The Correlation Between Sleep Quality and Atrial Fibrillation Undergoing High-flow Nasal Cannula Oxygen (HFNC)

Atrial fibrillation (AF) has been reported to occur in up to 20-40% of patients undergoing coronary artery bypass grafting (CABG). Postoperative AF plays a major role in the determination of hemodynamic deterioration and can be associated with thromboembolic stroke. Aside from the risk factors of age, pain, cardiac dysfunction and ...


Impact of the Relaxation Response Resiliency Program on Patients With Atrial Fibrillation

Atrial fibrillation (AF) is a very common cardiovascular disease. Symptoms include dizziness, palpitations, lightheadedness, shortness of breath, fatigue and exercise intolerance. AF is also associated with a high risk of complications like thrombo-embolism and stroke, heart failure, dementia. The presence and severity of these symptoms and complications adversely affect a ...

Phase N/A

Detection of Silent Atrial Fibrillation aFter Ischemic StrOke

Atrial fibrillation (AF) is associated with a high risk of stroke and its prevalence increases in subjects aged 65 years. After an ischemic stroke, the use of standard monitoring methods may underestimate the detection rate of AF. Recent studies demonstrated a fourfold to sixfold increase in the detection of AF ...


Comparison Between Contact Force Guided and Blinded Strategy on PV Isolation in AF Patients

Sixty patients will be randomized to select right or left pulmonary veins whether to apply contact force-guided ablation or contact force-blinded ablation strategy. Each PV will be ablated with same contact force-sensing catheter (Thermocool Smart Touch Catheter, Biosense Webster Inc. CA). The PV (right or left) which will be randomized ...


Evaluation of the CIRCA Monitoring System in Prevention of Esophageal Lesions Following RFCA

Dr. Gregory Feld, M.D. is conducting a research study to find out more about the short-term effects on the esophagus of left atrial ablation (guided by Circa esophageal temperature monitoring system). The financial supporter of this study is Circa Scientific, LLC. When the investigators perform a radiofrequency catheter ablation (RFCA) ...

Phase N/A

Tissue Blood and Biomarkers to Predict Future Atrial Fibrillation

Study procedures: The left atrial appendage (LAA) will be removed for research and intended prophylactic purposes, using a surgical stapler or surgical knife prior to the standard procedure. Epicardial mappings may be performed during cardiac surgery with a 48-multi-electrode. Patients will be followed with regular 24-hour Holter investigations. This study ...

Phase N/A

Sleep Disordered Breathing in Patients With Paroxysmal Atrial Fibrillation

For the present project we have established a research team from 2 different university hospitals. This team, including high ranked, internationally renowned scientist from both clinical and basic sciences, will make a framework for PhD candidates and will ensure the patient cohort. Patients with paroxysmal AF and SA will be ...

Phase N/A

Circulating BDNF in Patients With Atrial Fibrillation Undergoing Catheter Ablation or Exercise Training

The main purpose of this project is to determine the impact of atrial fibrillation interventions (catheter ablation and exercise training) on circulating BDNF concentrations in patients with atrial fibrillation. It also seeks to determine if there is a relation between circulating BDNF concentrations and mental health (depression severity, quality of ...

Phase N/A

Internet-based Cognitive Behavior Therapy for Atrial Fibrillation

Atrial fibrillation (AF) is the most common cardiac arrhythmia (irregular heartbeat) affecting 3% of the population. AF is associated with poor quality of life (QoL) and large costs for society. In a considerable proportion of patients, AF symptoms (e.g., palpitations, fatigue, and chest pain) are not alleviated by current medical ...

Phase N/A

Botulinum Toxin Injection Into Epicardial Fat Pads to Prevent Atrial Fibrillation in Patients Undergoing Cardiac Surgery

The aim of this prospective randomized double-blind study was to compare the efficacy of botulinum toxin injection in epicardial fat pads for preventing recurrences (in early postoperative period) of atrial tachyarrhythmia in patients undergoing cardiac surgery.
