Active clinical trials for "Atrial Fibrillation"

The main objectives in this study were to examine the cardiac structural and functional changes in patients with persistent and permanent AF, with the aim of improving our understanding of the underlying pathophysiological mechanisms. In addition we aimed to identify variables predictive of recurrent AF.

The purpose of this study is to evaluate the safety and feasibility of the IV loading strategy in patients who are selected to receive sotalol.

Atrial fibrillation (AF), a condition where the top chambers of the heart beat irregularly, is a major health problem. The long-term goal of this project is to use a personal, mobile heart monitor to help patients better recognize recurrent AF and improve patients' ability to better manage their condition. A total of 300 patients with a history of AF will be included in the study, with 150 patients receiving an iPhone with the mobile monitoring device and educational text messaging and the remaining 150 patients continuing with their regular medical care. Each patient will be included in the intervention period for 6 months. The rate of recurrent AF and treatments meant to manage AF and other heart conditions will be determined for both groups. Patients in both groups will complete a series of questionnaires at the start and end of the 6 month study period to look at differences in quality of life and knowledge of AF.

Atrial fibrillation (AF) is a major and rapidly growing cardiac disease characterized by irregular heart rhythm. Living with AF can lead to stress, anxiety and depression for both patients and their families with increased risk of lost working days, hospitalization, and worsening of the disease. However, family-focused nursing has shown to capture the family's feelings and this could change the negative circle into a positive circle. The study aim is to examine how families experience living with a family member with AF and if family involvement through a family focused nursing intervention and group education can improve quality of life for AF patients. Family unit interviews, a study with focus group interviews with family members, and a randomized fidelity study evaluating the effect of the family focused nursing intervention will provide evidence-based knowledge on how to implement family focused nursing into care of patients with AF.

The purpose of this study is to assess the effectiveness of a newly developed interdisciplinary nurse-coordinated AF expert program for primary care patients. Therefore a prospective, pragmatic clustered randomized controlled trial will be performed in general practices.

To ensure a successful percutaneous left atrial appendage (LAA) closure, it is important to select the correct size of the closure device used for each patient. To define and measure the size of the LAA, 2D transesophageal echocardiography (TEE) has been typically used. An increasing number of hospitals recently switched to measure the size of the LAA using a cardiac computed tomography (CT) scan. Although this CT scan helps to better define and measure the LAA, it is still difficult to determine the exact anticipated 'landing zone' or 'position' of the closure device. A novel strategy of preprocedural planning includes the use of preoperative computer simulations based on CT imaging (Feops HEARTguideTM), where the device is deployed with a computer simulation into the patient-specific LAA anatomy to provide the operator both optimal and suboptimal scenario's showing different sizes and positions of the closure device. The aim of this study is to assess whether use of FEops HEARTguide computer simulations based on cardiac CT-imaging can contribute to a better preprocedural planning and improved procedural outcomes of percutaneous LAA closure procedures with an Amplatzer Amulet device. The PREDICT-LAA trial will investigate the possible positive effect of a computer simulation using a CT scan of the LAA performed prior to the procedure. The hypothesis is that by using this new computer simulation, better planning of the intervention can be obtained.

A Randomized, Crossover Trial is conducted to Evaluate Consistency Atrial fibrillation diagnosis between the Wearable Dynamic ECG Recorder and the Control device. In this investigation, the following indicators is also evaluated: Sensitivity and specificity of the ECG App algorithm in detecting atrial fibrillation compared with physician-adjudicated Gold Standard ECG recorder. Waveform qualitative assessment Safety incident assessments. 114 subjects (60 healthy subjects in phase I and 54 subjects with atrial fibrillation diagnosis in phase II) are enrolled in the investigation according to the criteria.

The aim of the study is to test if patients under oral anticoagulation therapy who are going to participate in the education program will have better Health-related quality of life, higher rate in pharmacological treatment adherence and better self efficacy to manage the treatment.

The purpose of this study is to evaluate the effect of a cognitive behavior therapy distress management program targeting wellbeing in patients with atrial fibrillation and their relatives.

Recent advancements with implantable cardiac device technology include extensive diagnostic and therapeutic algorithms for prevention as well as termination of atrial tachyarrhythmias (ATA). Preventive atrial pacing (PAP) and a novel atrial antitachycardia pacing algorithm (Reactive ATP™) in conjunction with managed ventricular pacing (MVP) recently has been shown to reduce progression to permanent atrial fibrillation (AF) in pacemaker patients with intact atriovenous (AV) conduction and a history of ATA. Whether the use of Reactive ATP™ for reducing AF burden extends to patients with an implantable cardioverter defibrillator (ICD), who typically have structural heart disease and heart hailure (HF), is unknown.
