  • Amplatzer Amulet LAAO vs. NOAC

    open to eligible people ages 18 years and up

    The objective of this trial is to evaluate the safety and effectiveness of the Amulet LAA occluder compared to NOAC therapy in patients with non-valvular AF at increased risk for ischemic stroke and who are recommended for long-term NOAC therapy. The clinical investigation is a prospective, randomized, multicenter active control worldwide trial. Subjects will be randomized in a 1:1 ratio between the Amulet LAA occlusion device ("Device Group") and a commercially available NOAC medication ("Control Group"). The choice of NOAC in the Control Group will be left to study physician discretion.

  • Anticoagulation in ICH Survivors for Stroke Prevention and Recovery

    “Volunteer for research and contribute to discoveries that may improve health care for you, your family, and your community!”

    open to eligible people ages 18 years and up

    Primary Aim: To determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF). Secondary Aim: To determine if apixaban, compared with aspirin, results in better functional outcomes as measured by the modified Rankin Scale.

  • Does Eliminating Coffee Avoid Fibrillation?

    open to eligible people ages 21 years and up

    Given both the increasing population impact of atrial fibrillation (AF) and the widespread consumption of coffee in society, determining an associated benefit or risk of coffee consumption on AF is of great clinical relevance. This pilot study will evaluate the effect of randomly assigning participants undergoing electrical cardioversion to coffee abstinence or coffee consumption over a 6 month period. This pilot study will provide the first, randomized evaluation of coffee on AF outcomes and will provide important information on whether or not coffee has any effect on AF recurrence.

  • Transcutaneous (Tragus) Vagal Nerve Stimulation for Post-op Afib

    open to eligible people ages 18-80

    Patients undergoing cardiac surgery are at high risk of developing atrial fibrillation (AF), with estimated rates of 30-50% and occurs at approximately 2-4 days after surgery. The autonomic nervous system is known to play a key role in AF. Animal studies have indicated that duration and inducibility of AF can be decreased with intermittent vagus nerve stimulation (VNS). In humans, literature suggests that transcutaneous (tragus) VNS (tVNS) can serve as a potentially non-invasive therapy for treatment of post-operative AF (POAF) by reducing inflammation and increasing atrial refractory period. The purpose of this study is to determine the value of tVNS in reducing the burden of POAF and days of hospitalization after cardiac surgery.

  • Volunteers to Investigate Best Results for Ablation and Novel Therapies for Atrial Fibrillation

    open to eligible people ages 18 years and up

    VIBRANT-AF seeks to: - Identify clinically relevant predictors of effectiveness and complications of AF ablation procedures in a prospective, US-based, multi-center, real-world longitudinal study - Assess changes in modifiable lifestyle-related exposures influence the effectiveness of AF ablation - Determine incidence and predictors of complications of AF ablation procedures Participants will connect with the Eureka Research Platform and answer a series of surveys and activities over a one-year period. They will be asked about lifestyle habits, recurrence of AFib, hospitalizations, and general feelings and emotions.

  • Early Dronedarone Versus Usual Care to Improve Outcomes in Persons With Newly Diagnosed Atrial Fibrillation

    Sorry, in progress, not accepting new patients

    While there are several completed clinical trials that address treatment strategy in patients with symptomatic and recurrent AF, there are no randomized clinical trials that address treatment for first-detected AF. In usual care, these patients are started on an atrioventricular nodal blocking agent (beta-blocker or non-dihydropyridine calcium channel blocker) along with stroke prevention therapy. The investigators hypothesize that earlier administration of a well-tolerated antiarrhythmic drug proven to reduce hospitalization may result in improved cardiovascular outcomes and quality of life in patients first-detected AF. The purpose of this study is to determine if treatment with dronedarone on top of usual care is superior to usual care alone for the prevention of cardiovascular hospitalization or death from any cause in patients hospitalized with first-detected AF. All patients will be treated with guideline-recommended stroke prevention therapy according to the CHA2DS2-VASc score. The treatment follow-up period will be 12 months. There will be two follow-up visits. Consistent with the pragmatic nature of the trial, the first follow-up will occur between 3 -9 months and the 2nd will occur at 12 months (with a window of +/- 30 days). Approximately 3000 patients will be enrolled and randomly assigned (1:1) to study intervention. The study intervention will be dronedarone 400 mg twice daily in addition to usual care versus usual care alone.

  • Semaglutide to Reduce Atrial Fibrillation Burden

    Sorry, currently not accepting new patients, but might later

    Atrial fibrillation (AF) is the most common arrhythmia worldwide. AF is associated with obesity and the co-morbidities of obesity, including hypertension and obstructive sleep apnea (OSA) which increase left atrial (LA) size and decrease LA function. Semaglutide, a Glucagon-like peptide receptor 1 agonist (GLP-1 RA), is currently approved by the Food and Drug Administration for weight loss for individuals with and without diabetes. The effects of pharmacologic weight loss with Semaglutide on AF are unknown. The investigators plan on conducting a randomized controlled trial of semaglutide versus placebo in individuals with paroxysmal or early persistent AF (>10% AF burden on ambulatory monitoring, a previous electrical cardioversion, or AF lasting ≥ 7 days but < 3 months who have a body mass index ≥ 27.0 kg/m2. The trial will last for 52 weeks. The primary outcome will be the change in AF burden for 2 weeks, immediately before starting the medication or placebo to two weeks starting at week 50, as determined by an implantable loop recorder or two week ambulatory Additional outcomes will be change in epicardial adipose tissue as determined by chest/abdomen/pelvis computed tomography scan at enrollment and at week 52, change in apnea-hypopnea index from baseline sleep study to week 52 sleep study, change in LA longitudinal strain from baseline echocardiogram to echocardiogram at 52 weeks, and change on symptom surveys.

  • Thiamine Intervention and Coronary Artery Bypass Grafting

    Sorry, not yet accepting patients

    The purpose of this study is to gain a better understanding of the association between brain changes and cognitive deficits in coronary heart disease (CHD) patients undergoing coronary artery bypass grafting (CABG) and whether a low-cost thiamine intervention can be used to reduce post-CABG cognitive issues in CHD subjects.

  • Health eHeart BEAT-AFib - Health eHeart Biomarkers of Early Atrial Transformation in Atrial Fibrillation

    Sorry, accepting new patients by invitation only

    Atrial fibrillation (also known as AFib or AF) is the most common abnormal heart rhythm and results in an irregular beating of the heart. Currently, there is no way of identifying patients at most risk for the development or progression of AFib or those that will best respond to treatment. The purpose of this study is to improve our understanding of AFib and to find new ways of identifying those patients most at risk for developing AFib, have progressive AFib or be less responsive to treatment. For this reason, the investigators are studying imaging, blood, and digital markers that may contribute to AFib Subjects will receive mobile devices (uch as an AliveCor Kardia and a VivaLnk Wearable ECG patch or similar devices) for remote electrocardiographic (ECG) monitoring. Additionally, subjects will use features using a smartphone research app (on the Eureka Research Platform) to monitor other important things such as activity, sleep, heart rate and others as they are developed. All subjects will receive serial blood draws and saliva sample collections once a year. Subjects will also undergo annual imaging in the form of an echocardiogram (Echo). Evaluations will be taken at baseline and once a year for three years from the baseline visit. Additionally, electronic surveys will be administered periodically (eVisits occurring every 3-6 months) using the mobile app.
