. This study investigates reports of cardio-vascular toxicity with treatment including anti-PD1, Anti-PDL-1, and Anti CTLA4 classes using the World Health Organization (WHO) database VigiBase.
Infectious myocarditis are frequent, most of the time viral and can evolve to cardiac insufficiency. The diagnosis is difficult because they can mime an acute coronary syndrome. Approximately 10 % of patients with acute infarction suspected, have a normal angiography, and half of them has in fact a myocarditis, as showed studies of cardiac MRI among which some realized in our department . However, anomalies observed in MRI are not specific and it is necessary to use multiple criterions. A new radiopharmaceutical, the 68Ga-DOTATOC, specific of somatostatin's receptors which are over expressed by the inflammatory cells, has recently showed the capacity to identify myocarditis, but only in a small group of 6 patients. The investigators make assumptions: 1. this radiopharmaceutical is enough sensitive to detect most of the acute inflammatory myocarditis which are identified by the MRI and 2. it could maybe allow to identify myocarditis with a persistent subacute or chronic inflammation, which are difficult to identify with cardiac MRI, and it would be a new information able to guide the medical decision. Primary objectif: to determine if PET with 68Ga-DOTATOC is enough sensitive to identify myocarditis in acute inflammatory phase by hospitalized patients with suspected acute infarction and with normal angiography and who have a high probability of myocarditis identified by MRI. Disease prevalence will be close to 100 % at baseline Secondary objectives: 1. Estimate the frequency of inflammatory forms (subacute or chronicle), with a 68Ga-DOTATOC PET at 3 to 5 months from baseline, when classic signs of acute inflammatory generally disappeared (CRP, Troponin-I, myocardial oedema in MRI). 2. Analyze the concordance of the results of 68Ga-DOTATOC TEP by two readers
This is a retrospective cohort study to assess the clinical outcome of patients with fulminant myocarditis using "Life-support Based Comprehensive Treatment Regimen" and conventional therapy. In the present study, participants receive various treatment as part of routine medical care without any assignment of specific interventions to them. The process of treatment during hospitalization were recorded in medical chart and was reviewed by independent research personnel.
The investigators performed a retrospective, single-center observational study, and the participants with acute fulminant myocarditis were included.Then, the investigator analyzed the risk factors of in-hospital death in these participants with acute fulminant myocarditis.
