Active clinical trials for "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 evaluates the diagnostic performance of 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) with rest perfusion imaging for the diagnosis of myocarditis. Patients with clinical suspicion of myocarditis will be recruited and undergo a rest myocardial perfusion scan and a FDG PET/CT scan following a myocardial suppression protocol.

The study will analyze the prevalence of cardiac involvement of health care workers from the University Hospital of Salamanca (HUSA) who have overcome SARS-CoV-2 infection. Participants will undergo a clinical evaluation, electrocardiogram (EKG), cardiac magnetic resonance (CMR) and blood analysis including NT-proBNP, troponin, cellular and humoral immunity and genetics.

Myocardial injury, as assessed by elevation of cardiac troponins (Tnc), is frequent among patients with COVID-19. Although rare autopsy cases reported COVID-19 related myocardial inflammation, the origin of Tnc elevation is unknown to date. Several cardiac causes, such as myocarditis, non-ischemic myocardial injury (NIMI), or myocardial infarction (MI) may lead to Tnc kinetic. Our work will test the hypothesis that during SARS-Cov2 infection, the elevation of cardiac biomarkers could be linked to the occurrence of myocarditis.

The purpose of the present study was to investigate ECG findings of patients with acute myocarditis, ECG findings associated with fulminant myocarditis, and the characteristics of ST-elevation on admission.

Depersonalized multi-centered registry initiated to analyze dynamics of non-infectious diseases after SARS-CoV-2 infection in population of Eurasian adult patients.

In this study, the investigators analyze the clinical characteristics and prognosis of patients with acute myocarditis in South Korea

The purpose of this study is the assess the diagnostic performance of magnetic resonance imaging in patients with suspected myocarditis by applying different imaging sequences at different MR scanners

The wearable cardiac defibrillator (WCD) is an alternative to the implantation of cardioverter defibrillator (ICD) for patients at high risk for sudden cardiac death (mostly bridging therapy). The Cologne register of wearable defibrillator (CRWD) is a prospective register for all patient with an indication of wearable defibrillator.

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.
