Continuous Data Collection and Analysis for Stroke Prevention Using a Wearable Sensor
Atrial FibrillationThe purpose of this study is to determine whether a wristband that detects your pulse can detect your heart rate and rhythm similar to electrocardiograms (ECG).
Post-operative Corticosteroid Treatment After Mitral Valve Surgery
Atrial FibrillationThe aim of the study is to intestigate whether three days intravenous corticosteroid management prevent atrial fibrillations in adults after mitral valve surgery. Prospective double-blinded randmized international multicenter study.
Data Collection Atrial Fibrillation Exploratory Study
Atrial FibrillationAtrial FlutterTo characterize the impact of Atrial fibrillation (AFib) and Atrial Flutter (AFl) on signals measured using a wearable cardiac monitor prototype device. To evaluate the relationship of AFib/AFl symptom severity with various physiologic signals measured from the wearable cardiac monitor prototype device.
PLUG Dementia Trial and MRI PLUG Dementia Sub-Study
Atrial FibrillationDementia1 morePLUG Dementia Trial: Patients will be screened at Intermountain Medical Center and at Intermountain affiliated anticoagulation clinics in the Salt Lake City region. Patients with atrial fibrillation that undergo a standard of care, clinically approved, left atrial appendage closure will be considered for study. All patients will be followed for 24 months, and will be assessed at the 3-, 6-, 12-, 18- and 24-months post-left atrial appendage closure as well as other visits deemed necessary for clinical care. All subjects will undergo protocol-specified laboratory tests and will complete 6 standard, validated questionnaires at each follow-up visit, except at the 3-month visit when only one questionnaire will be administered. A subset of patients (n=20), will receive a cranial MRI at baseline and 24-month visit. MRI PLUG Dementia Sub-Study: In addition to the above, 20 of the 60 subjects who are selected for participation in this sub-study will receive a cranial MRI at baseline and at the 2-year (24 months) follow-up visit.
Evaluation of a Non-Invasive Electrocardiogram-Assisted Blood Pressure Monitor
HypertensionAtrial Fibrillation3 moreApproximately one billion people suffer from hypertension worldwide. At least 10% of this population, that is, 100 million people, also suffers from associated chronic conditions namely, atrial fibrillation (AF), obesity, arterial stiffness (AS), and heart failure (HF). Personal interaction with medical practitioners (doctors) and review of published clinical research confirms that current non-invasive automatic blood pressure (BP) monitors that rely on BP pulse analysis alone cannot provide accurate measurement due to the unpredictable/weak nature of BP pulses in the above-mentioned chronic conditions. Lack of accuracy in BP estimation can lead to wrong diagnoses and hence to complications such as stokes and heart attacks. The Sponsor is developing a novel non-invasive BP monitor that is similar to existing automatic monitors yet is capable of acquiring and analyzing electrocardiogram (ECG) data in conjunction with BP pulse data to provide better and more accurate measurements in the above chronic conditions. The objective of this clinical trial is to evaluate the performance of this ECG-assisted BP monitor against invasive BP measurements in a small group of patients who suffer from the above conditions.
Clinical Value of Left Atrial Appendage Flow for Prediction of Successful Catheter Ablation for...
Persistent Atrial FibrillationCatheter AblationThe purpose of this study was to determine whether left atrial appendage flow velocity, as determined using trans esophageal echocardiography (TEE), predicts the outcome after catheter ablation of persistent Atrial fibrillation( pAF).
AVJ Ablation Followed by Resynchronization Therapy in Patients With CHF and AF
Atrial FibrillationCongestive Heart FailureThe purpose of the study is to determine if the combination of AVJ ablation followed by BiV pacing significantly improves functional status and exercise capacity compared to pharmacologic rate control in patients with chronic AF and depressed ejection fraction, regardless of rate or QRS duration.
A Nationwide Observational Study Looking at Effectiveness and Bleeding Complications of NOACs vs....
Non-valvular Atrial FibrillationUsing mandatory nationwide registries and possibly hospital electronic medical records in Norway, the researchers want to understand how well a group of drugs called "non-vitamin K antagonist oral anticoagulants" (rivaroxaban - Xarelto; apixaban - Eliquis; dabigatran - Pradaxa) works in patients with non-valvular atrial fibrillation (this is a condition when the heart beats irregularly) compared to another older drug, a vitamin K antagonist oral anticoagulants (warfarin) and how safe these drugs are. The primary objective of the study is to assess the occurence of an ischemic stroke (a condition when an artery that brings blood to the brain is blocked) and intracranial hemorrhage (a serious condition when a diseased blood vessel within the brain bursts).
Atrial Fibrillation Associated With Heart Failure Treated by BIOTRONIK's CRT-DX System
Heart FailureAtrial Fibrillation1 moreThe purpose of the BIO-AffectDX Study is to prospectively evaluate improvement from baseline in heart failure subjects with atrial fibrillation (AF) implanted with a two-lead CRT-DX system, with emphasis on a comparison of patient outcomes between AF subtypes.
Cardiac Monitoring of Post-Operative Cancer Patients Experiencing Atrial Fibrillation
Post-Operative Cancer Patients Experiencing AtrialFibrillationThe purpose of this study is to assess whether it is possible and acceptable to monitor patients at a distance who experience a condition called atrial fibrillation after their cancer surgery. Some patients have no other clinical reason for staying in the hospital after cancer surgery except in order to control their heart rhythm. Being able to send these patients home earlier and monitor them at a distance from their home can be good for their quick recovery. Studies have shown greater quality of life and patient satisfaction when patients are monitored at a distance for conditions like atrial fibrillation, however cancer patients have not been studied.
