Active clinical trials for "Atrial Fibrillation"

The purpose of the study is to evaluate non-inferiority of oral anticoagulant (OAC) monotherapy to OAC plus single antiplatelet therapy (APT) in patients with atrial fibrillation (AF) and prior (>12 months) coronary stenting.

The purpose of this study is to investigate whether in patients with early persistent atrial fibrillation and mild to moderate early heart failure an aggressive upstream rhythm control approach, including aldosterone receptor antagonists and statins, dietary restrictions, counseling and cardiac rehabilitation programs, increases persistence of sinus rhythm compared with conventional rhythm control after one year of follow-up. A randomized long term extension of the RACE 3 will be performed with a total follow-up of 5 years to investigate the long term effects on persistence of sinus rhythm and cardiovascular morbidity and mortality of the two treatment strategies.

The purpose of this study is to compare the effectivity and safety of atrial fibrillation ablation, in comparison to antiarrhythmic drug therapy in patients with refractory, persistent atrial fibrillation.

This investigation is a prospective, nonrandomized multicenter clinical trial evaluating the outcome of patients with atrial fibrillation (AF) requiring concomitant open heart surgery plus the Cardioblate Surgical Ablation System using the modified Maze III procedure. The trial population includes patients requiring valve replacements or repairs, atrial septal defect (ASD) repairs, patent foramen ovale (PFO) closure or coronary artery bypass graft (CABG) procedures. The study objectives are to demonstrate that the Medtronic Cardioblate Surgical Ablation System can safely and effectively treat permanent AF patients.

The objective of this study is to compare the efficacy and safety of dronedarone to that of amiodarone for the treatment of patients with atrial fibrillation.

The purpose of this 7- to 13-month study is to determine the efficacy of 8 mg/day oral perindopril to prevent the recurrence of atrial fibrillation (AF) in patients with essential hypertension.

The investigators hypothesis is that in patients with permanent AF lenient rate control is not inferior to strict rate control in terms of cardiovascular mortality, morbidity, neurohormonal activation, NYHA class for heart failure, left ventricular function, left atrial size, quality of life and costs. Lenient rate control is defined as a resting heart rate <110 bpm.Strict rate control is defined as a mean resting heart rate < 80 beats per minute (bpm) and heart rate during minor exercise < 110 bpm. Patients will be seen after 1, 2, 3 months (for titration of rate control drugs) and thereafter yearly.

Individuals taking warfarin often need frequent dose changes as the international normalized ratio (INR) gets too high or too low which could result in a higher risk of thromboembolism, bleeding and early discontinuation of a highly useful therapy. This study will compare two approaches to warfarin dosing to examine the utility of using genetic information for warfarin dosing.

To evaluate the effects of K201 on sinus rhythm restoration, symptom score, various cardiovascular parameters, and safety.

This study is to evaluate acute and long-term safety and effectiveness of Left atrial appendage occlusion (LAA)with the AtriCure LAA Occlusion System. This device will be applied in patients with atrial fibrillation (AF), paroxysmal, persistent and permanent, undergoing cardiac surgery with a concomitant Maze/Ablation procedure.
