Filter by:Following acute cardiovascular injury, inflammation is vital to activate reparative mechanisms. However, there is compelling evidence implicating excessive inflammation and dysregulated resolution in fibrosis, ventricular remodelling, and heart failure (HF). Recently, the anti-inflammatory agent colchicine reduced cardiovascular events after myocardial infarction (MI) compared to placebo, indicating that targeting inflammation in acute cardiovascular conditions is feasible. Several acute cardiovascular conditions are characterised by inflammation, including myocarditis, MI, and acute heart failure. However, there is large variability in definition, epidemiology, clinical presentation, pathophysiology, and natural history of acute inflammatory cardiovascular diseases. This relates, in part, to the difficulty in performing adequately powered studies. Clinical studies that include sufficient patients and extended observation periods are necessary to address some of these knowledge gaps. This registry aims to collate routinely collected clinical data on patients with acute cardiovascular diseases characterised by inflammation in an observational-based registry. By doing so, the investigators hope to understand the contribution of inflammation to the pathophysiology of acute cardiovascular disease, improve risk stratification, and identify potential novel therapeutic targets.
The efficacy and safety of Tofacitinib in patients with glucocorticoid resistant ICIs-related myocarditis: a single-arm, prospective, phase 2 trial
The aim of this study is to collect clinical data and biological specimens from patients with myocarditis and construct a predictive model for the prognosis of myocarditis.
The etiology and specific pathogenesis of many cardiovascular diseases such as coronary atherosclerosis, cardiomyopathy, atrial fibrillation, and stroke are still unclear. Improving diagnosis and treatment, clarifying the pathogenesis, and providing scientific basis for the prevention and treatment are hot research topics in the study of cardiovascular and cerebrovascular diseases. This study intends to collect clinical data and biological specimen data of patients with cardiovascular and cerebrovascular diseases who meet the inclusion and exclusion criteria, and use multi-omics technology to deeply understand the pathogenic mechanisms of cardiovascular and cerebrovascular diseases and provide new ideas for specific and individualized treatment of patients with cardiovascular and cerebrovascular diseases, to construct early predictive prognostic models and provide a basis for effective treatment of clinical practice in patients with cardiovascular and cerebrovascular diseases.
The goal of this observational study is to observe if ultra-sensitive troponins (us) measurement between 3 and 6 months after the acute event will be sensitive enough to dispense with all other examinations, particularly cardiac magnetic resonance imaging (MRI), in patients suffering from myocarditis. The investigators will collect patient events by telephone, once a year for 4 years.
Acquired inflammatory or infectious cardiac diseases, in pediatrics, include Kawasaki disease, myocarditis, and Covid-19-related Pediatric Multisystemic Inflammatory Syndrome (PIMS). These 3 inflammatory cardiac diseases have clinical, biological, and echographic similarities and differences. Nevertheless their modalities of monitoring, management and evolution are different. The investigators wish to retrospectively analyze biological and echocardiographic data of Kawasaki disease, myocarditis, PIMS patients managed at Nancy Children Hospital from January 1, 2017 to June 31, 2023. The primary objective of this study is to identify, for these 3 pathologies, the prognostic factors of initiation of inotropic support. The secondary objective is to identify the prognostic factors of degradation of ventricular function.
Myocarditis is an inflammatory disease of the heart, mostly caused by viruses. Patients with acute myocarditis are exposed to several complications: recurrence, ventricular arrhythmias (from 5 to 30%), heart failure (5-10%), death or heart transplantation (< 4%). To date, there is no specific treatment for myocarditis. Patient management only focuses upon empirical optimal care of arrhythmia and heart failure. There is a strong rationale for using colchicine in acute myocarditis: - the IL1 (Interleukin1) pathway plays a detrimental role in acute myocarditis. NLRP3 (NOD-like receptor family, pyrin domain containing 3) inflammasome assembly, and subsequent IL-1beta production, are profoundly inhibited by colchicine. - colchicine has been shown to improve cardiac outcomes in inflammatory cardiac disorders, including pericarditis, coronary artery disease, and post pericardiotomy syndrome. - In murine model of CVB3-induced myocarditis (coxsackievirus B3), colchicine improved myocarditis through reduction of NLRP3 activity. - Small case series with improvement of left ejection fraction in myocarditis following low-dose colchicine in addition to conventional heart failure therapy have been reported. With its pleiotropic anti-inflammatory effect in the pro-inflammatory cascade, reducing the myocardial damage and cell death induced during myocarditis, colchicine has the potential to reduce the risk of heart failure and ventricular arrhythmias. Finally, colchicine is a drug widely available, at low cost, and has a long and well-known safety record.
This is a prospective observational phase IV study of a novel, replication-deficient smallpox vaccine that has been recently been approved by FDA. The purpose of this study is to determine if there are any abnormalities detected by electrocardiographic testing and/or blood tests within 35 days of receiving the second dose of smallpox vaccine either alone or co-administered with other vaccines that may/may not be suggestive of myopericarditis.
