Filter by:BACKGROUND AND RATIONALE Two out of three Americans are overweight and obesity is associated with hypertension, sleep apnea, atrial fibrillation. Metabolic syndrome with centripetal obesity is also a precursor to insulin resistance and the development of Type II diabetes mellitus. While multiple strategies for weight reduction are often recommended in physician visits, calculating calories and energy expenditure is often inconvenient and does not promote compliance. Intermittent fasting, or time-restricted eating, is a methods to limit caloric intake by fasting for 16 hours to promote ketosis and suppress insulin secretion. Weight loss and reduction in body fat has been observed with brief periods of intervention as time-restricted eating results in reduction in overall caloric intake. Prospective feasibility studies and randomized comparative trials with intermittent fasting are lacking. The investigators recommend caloric restriction in all of our patients that suffer from arrhythmias and BMI >30. However, they have not systematically measured compliance and the efficacy of lifestyle interventions. Lifestyle counseling and weight loss has been shown to decrease the progression and burden of symptomatic atrial fibrillation. Intermittent fasting can result in consistent reductions in body fat and weight without specific lifestyle counseling. The aim of the present observation cohort study is to assess the feasibility of recommending intermittent fasting in an arrhythmia clinic with regard to compliance and efficacy. The investigators hypothesize that compliance and adherence to a 16/8 intermittent fasting regimen will be >25% and result in weight loss, compared to the 6 month trend prior to the intervention. This pilot study will serve as the basis to power the first randomized trial comparing intermittent fasting with other types of dietary counseling for arrhythmia outcomes. OBJECTIVES To prospectively assess compliance to prescribed intermittent fasting, measured by adherence and change in weight at 6 months.
Left atrial catheter ablation including pulmonary vein isolation is a standard therapy in the management of symptomatic atrial fibrillation; however thermal esophageal injury is a known potential consequence of this procedure. Delivery of radiofrequency (RF) energy necessary to perform left atrial ablation has the potential to cause injury to the nearby esophagus including ulceration, hematoma, spasm, esophageal motility disorders, and, in the most extreme case, atrial-esophageal fistula.Esophageal mucosal lesions are the likely precursor to AEF, and esophageal mucosal lesions have been detected on post-ablation endoscopy after pulmonary vein isolation with an incidence ranging from 3% to 60%. Active esophageal cooling during RF ablation as a means of esophageal injury prevention has been investigated through mathematical models, pre-clinical studies, and in clinical trials. Existing data support the efficacy of this approach, but the practice has not been widely adopted due to lack of a commercially available device. The aim of this study is to evaluate the impact on procedural efficiency of ablation procedures performed using esophageal heat transfer to warm the esophagus during left atrial cryoablation.
This study examines the implications of providing remote physician care to home hospitalized patients compared to usual home hospital care with in-person/in-home physician visits.
The purpose of this pilot study is to determine if esophageal warming using the Attune Medical Esophageal Heat Transfer Device (EnsoETM) limits the frequency or severity of thermal injury during cryoballoon ablation of atrial fibrillation.
Atrial fibrillation (AF) is a highly prevalent, morbid condition. Anticoagulation to prevent thromboembolic strokes is a foremost priority in AF but adherence is challenging for patients and lapses in anticoagulation are common. Chronic disease self-management (CDSM) is a recognized program to enhance self-efficacy and improve adherence, quality of life, and patient-centered health outcomes. Rural patients with AF experience increased vulnerability to adverse outcomes due to geographic and social isolation, poor health care access, and limited health literacy. This study uses an innovative, scalable CDSM intervention to improve anticoagulation adherence in rural patients with AF.
Atrial fibrillation (AF) is a common, morbid condition with increasing prevalence. Poor health-related quality of life is common in AF. Patients experience debilitating symptoms and challenging adherence to long-term (possibly lifelong) anticoagulation. The increased risks of stroke, heart failure and mortality associated with AF persist even with optimal treatment. Morbidity in AF is further exacerbated by social factors. Limited health literacy carries challenges of learning a specialized terminology and navigating specialized treatments. In multiple cardiovascular diseases, self-care has demonstrated improvement in self-efficacy, health-related quality of life, symptom burden, and health care utilization - essential components of patient success with AF. Selfcare can provide the critical skills to navigate a challenging chronic disease and improve patient-centered outcomes. Delivery of self-care as a mobile health intervention can complement standard care with a longitudinal intervention to improve patient-centered strategies for AF. While self-care interventions for AF have focused foremost on self-monitoring of anticoagulation,self-care has demonstrated its potential to meet the "triple aim" of improved patient experience, reduced health care utilization, and lower costs.
This is a prospective, non-randomized study to refine the Study Watch's algorithm for AF detection within both persistent and paroxysmal AF subjects. The study will also collect data from an FDA-cleared wearable ECG sensor.
Given the risks associated with direct oral anticoagulants (DOACs) and the lack of defined pathways for patients prescribed this class of medications, the study intervention has the potential for an enormous impact in preventing medication errors and improving the quality of care transition, patient knowledge, and adherence with DOAC therapy.
Atrial fibrillation (AF) is one of the most common heart rhythm disorders and it is associated with a variety of symptoms leading to a considerable deterioration in quality of life. The Mental-AF trial is intended to inquire if an app-based mental training can reduce the occurrence of symptomatic AF episodes within the blanking period, i.e. the first three months after catheter ablation for AF.
