The Effect of Reduced Dose of Enoxaparin on the Outcomes of Treatment With Enoxaparin

Patients treated with enoxaparin will be followed, sociodemographic , clinical and laboratory data will be collected. Clinical efficacy as well as adverse events will be monitored.

Phase N/A

Atrial Fibrillation and the Risk for Neurological Complications

B8: Atrial fibrillation and the risk of neurological complications Twenty-five thousand acute strokes are caused by atrial fibrillation every year. But even more frequent than symptomatic strokes are silent infarctions of the brain. Silent strokes remain undetected in most cases, but cumulate over time and progressively impair cognition. The impact ...


Investigation of Genetic Risk of Atrial Fibrillation

The atrial fibrillation (AF) is the most common cardiac rhythm disturbance that is responsible for substantial morbidity and mortality independent of associated heart disease or other risk factors. Even in the absence of preexisting cardiovascular disease, AF remains significantly associated with excess mortality rates. The current unsatisfactory treatment for AF ...

Phase N/A

Studies of Disorders and Mechanisms Related to Atrial Fibrillation Before and After DC-Conversion.

The purpose of this study is to investigate if breathing disorders are related to atrial fibrillation and if it is possible to predict recurrence of atrial fibrillation after DC-conversion by changes in heart rate variability and 24 hour ECG.

Phase N/A

Atrial Fibrillation Ablation Device Comparison Study

Surgery has been used as a treatment for atrial fibrillation (AF) for more than 20 years. Although highly successful, it has not been widely adopted because operations designed to cure AF require extensive cutting and suturing of the heart, inflicting a significant risk on the patient. Newer technologies now permit ...


Impact of Left Atrial Appendage Exclusion on Short-Term Clinical Outcomes and Long-Term Stroke Incidence

In patients with non-rheumatic atrial fibrillation, the left atrial appendage is the origin of at least 90% of all left atrial clots, and the resulting systemic emboli cause approximately 25% of all strokes. The stroke rate in patients with atrial fibrillation older than 75 years of age is 8.1% per ...

Phase N/A

Ibutilide Administration During Pulmonary Vein Ablation

To test the hypothesis that localized functional reentry maintains Afib in humans, ibutilide will be administered intravenously in patients undergoing an Afib ablation. The hypothesis of this study is that ibutilide will decrease the high frequency signals observed in Afib suggesting the presence of micro reentrant circuits as the basic ...

Phase N/A

Pulmonary Vein (PV) -Isolation: Arrhythmogenic Vein(s) Versus All Veins

BACKGROUND Atrial fibrillation ablation procedures typically involve isolation of all pulmonary veins (PVs), yet the need for such an extensive ablation strategy in all patients is unclear. OBJECTIVE: We conduct a randomized study comparing the safety and effectiveness of two interventional ablation techniques for treatment of paroxysmal atrial fibrillation: the ...


Irbesartan and Adhesion Molecules in AF

Primary Objective: The aim of the study is to assess that blocking the angiotensin II type 1 receptor reduces systemic levels of oxidative stress markers and adhesion molecules by more than 25% compared to placebo in patients with persistent/permanent atrial fibrillation. Primary Target Parameter: The primary target parameter is defined ...


The Effect of Losartan on Atrial Fibrillation (AF) Burden and Pacemaker Dependence in Patients With Sick Sinus Syndrome

Sick sinus syndrome is a common indication for permanent cardiac pacing in the community. It results from disordered impulse generation within the sinus node or impaired conduction of the impulse to the surrounding atrial tissue, thus leading to the clinical manifestation of bradycardia. In patients with SSS, AF frequently develops ...
