Active clinical trials for "Atrial Fibrillation"

The purpose of the ArcticLine Feasibility Study is to collect preliminary safety and effectiveness data on the ArcticLine Catheter.

This stepped wedge randomized intervention will apply machine learning algorithms in an electronic health record system to identify primary care patients with non-valvular atrial fibrillation (AF) who are at high risk of stroke and not on anticoagulation therapy. An Anticoagulant Management Service (AMS) will offer support to primary care providers regarding treatment for relevant patients (either warfarin and novel oral anticoagulants). This study seeks to: increase the proportion of appropriately anticoagulated patients with AF, understand the reasons for lack of anticoagulation, and document the proportion of patients with AF who are appropriately not anticoagulated (e.g. patient refusal, contraindication).

This study aims to evaluate the effects of a nurse-coordinated, empowerment-based integrated care model on self-care behaviors and psychosocial outcomes in patients with atrial fibrillation (AF), and to explore how this intervention affects the self-care behaviors and quality of life from the patients' perspective. Stroke prevention by oral anticoagulants (OAC) and control of arrhythmia and risk factors remain the cornerstones of AF management. However, under-prescription, non-adherence to treatment, and suboptimal anticoagulation control limit the efficacy of OACs. The poor abilities of patients regarding the self-control of arrhythmia and risk factors further contributes to worse outcomes. According to the World Health Organization, the best approach to chronic disease management involves the empowerment of patients to become active self-care agents. The literature indicates that a multifaceted, nurse-coordinated care model integrating all important care components with an empowerment approach could most effectively and actively engage patients in self-care. This mixed-methods study comprises a randomized controlled trial and an exploratory qualitative study. A total of 392 community-dwelling patients aged ≥65 years with a confirmed diagnosis of AF, a high stroke risk, and no OAC treatment will be recruited from the medical outpatient clinics of a university-affiliated teaching hospital. The patients will be randomly allocated to intervention or control groups, which will receive treatment via the nurse-coordinated integrated care model or standard care, respectively. We hypothesize that compared to patients receiving standard care, AF patients exposed to the nurse-coordinated care model will be more likely to achieve compatible patient and physician decisions regarding the use of OAC, as well as better changes in medication adherence, anxiety, depression and health-related quality of life both immediately and 6 months post intervention. This study will uniquely adopt an empowerment-based approach to equip patients as active agents in AF management through a nurse-coordinated integrated care model that comprehensively addresses their needs. The findings will advance our knowledge of patients' self-care behaviors in the context of AF and will provide a new model of care to improve health outcomes in this population.

This study examined patients on taking oral anticoagulants (OACs) are often prescribed for Atrial fibrillation (AFib) to determine the effectiveness of a multiple interactive health education program, which was developed based on the health belief model (HBM) and incorporated information technologies.

The purpose of this study is to validate an approach to decentralize, or virtualize, the clinical trial experience for enrolled subjects, through the coordinated use of multiple digital health and telehealth technologies. The study aims to validate the feasibility, acceptability and best practices of coordinating/integrating several individual digital health technologies to achieve execution of high compliance, cost-efficient, and scientifically sound clinical trials.

The purpose of the study is to assess the effects of BMS-914392 administration on the pharmacokinetics of a single-dose of metoprolol in healthy subjects.

The purpose of this study is to observe the performance of Therapy™ Cool Flex™ catheter by documenting the procedural parameters, major complications and recurrence of AF after ablation using Cool Flex ablation catheter for the treatment of paroxysmal atrial fibrillation. This study is an observational clinical study which is not based on any specific endpoints.

The purpose of this study is to quantify the accuracy of the atrial fibrillation diagnostics of the Reveal® XT in a clinical setting and to verify overall system performance, R-wave sensing performance, to obtain user feedback, from both patient and physician, and collect data on device safety.

The purpose of this study is to determine whether comprehensive post-hospitalization interdisciplinary care management can be an effective care delivery model to improve outcomes in low-income frail elderly.

The purpose of this study is to compare radiofrequency catheter ablation and antiarrhythmic drug treatment for the maintenance of sinus rhythm in paroxysmal atrial fibrillation patients.
