Active clinical trials for "Atrial Fibrillation"

The purpose of this study is to test the hypothesis that treatment with the angiotensin II type 1 receptor antagonist candesartan may reduce the recurrence rate of atrial fibrillation after electrical cardioversion.

A suboptimal level of resynchronization (cardiac resynchronization therapy [CRT]) achieved in many patients with actual standards and techniques based on tissue-Doppler echocardiography could be more effective to obtain better CRT results. Eligible patients who successfully received atrioventricular (AV) junction ablation and biventricular (BiV) pacing are randomised to a comparison between a strategy of right ventricular (RV) apical pacing with delayed CRT based on clinical indications with a strategy of early optimal CRT based on an echocardiographic stratification. End-points: Acute echo comparison (acute echo study) Quality of life and exercise tolerance (Short-term clinical study) Composite end-point of CRT clinical failure (Long-term clinical study)

Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with substantial morbidity and mortality. Present treatment strategies are aimed at termination of AF and prevention of AF recurrence using antiarrhythmic drugs or heart rate control drugs. Drugs are not always well tolerated, so atrial pacing as a strategy for prevention of atrial tachyarrhythmias is being explored. The AT501 pacemaker has both "prevention" and "treatment" algorithms for atrial tachyarrhythmias. The investigators wish to determine whether these special features, over the long term, decrease the amount of time the person experiences AF.

The purpose of this study is to demonstrate the safety and efficacy of RSD1235 compared to placebo in the conversion of atrial arrhythmia to sinus rhythm in subjects following valvular and/or coronary artery bypass graft surgery.

Patients with cardiac pathology and arrhythmias including those who have indications for pacemakers implantation will be included in the study. We will determine the influence of pacemaker implantation with the localization of the ventricular electrode in the top of the right ventricle or the middle third of the right ventricle according to echocardiographic and electrocardiographic parameters, congestive heart failure progression, patients' quality of life and follow-up therapy of patients with identified myocardial fibrosis with existing pacemaker. Study of changes in echocardiography, electrocardiography, myocardial fibrosis markers, the quality of life of patients will allow to choose the most optimal localization of the ventricular electrode during implantation of the permanent pacemakers system in order to improve the quality of life of the patients.

The purpose of this study is to look at how many patients with AF had strokes, major bleeding and death in both people who had and had not taken any oral anticoagulant. Atrial fibrillation (AF) is an irregular and often very rapid heart rhythm (arrhythmia) that can lead to blood clots in the heart. This increases the risk of stroke. Anticoagulants are medicines, also called blood thinners, which help prevent blood clots from forming or getting bigger. This study includes patient's data from the database who: Had at least one hospital stay with AF Are new users of OACs for AF treatment Are 18 years and older when they were confirmed to have AF All the patient's data included in this study would have either received the OAC therapy or not. This study aims to look at any events of strokes, major bleeding and death. The data of patients will be collected from the French national health insurance claims database (SNDS). The planned study period is thought to be from 1st January 2016 till 31st December 2020

The purpose of this study is to study clinical factors and (blood) biomarkers related to progression of Atrial Fibrillation (AF) in patients diagnosed with self-terminating AF with special reference to hypercoagulability. All patients will be continuously monitored for their atrial rhythm to assess AF progression, either through an implantable loop recorder (Reveal LinQ) or via the atrial lead of a cardiac implantable electronic device (CIED), both in combination with the CareLink home monitoring system. Remote monitoring and interrogation will be installed and used on a daily basis.

This is a prospective, randomized, open-label, blinded end-point evaluation trial. The patient population consists of patients on hemodialysis who have atrial fibrillation (AF) and end-stage renal disease (ESRD) .

The primary objectives of this study are to compare the risk of major bleeding and stroke/systemic embolism (SE) events among oral anticoagulant (OAC)-naïve non-valvular atrial fibrillation (NVAF) patients initiating OAC warfarin or apixaban or dabigatran or rivaroxaban treatment.

Oral carvedilol administered in escalating doses in patients with atrial fibrillation among patients with AF with fast ventricular rate.
