Active clinical trials for "Death, Sudden, Cardiac"

The purpose of this study is to determine whether a blunted heart rate response to regadenoson is an independent predictor of sudden cardiac death.

To prospectively evaluate if the analysis of genetic polymorphisms can be used to identify patients at risk of ventricular tachycardia. To evaluate the influence of ICD-based diagnostic information on the long term treatment and management of primary prevention ICD-patients.

The main purpose of this study is to investigate whether intravenous infusion of a lipid emulsion with a high content of n-3 polyunsaturated fatty acids can improve heart rate variability and ventricular repolarization and reduce ventricular arrhythmias in hemodialysis patients.

The aim of the study is to assess the negative predictive value of the T amplitude variance as a method for risk stratification for patients with an increased risk for SCD.

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

The goal of this study is to show the superiority in survival at hospital admittance and in neurological outcome on hospital discharge of continuous mechanical chest compression using LUCAS device versus manual chest compressions in patients who suffered an out-of-hospital cardiac arrest.

This is a prospective multicentric Italian study to evaluate the arrhythmic risk in myotonic dystrophy type 1.

To compare home use of an automatic external defibrillator (AED) to the use of local emergency medical system in treating survivors of sudden cardiac arrest.

The purpose of this study is to assess the risk of serious cardiac events, specifically ventricular tachyarrhythmia and sudden cardiac death (VT/SCD), associated with the use of domperidone in a population of patients with Parkinson's disease. The hypothesis for this study is that the risk of VT/SCD will be higher among domperidone users, especially at a higher dose. The investigators will conduct a retrospective population-based cohort study using health care databases in eight jurisdictions in Canada and the UK. The study cohort will be defined by the initiation of a new antiparkinsonian drug or a new diagnosis of Parkinson's disease. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the risk of VT/SCD in users of domperidone.

Serum Troponin levels pre- and postoperatively will be compared in patients receiving an entirely subcutaneous cardioverter-defibrillator.
