Active clinical trials for "Atrial Fibrillation"

The need for new models of integrated care that can improve the efficiency of healthcare and reduce the costs are key priorities for health systems across the United States. Treatment costs for patients with at least one chronic medical or cardiovascular condition make up over 4-trillion dollars in spending on healthcare, with estimations of a population prevalence of 100-million affected individuals within the next decade. Therefore, the management of chronic conditions requires innovative and new implementation methods that improve outcomes, reduce costs, and increase healthcare efficiencies. Digital health, the use of mobile computing and communication technologies as an integral new models of care is seen as one potential solution. Despite the potential applications, there is limited data to support that new technologies improve healthcare outcomes. To do so requires; 1) robust methods to determine the impact of new technologies on healthcare outcomes and costs; and 2) evaluative mechanisms for how new devices are integrated into patient care. In this regard, the proposed clinical trial aims to advance the investigator's knowledge and to demonstrate the pragmatic utilization of new technologies within a learning healthcare system providing services to high-risk patient populations.

The current study will evaluate the potential of stimulating the R.auricularis of the vagus nerve located at the Fossa triangularis to ameliorate or suppress AF in the study Population!

An anticoagulation therapy is a critical treatment to prevent thromboembolism in non-valvular AF (NVAF) patients. Warfarin, a vitamin K antagonist, is the first oral anticoagulant approved for the treatment for prevention of thromboembolism and it had long been the only oral anticoagulant until the first non-vitamin K antagonist oral anticoagulants (NOACs). However, its safety and effectiveness remains unknown in real-world clinical practice in Japan

Red cell distribution width variations are increased in a variety of medical conditions such as congestive heart failure, acute myocardial infarction, pulmonary embolism, pneumonia, critical illness, and cardiac arrest , and is a predictor of mortality in the general population..

Atrial Fibrillation (AF) is the most common cardiac arrhythmia and the main cause of cardioembolic stroke. Oral Anticoagulation (OAC) has been shown to significantly prevent AF-related thromboembolism, however, despite convincing evidences and current guidelines recommendations, OAC tends to be underused in clinical practice especially in the oldest. Education and training to appropriately select people suitable for OAC for stroke prevention could be pivotal in the decision making process. According to the study project, physicians working in Internal Medicine and Geriatric wards, where are mainly admitted elderly people with AF, will undergo to a program of e-learning through computer-based simulation method reproducing clinical scenarios of patients aged 65 years or older, with known or newly diagnosed AF, admitted to hospital for any medical reason and requesting that a decision about long-term antithrombotic therapy is taken. Primary objective of the study is to investigate whether such educational intervention will improve the appropriate use and prescription rate of OAC in hospitalised elderly patients with AF, multimorbidity and polypharmacy, in comparison to the usual practice. The study will be a cluster randomised controlled trial involving a network of Internal Medicine and Geriatrics wards. Thirty-two wards will be recruited based on voluntary participation and randomised to receive an educational intervention through computer-based simulation, (N=16) or to continue with the usual practice (N=16). Subjects receiving the intervention will be all the staff physicians of the wards randomised in the intervention arm. The impact of the intervention compared with the usual practice will be evaluated in patients aged 65 years or older admitted to the participating centres with a known diagnosis of AF or newly diagnosed with AF during the hospitalisation.

Study name:A randomized clinical trial on atrial fibrillation screening by using an automated electrocardiogram system in an elderly Chinese population Rationale: Failure in the diagnosis and management of atrial fibrillation leads to high incidence of stroke and high mortality and disability. It is therefore imperative to diagnose and manage atrial fibrillation in a timely and effective fashion to prevent the complications of atrial fibrillation. Objective:The primary objective is to investigate whether more frequent ECG recordings and analyses with this automated ECG system (4 times/year) would significantly improve the detection of atrial fibrillation compared to a single annual ECG screen.The secondary objective is to explore whether even more frequent ECG recordings and analyses (8 times/year) would further improve the detection of atrial fibrillation. Study design: The present study is designed as a randomized controlled trial of parallel group (two). Study population: Men and women aged at least 65 years (n=7000) meet the inclusion/exclusion criteria. Randomization and treatment: Eligible subjects will be randomized in a 1:1 ratio into the usual and intensive screening groups with 3500 patients in each group, and within the intensive screening group in a 3:1 ratio into the intensive and more intensive subgroups with 2625 and 875 patients, respectively. Follow up: 1)Usual screening group: ECG recordings at baseline plus at 1 and 2 year of follow-up; three ECG recordings in total. 2)Intensive screening subgroup: ECG recordings at baseline plus quarterly during follow-up, at months 3, 6, 9, 12, 15, 18, 21 and 24; 9 ECG recordings in total. 3)More intensive screening subgroup: ECG recordings at baseline plus weekly during the first month of follow-up and quarterly afterwards, at weeks 1, 2, 3 and 4 and months 3, 6, 9, 12, 15, 18, 21 and 24; 13 ECG recordings in total. Sample size estimation: The number of required subject for the whole trial is 7000. Timeline: Start of subjects enrollment : December 2016; End of subjects enrollment : June 2017; End of study : October 2020 Organization: The Centre for Epidemiological Studies and Clinical Trials, Ruijin Hospital, Shanghai, China.

The purpose of the study is to investigate the impact of motivational interviewing in the adherence of patients with AF to oral anticoagulation (OAC) regimens. Patients assigned to the intervention group will be interviewed and guided on the importance of adherence to OAC medication, and will be contacted at 1 week, 2 months, 6 months and 1 year after discharge for educational interactive sessions. Patients in the control group will receive usual treatment and will be contacted at 1 year after discharge.

AF is associated with significant social and medical costs, including diminished quality of life (QOL) and increased health care utilization (HCU). This pilot study will enroll 200 adults with prevalent, non-valvular AF of ≤3 year's duration at University of Pittsburgh Medical Center (UPMC). The primary objective at present is to obtain extensive feasibility and pilot data in implementing the Embodied Conversational Agent (ECA) in concert with the Kardia (KAC) heart rhythm monitor.

This observational study evaluates peri-procedural results of the Niobe™ Remote Magnetic Navigation (RMN) ES system using the contact detection system (CDS) in patients undergoing standard of care radiofrequency ablation of cardiac arrhythmias. The objective of this observational study is to confirm system performance of the CDS and that it does not alter pacing, electrocardiograms, or mapping during RF ablation procedures.

This study intends to explore a new therapy to reduce the incidence of atrial fibrillation in thoracic patient who receive video-assisted thoracoscopic lobectomy .The results of the study are to assess the effects of this new intervention on the incidence，duration of atrial fibrillation and other complications including postoperative delirium after video-assisted thoracoscopic lobectomy .And reducing the burden of POAF on patients and their families, hospitals and public resources.
