Active clinical trials for "Atrial Fibrillation"

The purpose of this study is to understand temporal changes in clinical features and functions, and the relationship with outcomes of atrial fibrillation (AF). AF is a problem with speed or pattern that the heart beats. It is the most common type of arrythmia. The study will use data linkage of a single center patient data and national claims database in Korea. This study does not include an actual patient enrollment process.

This study aims to assess the relationship between body position and the occurrence of either atrial or ventricular premature beats and more complex arrhythmia

Patients with newly diagnosed pulmonary embolism and high thromboembolic risk will be randomized to screening for atrial fibrillation or standard of care using intermittent ECG registration for at least two weeks.

Researchers are trying to determine whether arterial stiffness detected by ultrasound can predict outcomes in the development and recurrence of atrial fibrillation.

Pulmonary vein isolation (PVI) using cryoballoon ablation is a well-established procedure for the treatment of atrial fibrillation (AF). However, the use of cryoballoon ablation in recent clinical trials have been limited to PVI. As such, patients with paroxysmal AF have been the main recipients of this procedure. In patients with persistent AF, or patients with paroxysmal AF and significant AF substrate other than the pulmonary veins, the utility of cryoballoon ablation is less straightforward. In such patients, the choices are to either use cryoballoon ablation in a PVI-only approach or alternatively, use cryoballoon ablation for PVI followed by the use of radiofrequency ablation for additional ablation and/or substrate modification. Substrate modification by targeting left atrial fibrosis detected on delayed enhancement magnetic resonance imaging (DE-MRI) is an increasingly popular approach with growing data showing its utility to decrease the risk of recurrence. The ability to use cryoballoon ablation for fibrosis based ablation in addition to PVI will therefore provide a significant advantage. This study will evaluate feasibility and the outcome of targeted ablation of left atrial fibrosis detected on DE-MRI in addition to pulmonary vein isolation using the Arctic Front Advance Cryoballoon Catheter.

The goal of this interventional study is to evaluate the risk of atrial fibrillation (AF) and other cardiac arrhythmias and diseases in breast cancer patients treated with radiation therapy (RT). In addition to regular follow-up of patients by the radiation oncologist for 5 years, cardiovascular screening at the end of follow-up, combining the use of a connected watch and a cardiological check-up, could make it possible to identify precisely the types and frequencies of these sometimes asymptomatic, and probably underestimated, cardiac diseases. The main questions it aims to answer are: To assess the incidence of AF and other cardiac arrhythmias and diseases occurring within 5 years after RT To evaluate absorbed doses in the heart and cardiac substructures (chambers, conduction nodes, coronaries, pulmonary veins) based on auto-segmentation models developped with deep learning algorithms To investigate whether the risk of AF and other cardiac arrhythmias and diseases is associated with cardiac irradiation characterized by these absorbed doses (dose-response relationship) Participants will be included between 2023 and 2025, 5 years after their RT: Retrospective data collection will be based on a medical questionnaire designed to identify cardiac pathologies present prior to RT and those having occured in the past, between RT and 5 years post-RT. Cross-sectional data collection will be based on screening for cardiac pathologies using a connected watch worn for 1 month (silent AF screening) and a cardiology consultation (including ECG and echocardiography) to identify cardiac pathologies at 5 years post-RT possibly not identified in the retrospective data collection.

To evaluate the progression of atrial myopathy through wearable devices and cardiac imaging.

The objective is to evaluate whether once weekly subcutaneous (SC) injection of idrabiotaparinux sodium (biotinylated idraparinux) is at least as efficient to prevent clots in brain and in the other organs than oral international normalized ratio (INR) adjusted-dose warfarin in patients with atrial fibrillation (AF).

Atrial fibrillation is a very common complication of pulmonary resection. Patients who develop atrial fibrillation require additional treatment and are more likely to stay in the hospital for longer period of time increasing the costs associated with the operation. We propose a randomized controlled trial to see if oral amiodarone given for one week before surgery can prevent atrial fibrillation after pulmonary resection. We plan to evaluate the incidence of atrial fibrillation in patients who received preoperative amiodarone and compare them to the incidence of atrial fibrillation in patients who did not received preoperative amiodarone.

The aim of the study is to show that an ambulatory ECG telemetry monitoring of some patients hospitalized for cerebral infarction increases the frequency of the diagnosis of atrial fibrillation, cause of their stroke, and reinforces the protection against recurrences.
