European Sleep Apnea and Sudden CArdiac Death ProjEct

Sleep ApneaSudden Cardiac Death2 more

The objective of ESCAPE-SCD Study is assessment of the effect of sleep apnea on sudden cardiac death risk and cardiovascular outcomes in patients with ischemic cardiomyopathy. The ESCAPE - SCD Study will address following specific study questions: Is obstructive sleep apnea (OSA) and/or central sleep apnea (CSA) an independent risk factor of sudden cardiac death (SCD) in patients with ischemic cardiomyopathy (ICM) indicated for ICD/CRT-D implant based on current European Society of Cardiology (ESC) Guidelines for primary prevention of sudden cardiac death? Can treatment of predominant (>50%) obstructive sleep apnea by appropriate Positive Airway Pressure (PAP) therapy decrease risk of sudden cardiac arrhythmic death in ICM patients? Can treatment of predominant (>50%) obstructive sleep apnea by appropriate PAP therapy improve cardiovascular outcomes in ICM patients indicated for ICD/CRT-D implant? Does obstructive sleep apnea represent a novel factor that may improve risk stratification of sudden cardiac death and advance identification of those patients that will benefit from ICD/CRT-D therapy?

Implantable Cardioverter Defibrillator (ICD) Support Groups and Veterans

Ventricular FibrillationVentricular Tachycardia1 more

In this study, we will compare the quality of life in veterans having ICD who attend the ICD support groups to those who do not. We ask them to answer a set of quality of life questionnaires at baseline and then at 3,6,9 and 12 month visits. These questionnaires would be analyzed to assess if attending support groups made a difference. These results will be compared to a similar study done at Emory University on non veterans.

Myocardial InfarctionHeart Failure1 more

The objective of the study is to demonstrate that in post-MI patients with symptomatic heart failure who receive optimal medical therapy for this condition, and with reduced LVEF ≤ 35% but low risk for SCD according to a personalised risk score, optimal medical therapy without ICD implantation (index group) is not inferior to optimal medical therapy with ICD implantation (control group) with respect to all-cause mortality.

Selection of Shock Energy in Out-Of-Hospital Cardiac Arrest

Sudden Cardiac DeathArrhythmia1 more

Sudden cardiac death is the most frequent cause of death in industrialized countries. The most efficient interventiont in ventricular fibrillation is defibrillation in an appropriate timely manner. But since the intervention of defibrillation the optimal shock energy is unknown. As a too low energy is not able to terminate ventricular fibrillation a too high energy may cause asystole wich jeopardizes survival itself. We study the efficacy of different shock energies on the termination of ventricular fibrillatiion and survival.

Subcutaneous ICD Therapy Combined With VT Ablation for the Secondary Prevention of Sudden Cardiac...

Sudden Cardiac Death

This study evaluates the feasibility and safety of a management approach that incorporates VT-ablation and S-ICD implantation in secondary prevention patients. This is a single arm prospective study with 30 patients eligible for implantation of an ICD for the secondary prevention of sudden cardiac death.

Sodium Bicarbonate in Cardiopulmonary Resuscitation

Sudden Cardiac Arrest

Out-of-hospital cardiac arrests (OHCA) account for over 60% of deaths from coronary artery disease. The annual incidence of OHCA treated by Emergency Medical Systems (EMS) is 41-89 per 100,000 population. Outcome of OHCA and cardiopulmonary resuscitation (CPR) is very poor: Less than 1/3 of the victims regain spontaneous circulation (ROSC), 40-60% of those achieving ROSC suffer significant neurological disability due to brain hypoxia and only 1.7-6.4% are discharged from the hospital. In order to minimize hypoxia time, the primary goal of CPR is to achieve return of spontaneous circulation (ROSC) as fast as possible. Metabolic (lactic) acidosis develops rapidly during CA and is considered detrimental to CPR outcome. Sodium bicarbonate (SB), a generic, commonly used acid buffer, was subjected only to a single, small, prospective controlled trial that found a trend towards improved outcome in prolonged OHCA and CPR. Another study indicated that EMS's that used SB early and often during CPR had significantly higher ROSC rates and better long-term outcome compared with EMS's that used SB more seldom and administered it late in the course of CPR. Aim of the Study: To determine whether early administration of SB during OHCA and CPR improves short-term CPR outcome.

DeathSudden4 more

To establish whether a pre-hospital advanced physician/ paramedic cardiac arrest team that is ECMO capable can establish ECMO flow within 30 minutes of collapse. The Sub30 study will investigate the technical and logistical feasibility of instituting pre-hospital Extracorporeal Cardiopulmonary Resuscitation (ECPR) within 30 minutes of collapse for selected patients (n=6) in a geographical sector of Greater London. It will achieve this through a unique collaboration between the primary emergency dispatch and response services (London Ambulance Service NHS Trust, LAS), pre-hospital practitioners (LAS and London Air Ambulance) and clinicians in ECMO (Barts Health NHS Trust).

Benefits of ICD for the Primary Prevention in Patients With Valvular Cardiomyopathy

Valvular Heart DiseaseImplantable Cardioverter Defibrillator2 more

The prevalence of valvular heart disease is on the rise along with the aging society and the generalization of echocardiography. Furthermore, the rheumatic valvular heart disease is much more prevalent in Asia than in Western countries, and the frequency of valve disease is higher in Asia. The effect of an implantable cardioverter defibrillator (ICD) in the primary prevention of sudden cardiac death in ischemic cardiomyopathy is well established and has become a standard of care. However, there is limited research on the effect of ICD implantation for primary prevention in patients with heart failure due to valvular heart disease. In a small study, the incidence of fatal cardiac arrhythmia was lower in patients with valvular cardiomyopathy (5%) who received ICD implantation for primary prevention than in those with ischemic cardiomyopathy. But there is also a report that the appropriate ICD treatment is not different from that of ischemic heart disease in valvular heart disease patients. Therefore, it is necessary to study the primary prevention effect of ICD on valvular cardiomyopathy in a larger number of patients. The purpose of this study was to investigate the effect of ICD on the prevention of sudden cardiac death in patients with heart failure due to valvular heart disease through prospective, multicenter, and observational studies.
