Active clinical trials for "Atrial Fibrillation"

The primary objective of this study is to demonstrate how dronedarone (Multaq®) may aid in the slowing of progression of left atrial and ventricular fibrosis in patients with atrial fibrillation as assessed by late gadolinium enhanced magnetic resonance imaging.

The trial seeks to determine if apixaban, an investigational anticoagulant (blood-thinner) is as effective as standard therapy (warfarin) in preventing stroke and systemic embolism in subjects with atrial fibrillation and risk factors for stroke.

Atrial fibrillation is an irregular heart rhythm which requires long term anticoagulation to prevent risk of stroke and long term poor outcomes. At the same time one have heart surgery, a small additional procedure can be done to treat atrial fibrillation. Surgeons have a choice of six different devices that he or she can use to treat your atrial fibrillation. It is not known at this point which device is best at treating you, as each device seems to have the same success rate at curing atrial fibrillation. One of the six devices will be selected randomly by card pulled out at the time of enrollment. It is therefore the purpose of this study to compare the devices to each other and to follow up after surgery to determine if any one device is best. This information will be valuable to surgeons and to patients as the treatment for atrial fibrillation develops in the future.

Atrial fibrillation (AF) is a very common arrhythmia causing many symptoms resulting in numerous hospitalizations. Catheter ablation is a technique that has evolved significantly to improve symptomatic recurrences, but does not offer a 100% cure rate. We hypothesize that the use of aggressive BP lowering will reduce the rate of recurrent AF after catheter ablation for AF. We plan a randomized clinical trial of aggressive BP lowering versus standard BP control to investigate this.

This study is to assess the safety of a potential new drug DU-176b for the prevention of stroke/systemic embolic event (SEE) in individuals with non-valvular atrial fibrillation (AF). The duration is 3 months of treatment and a 30 day follow-up visit.

This study will be conducted in male and female subjects aged 18 to 80 years, inclusive, with non-valvular AF and a CHADS2 Score of at least 1. Subjects will be treated on an outpatient basis. The subjects will be allocated randomly to the open-label warfarin or any double-blind DU-176b dosages. DU-176b will be administered orally for 12 weeks at two fixed doses. Warfarin will be used as active control. Warfarin dosing will be managed and monitored by the Investigator with the dose adjusted to achieve an INR of 2.0 to 3.0, inclusive. The primary endpoints are incidence of major, clinically relevant non-major and minor bleeding events (all bleeding).

The purpose of this study is to provide safety and tolerability data for AZD0837 during long-term treatment (5 years) in patients with non-valvular atrial fibrillation (AF) and one or more additional risk factors for stroke and systemic embolic events (moderate to high risk patients).

Atrial Fibrillation (AF) is a common postoperative complication of cardiac surgery, occuring in approximately 25-30% of coronary artery bypass graft (CABG) patients and 35-40% of heart valve repair/replacement patients. Efforts to decrease the high rates of AF have not made great inroads to the problem. The current standard of care is the use of preoperative and postoperative beta blockers. We propose to compare the use of prophylactic oral ascorbic acid with and without prophylactic oral amiodarone, in combination with oral beta blockers, for the prevention of atrial fibrillation after open heart surgery. The hypothesis is that either drug, or a combination of the two drugs, will be superior and safe when compared to beta blockers alone.

This study was a randomized, parallel group, open label trial using warfarin as comparator. Pharmacokinetics (PK) and pharmacodynamics (PD) were investigated only in BAY59-7939 groups (originally described in Japanese).

The purpose of this study is to determine the effect of statin therapy for prevention of atrial fibrillation (AF) in pacemaker and non-pacemaker patients with paroxysmal atrial fibrillation in the absence of significant coronary artery disease.
