Paroxysmal Atrial FibrillationPersistent Atrial FibrillationThis prospective, multicenter observational study will examine the ability of model based fast anatomical mapping (mFAM) to create left atrial (LA) geometry for atrial fibrillation ablation.
Health eHeart BEAT-AFib - Health eHeart Biomarkers of Early Atrial Transformation in Atrial Fibrillation...
Atrial FibrillationAtrial 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.
Necessity of Anti-Arrhythmic Medication After Surgical Ablation for Atrial Fibrillation
Atrial FibrillationThe purpose of this study is to determine whether anti arrhythmic medication, specifically Amiodarone, is required during the first three months post surgical ablation. Hypothesis: Amiodarone will not be required during the first three months as verified by no increase in rehospitalizations for recurrent Atrial Fibrillation, and report of sinus rhythm at surgical follow up (approximately 3 weeks from date of surgery), 6 weeks and 12 weeks to include patients' first follow up with cardiologist at approximately 3 months post surgery.
Suppression Of Atrial Fibrillation With Ranolazine After Cardiac Surgery
Heart; Dysfunction PostoperativeCardiac SurgeryThe objective of this study is to show that ranolazine is a safe, viable and potent alternative for post-operative atrial fibrillation suppression in patients undergoing cardiac surgery
Prediction and Maintenance of Sinus Rhythm Among Atrial Fibrillation Patients
Atrial FibrillationAtrial fibrillation (AF) is the most common heart rhythm disorder seen in clinical practice, with an estimated 2.7-6.1 million people in the U.S. affected by the disorder [1]. Previous studies have demonstrated that left atrial volume is a predictive measure of incident atrial fibrillation [2]. This study aims to add to the literature by investigating predictive measures of left atrial global longitudinal strain (LA GLS) that would be suggestive of maintenance of normal sinus rhythm post cardioversion. If the investigators could gain insight on the connection between LA GLS and cardioversion among patients with atrial fibrillation, the investigators could potentially help the clinical management of patients pre/post cardioversion, and potentially change poor outcomes.
A Clinical Trial to Evaluate the Detection of Atrial Fibrillation for an One Day Versus More Than...
Atrial Fibrillation/Flutter in Patients With High Risk of StrokeThe purpose of this study is to evaluate the benefits in the atrial fibrillation detection rate of the continuous ECG monitoring group for more than 8 days by contrasting with one-day ECG monitoring using MEMO Patch PLUS in 1000 patients with atrial fibrillation-related symptoms in the high risk group of stroke. The participant is allocated randomly to One-day ECG monitoring group or the continuous ECG monitoring group for more than 8 days in ratio of 1:1, only if the participant provides informed consent and eligible for all the inclusion/exclusion criteria. The investigator confirms the results of MEMO Patch PLUS monitoring at 1 month from the date of MEMO Patch PLUS attachment. The participation of the subject is terminated on the 1 year from the date of MEMO Patch PLUS attachment. On that day, investigator evaluates incidence of the event associated with atrial fibrillation, the event is included ischemic stroke/transient ischemic accident, hemorrhagic stroke, systemic embolism, etc.
Reving Early Diagnosis of Cardiovascular Disease in the Utrecht Health Project
Coronary Artery DiseaseAtrial Fibrillation1 moreThe goal of this randomized trial is to compare the diagnostic yield of a screen-like early diagnosis strategy to usual primary care to detect coronary artery disease (CAD), atrial fibrillation (AF) and heart failure (HF) in community people aged 50-80 years who participate in the Utrecht Health Project. The diagnosis strategy consists of a questionnaire with questions related to symptoms suggestive of CAD, AF or HF, a focused physical examination, laboratory testing, electrocardiography, and echocardiography.

Registry of Cardiovascular Disease Patients
Ischemic Heart DiseaseCongestive Heart Failure4 moreA computerized registry of cardiovascular disease patients in a large health maintenance organization in Israel. The registry is aimed to be used by health professionals to identify cardiovascular disease patients and to follow the courses of their illnesses and risk factors.
Homeopathy for Prevention of Atrial Fibrillation After Aortocoronary Bypass Surgery
Atrial FibrillationAfter heart surgery, about 30% of patients suffer from atrial fibrillation. Patients are randomized into two groups receiving either potentized Strychnos Nux vomica or placebo under double blind conditions. Postoperatively, ECGs are done to monitor cardiac rhythm.
