Filter by:This is a global retrospective and prospective, multicenter, observational patient registry to record outcomes from patients undergoing ablations for the treatment of Atrial Fibrillation.
This study was designed to compare the effects on atrial rhythm control between SGLT2 inhibitor and other oral hypoglycemic agents in patients with atrial fibrillation and diabetes mellitus. We are to compare efficacy and safety between these two groups.
Monocentric, prospective, randomized trial of cardiac surgical arrhythmia using endocardial radiofrequency atrial ablation compared with a cryo ablation system in the setting of cardiac surgery.
AF is the most common sustained arrhythmia in adults and its prevalence increases with advancing age. In this study, we aim to determine whether the published genome-wide polygenic scores for atrial fibrillation (GPSAF) can facilitate AF screening by accurately discriminating between patients with low and high risk for AF. All included patients are participating in the MHI biobank, an ongoing funded institutional DNA bank and clinical registry approved by the research ethics board where included patients consent for future genetic research. The study will compare AF detection rate using a 3 months near continuous monitoring in individuals with a high GPSAF with matched individuals from the bottom GPSAF.
The purpose of this study is to assess pharmacokinetics and pharmacodynamics of Apixaban and clinical outcome of Apixaban in Thai patients with nonvalvular atrial fibrillation with varying degree of creatinine clearance
To characterize the relationship between panic attack symptoms and atrial fibrillation episodes using a real-time assessment data capturing system that reduces recall biases of previous research.
Compare the difference of cognitive function between different treatment strategy in patients with persistent atrial fibrillation
To test the impacts of different exercise training programs to the cardiopulmonary function, muscle metabolism, and body mass composition
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.
Atrial fibrillation (AF) is one of the most common tachyarrhythmias with substantial morbidity, disability and mortality. It is estimated that the number of patients with AF is expected to reach 7 million by 2050. Radiofrequency catheter ablation (RFCA) are the effective treatment for patients with drug-refractory symptomatic paroxysmal or persistent AF. However, the successful rate of RFCA for persistent AF during the first procedure still relatively low, the investigators also need pharmacological cardioversion or external electrical conversion. Several studies showed intravenous nifekalant injection after RFCA provided relative high rate of sinus conversion during catheter ablation in paroxysmal or persistent AF. Nevertheless, there is still no acceptable universal opinion on which dosage of nifekalant is preferable for converting AF during the operation. In order to address this issue, the investigators initiated the study to evaluate the efficacy and safety of different doses of intravenous nifekalant injection in the rapid cardioversion of persistent AF during radiofrequency catheter ablation.
