Filter by:The overall hypothesis of this study is that subtle interactions between structural (substrate) and functional (trigger) abnormalities of the heart, some of which are genetically-determined, can be used to identify patients at high risk of sudden cardiac death (SCD). Such information may be used to better define patients most likely to benefit from replacement of an internal defibrillator (ICD). The prospective, observational study to enroll, categorize and follow patients who receive an ICD pulse generator replacement for primary prevention of SCD (PROSe-ICD) was established to : 1. to gain a better understanding of the biological mechanisms that predispose to SCD 2. to develop readily determined clinical, electrocardiographic, genetic and blood protein markers identify patients with an increased risk of dying suddenly
A severely reduced left ventricular ejection fraction is associated with increased mortality due to pump failure as well as to malignant ventricular arrhythmia. We hypothesize that targeted training may lead to improved survival and to increased parameters of risk stratification for malignant arrhythmia. Additionally, the training may lead to an improved psychological and mental condition of the patients
Sudden cardiac death is a tragic event that strikes all age groups and is unfortunately increasing in prevalence. Because it is difficult to predict those at highest risk, this study is designed to test the hypothesis that new imaging techniques (magnetic resonance imaging [MRI] and computed tomography [CT]) are useful for identifying factors which put people at high risk for sudden death.
Sudden cardiac death is in most cases triggered by ischemia-related ventricular tachyarrhythmias and accounts for 50% of deaths from cardiovascular disease in developed countries. Chronic elevation of indicators of coagulation activation has been found in patients with coronary heart disease , but a role of coagulation activation and proinflammatory state as a potential risk factor for ventricular fibrillation (VF) during acute myocardial infarction has not been investigated.
This is a prospective multicentric Italian study to evaluate the arrhythmic risk in myotonic dystrophy type 1.
