Filter by:Myocarditis is a complex inflammatory disease, usually occurring secondary to viral infections, autoimmune processes or toxic agents. Clinical presentations are multiple, including chest-pain, heart failure and a broad spectrum of arrhythmias. In turn, outcome is largely unpredictable, ranging from mild self-limiting disease, to chronic stage and progressive evolution towards dilated cardiomyopathy, to rapid adverse outcome in fulminant forms. Subsequently, myocarditis is often underdiagnosed and undertreated, and optimal diagnostic and therapeutic strategies are still to be defined. This study, both retrospective and prospective, originally single-center and subsequently upgraded to multicenter, aims at answering multiple questions about myocarditis, with special attention to its arrhythmic manifestations. 1. Optimal diagnostic workflow is still to be defined. In fact, although endomyocardial biopsy (EMB) is still the diagnostic gold standard, especially for aetiology identification, it is an invasive technique. Furthermore, it may lack sensitivity because of sampling errors. By converse, modern imaging techniques - cardiac magnetic resonance (CMR) in particular - have been proposed as alternative or complementary diagnostic tool in inflammatory heart disease. Other noninvasive diagnostic techniques, like delayed-enhanced CT (DECT) scan or position emission tomography (PET) scan, are under investigation. 2. Biomarkers to identify myocarditis aetiology, predisposition, prognosis and response to treatment are still to be defined. 3. Arrhythmic myocarditis is largely underdiagnosed and uninvestigated. Importantly, myocarditis presenting with arrhythmias requires specific diagnostic, prognostic and therapeutic considerations. At the group leader hospital, which is an international referral center for ventricular arrhythmias management and ablation, a relevant number of patients with unexplained arrhythmias had myocarditis as underlying aetiology. The experience of a dedicated third-level center is going to be shared with other centers, to considerably improve knowledge and management of arrhythmic myocarditis. 4. The role of CMR, as well as alternative noninvasive imaging techniques, in defining myocarditis healing is a relevant issue. In particular, optimal timing for follow-up diagnostic reassessment is still to be defined, in patients with myocarditis at different inflammatory stages, either with or without aetiology-dependent treatment. 5. Uniformly-designed studies are lacking, to compare myocarditis among different patient subgroups, differing by variables like: clinical presentations, myocarditis stage, associated cardiac or extra-cardiac diseases, aetiology-based treatment, associated arrhythmic manifestations, diagnostic workup, and devices or ablation treatment.
Acromegaly is a disease characterized by excess growth hormone(GH) and insulin like growth factor(IGF)-1. Pituitary GH secreting adenoma is the major cause of acromegaly. Acromegalic cardiomyopathy is one of the leading causes of death in acromegalic patients. No efficient medicine is available for acromegalic cardiomyopathy until now and there were limited studies. Empagliflozin is proved to decrease the risk of heart failure in diabetic patients and independent of blood glucose control. We planed to evaluate the structure of heart by MRI before and after 6 months treatment with empagliflozin in acromegalic patients to investigate the effect of empagliflozin on acromegalic cardiomyopathy.
This is a prospective multi-center international registry. The objective of this registry is to collect prospective data on patients undergoing catheter ablation for Ventricular Tachycardia (VT) and Premature Ventricular Contractions (PVC). The registry will be used for clinical monitoring, research, and quality improvement purposes.
The study will investigate the stabilization effects of Tafamidis utilizing cardiac imaging cardiac magnetic resonance imaging (CMR). The investigators propose to pursue the following specific aims: 1. Utilize cardiac magnetic resonance to assess stabilization of ATTR after Tafamidis therapy based on extracellular volume mapping. 2. Investigate left ventricular myocardial mass, native T1, T2, and extracellular volume mapping after 12 month follow-up. 3. Utilize cardiac magnetic resonance feature tracking at baseline and at 12 month follow-up.
Acute stress-induced (takotsubo) cardiomyopathy or broken heart syndrome presents like a heart attack, classically is triggered by intense emotional or physical stress and can have serious health consequences. In the current study the investigators wish to establish whether there is a genetic predisposition making certain people more susceptible to this condition. This could also have implications for their families.
This is a prospective multicenter randomized open-label study aiming to assess whether endocardial or endocardial-epicardial ablation is superior to the standard approach (i.e., Antiarrhythmic drugs) in achievement of long-term ventricular tachycardia (VT) treatment success.
According to single-photon emission computed tomography, the left ventricular contractile and coronary flow reserve (CFR) will be assessed in patients with ischemic cardiomyopathy. According to these data, the criteria for predicting the effectiveness of complex surgical treatment of this pathology will be evaluated.
The primary objective of this pilot study is to document the percentage achievement in effective HR control (average nighttime HR < 70 bpm) during WCD use in a cohort of female patients with cardiomyopathy in an outpatient setting using continuous heart rate (HR) trends data from the WCD to optimize BB/ivabradine dosage, as compared to a prior historical control.
This study is designed to determine the efficacy and safety of colchicine in patients with chronic kidney disease.
Based on recent studies demonstrating SGLT2 inhibitors' favorable effects on cardiovascular outcomes especially for heart failure, the investigators hypothesize that sodium-glucose co-transporter-2 (SGLT2) inhibitor, ertugliflozin, is effective on reducing cardiac fibrosis in patients with nonischemic cardiomyopathy so the investigators try to examine this hypothesis in a single-center, double-blind, randomized controlled study using cardiac magnetic resonance (CMR). This study is a prospective, single-center, randomized, double-blind, two arm parallel group, placebo-controlled clinical trial involving patients with nonischemic cardiomyopathy. Patients meeting inclusion criteria without any exclusion criteria will be randomized 1:1 to ertugliflozin or placebo therapy, and cardiovascular functional assessment and clinical event follow-up will be undertaken.
