Active clinical trials for "Atrial Fibrillation"

The aim of this study is to assess whether prophylactic treatment with metoprolol or losartan is able to reduce the incidence of atrial fibrillation (AF) in patients undergoing thoracic surgery for lung cancer, showing elevated plasma levels in NT probrain natriuretic peptide (NT-proBNP), measured in the perioperative period.

The objective of this study is to investigate whether paracetamol, given at therapeutic doses (2g/day and 3 g/day), may potentiate the anticoagulant effect of warfarin.

The main purpose of this study is to provide dose-guiding information by assessing the safety and tolerability of 4 different dosing regimens of an extended-release (ER) formulation of AZD0837 compared with well-controlled, dose-adjusted Vitamin-K antagonists (VKA) (aiming for an international normalized ratio (INR) 2.0 to 3.0) in patients with non-valvular atrial fibrillation (AF) with one or more additional risk factors for stroke.

This study is designed to evaluate the safety, tolerability and preliminary efficacy of vernakalant (oral) in subjects with sustained atrial fibrillation of greater than 72 hours and less than 6 months duration

To assess the efficacy of dronedarone in preventing cardiovascular hospitalization or death from any cause in a population of high-risk patients with atrial fibrillation/atrial flutter (AF/AFL). To assess that dronedarone is well tolerated in this population.

The purpose of this study is to investigate the optimal daily dose and dose regimen of YM150 in subjects with non-valvular atrial fibrillation (NVAF), primarily based on safety and tolerability data.

The purpose of this study is to test whether Fondaparinux is effective and safe to prevent thromboembolic events (like for example strokes) and bleeding events in patients who undergo a normalisation of their heart rhythm disturbance. Fondaparinux will be compared with Heparin and tablets containing Vitamin-K-Antagonists (Phenprocoumon, Fluindione, or Warfarin).

The primary goal of this study is to assess the safety of Plexisyl-AF administered by direct application to the cardiac fat pads in patients undergoing coronary artery bypass grafting. Secondary goals of the study are to assess the potential response of Plexisyl-AF to reduce the occurrence of postoperative atrial fibrillation and assess the performance of the electrostimulator device to confirm the location of the epicardial fat pads (nerves). The occurrence of postoperative atrial fibrillation will be monitored by continuous cardiac monitoring.

To evaluate whether atrial fibrillation (AF) therapies in Guidant Pulsar Max II or Insignia Plus DR have an effect on the occurance of AF in patients with no prior history of AF

The purpose of this study is to determine if atorvastatin (Lipitor) reduces the occurence of abnormal heart rhythm (atrial arrhythmia) following non cardiac thoracic surgery.
