An Arrhythmia Risk Stratification and Genetic Trial
CardiomyopathiesPrimary3 moreThe prospective EUTrigTreat multi-center study is an observational, advanced diagnostics and genetic risk stratification trial in patients with standard indications for ICD treatment, with and without myocardial infarction in their history. Its aims are fourfold: 1) To accurately risk stratify a large cohort of implantable cardioverter-defibrillator (ICD) patients for ICD shock risk and mortality using traditional risk markers as well as genetic markers 2) To find a link between repolarization biomarkers and genetic markers of calcium metabolism. 3) To compare invasive and noninvasive electrophysiologic (EP) testing systematically 4) To assess temporal changes of typical noninvasive risk stratifiers and their prognostic implication. In five European academic clinical centers, 700 ICD patients are prospectively enrolled (optionally the number of enrolled patients may be expanded to 1000 patients). Comprehensive non-invasive risk stratifying ECG diagnostics including beat-to-beat variability of repolarization (BVR) are applied, and candidate genes associated with malignant arrhythmias are analyzed. Programmed electrical stimulation is performed to test for inducibility of malignant ventricular arrhythmias and BVR. In a subset of patients, electrophysiologic studies include recording of monophasic action potentials (MAP) from the right ventricle for assessment of restitution properties. Non-invasive risk stratifying ECG methods are repeated annually. Outcome (mortality, ICD shocks) will be assessed until September 2014.
Characterization of Obesity-related Cardiomyopathy Through Exploration of Human Atrial Trabeculae...
ObesityHeart FailureThe investigators aim to explore obese cardiomyopathy by studying contractile twitch force, sarcomere sensitivity to calcium and mitochondrial function in atrial myocardial samples of patients grouped according to their body mass index, i.e. normal weight, overweight and obese.
Prediction of ARrhythmic Events With Positron Emission Tomography
Ischemic CardiomyopathyHibernating Myocardium2 moreThe hypothesis of PAREPET is that hibernating myocardium (viable myocardium with reduced resting flow) and/or viable but denervated myocardium can predict the risk of sudden death in subjects with ischemic cardiomyopathy.
Insertable Cardiac Monitors in Hypertrophic Cardiomyopathy
Hypertrophic CardiomyopathyHypertrophic cardiomyopathy (HCM) is associated with sudden cardiac death and an increased risk of atrial fibrillation and subsequent embolic event. An insertable cardiac monitor will provide data on cardiac rhythm over a period of 18 months. This will provide an extended monitoring far longer than 24-48 hours of Holter monitoring as is currently usual care. Therefore, detection of arrhythmias could be used in risk stratification and decision-making with regard to offer an implantable defibrillator and anticoagulants.
Quantitive LGE Mass in Prediction of SCD in NICM Patients With Severe Cardiac Dysfunction
CardiomyopathyThe purpose of this study is to establish a quantitative LGE mass based scoring system (including LGE mass on cardiac magnetic resonance , clinical features, specific medical histories, et al) for risk prediction of sudden cardiac death in non-ischemic dilated cardiomyopathy patients with reduced left ventricular ejection fraction
Influence of Severe Heart Failure to Function and Molecular Biological Parameters of Catabolism...
Heart FailureIschemic Myocardiopathy1 moreProject aim is to quantify the influence of a severe therapy-refractory heart failure caused by ischemic or dilative myocardiopathy on the function of the diaphragm, its molecular biological parameters and on the M. vastus lateralis. The control group consists of patients with coronary artery disease (CAD) and normal left ventricular ejection fraction indicated for coronary artery bypass graft surgery (CABG) Differences in the geneses of heart failure (ischemic vs. dilative cardiomyopathy) will be evaluated during analysis. The ubiquitin-proteasome signaling pathway is considered as a central issue for the mechanism of the analyses muscle catabolism.
The Impact of Infectious Disease on QT Segment
SepsisPneumonia2 moreSepsis related to the development of cardiac complications. However, the investigators understanding regarding this condition remains incomplete. Possible explanations raised include coronary perfusion decrease, activation of the coagulation system and release of inflammatory mediators, including endotoxins, cytokines and others. In this study the investigators wanted to examine the impact of any infectious disease, (not necessarily Pneumonia), on the QT interval in patients hospitalized for acute infectious disease.
Role of the Wearable Cardioverter Defibrillator in Tachycardia Induced Cardiomyopathy
Tachycardia-induced CardiomyopathyThe purpose of this current study is to prospectively enroll consecutive patients hospitalized with newly diagnosed severe left ventricular dysfunction (LVEF ≤ 35%) for which the likely etiology is uncontrolled atrial fibrillation or high burden of ventricular ectopy. Patients completing their established in-hospital treatment plan with rate or rhythm control, will be discharged with a WCD following informed consent and detailed counseling by healthcare personnel for a time-period of up to 3 months until reassessment of LVEF and the need for ICD implantation.
Intraventricular Stasis in Non Ischemic Dilated Myocardiopathy
Dilated CardiomyopathyThrombosis1 moreThis study is designed to quantify the ventricular stasis in patients with non-ischemic dilated cardiomyopathy by post-processing of 2D color Doppler echocardiography images in order to establish the relationship between quantitative variables of intraventricular stasis and the prevalence of silent embolic events and/or intraventricular mural thrombosis determined by magnetic resonance.
The Influence of Atorvastatin on the Parameters of Inflammation and the Function of Left Ventricle...
Dilated CardiomyopathyThe aim of the study was to assess of the influence of atorvastatin on selected indicators of an inflammatory condition, function of the left ventricle and factors affecting the occurrence of undesired events like rehospitalizations and mortality in patients with dilated cardiomyopathy.
