Filter by:The purpose of this study is to determine the feasibility and efficacy of the GAMification to Encourage End-Of-Life (GAME-EOL) intervention, which uses the Hello Game program to encourage and facilitate quality end-of-life (EOL) discussions between implantable cardioverter defibrillators (ICD) recipients and family members of ICD recipients.
Implantable cardioverter defibrillators (ICD) are used to treat life-threatening heart rhythm disturbances (arrhythmias). They have been proven to reduce the risk of sudden cardiac death; however, there are limitations with current ICDs. Firstly, they may deliver inappropriate therapies (therapies delivered in the absence of life-threatening arrhythmias). Secondly, slower life-threatening arrhythmias may be left untreated because current programming recommendations, designed to minimise inappropriate therapies, rely predominantly on heart rates. Therefore, there is considerable potential to make ICDs safer with more sophisticated ICD algorithms. In this research study the investigators will collect data from participants with newly implanted or existing ICDs whilst they are in induced or spontaneously occurring abnormal rhythms. The data will come from sensors placed on the skin that can measure blood flow or electrical properties of the body. In addition, in 20 participants, the investigators will also collect further data from a small loop recorder implanted under the skin. The investigators will use this data to help develop and validate new methods of reliably identifying life-threatening arrhythmias so that future ICDs deliver therapies when only needed. The research is funded by the British Heart Foundation, and will take place at Hammersmith Hospital over 3 years. The investigators aim to recruit 100 patients in total.
Shock testing during ICD generator replacement has been omitted by many centers. A previous study revealed lead failures in internally cardioverted patients with previously normal HV-lead values. The real prevalence of unrecognized "silent" lead failure in ICD patients remains unknown. As a consequence, patients may be equipped with an ICD which is unable to provide life-saving shocks. The proposed registry aims to include patients presenting for ICD generator replacement or electrical cardioversion of atrial arrhythmia. The protocol mandates either a commanded synchronized high energy shock prior to generator replacement or internal cardioversion of atrial arrhythmia to provoke the unmasking of silent lead failure.
Nowadays, Sudden Cardiac Death (SCD) due to malignant arrhythmias is an important cause of death among acute myocardial infarction (AMI) survivors. Preventive strategies with implantable cardioverter-defibrillators (ICD) are the best clinical option for patients, but associated sociosanitary impact in the National Health Systems and the fact that current implant strategy not always results in benefits for the patient requires to develop further selection criteria. The TeVeO project aims to study the events that take place early following an AMI to predict the short- and long-term risk of experiencing a potentially lethal ventricular tachycardia (VT). The project will carry out an observational and multicentric study involving 5 different hospitals to: a) qualitative and quantitative characterize non-sustained VTs (NSVT) that take place during the first 6 months after an AMI and b) characterize the evolution of the substrate (scar and surrounding tissue) in patients meeting criteria for ICD implant. Patients included in the study will be implanted with an implantable loop recorder (ILR) in order to register NSVT and cMRI images will be acquired prior to hospital discharge and at 6 months after AMI to study the substrate. Further patients' management will follow the protocols within each entity. Project results will allow us to stratify patients according to identified risks for developing malignant VT, which will improve patient selection for ICD implantation and will contribute to tailor patients' treatment and prevention, improving the cost-effectiveness of these devices and minimizing their associated problems and sociosanitary burden.
This study is a multi-center open-label randomized study, and we sought to investigate the redundancy of post-procedural prophylactic antibiotics in cardiac implantable electronic device implantation. There are 2 arms in this study. One arm will receive pre-procedural intravenous antibiotics only. The other arm will receive both pre-procedural intravenous antibiotics and post-procedural 3-day oral antibiotics.
This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.
The purpose of this registry is to prospectively assess outcomes of device-treated ventricular tachyarrhythmias and all-cause mortality in non-ischemic cardiomyopathy patients indicated for ICD or CRT-D implantation for the primary prevention of sudden cardiac death. Differences in outcomes will be evaluated by sex and by device type.

This study evaluates whether a rigorously controlled high-normal level of serum-potassium (4.5-5.0 mEq/L) using dietary recommendations, potassium supplements and mineralocorticoid receptor antagonists will results in a lower incidence of cardiac arrhythmias in patients with an ICD. Patients will be randomized to this treatment or a control arm, where patients will receive usual guideline recommended follow-up.
This is the first feasibility test of a highly portable home-based exercise intervention after an ICD, using technology monitoring (rather than self-report) of intervention progress and outcomes. Evidence for intervention effectiveness will inform algorithms for initiating exercise post-ICD more broadly in clinical practice. This study aligns directly with recent scientific statements that recommend testing behavioral interventions for ICD patients that are based on participant engagement, use cognitive behavioral approaches, and are readily available when most needed.
