Active clinical trials for "Atrial Fibrillation"

The present study will be conducted to assess the following research questions in real-life conditions in France: What are the patient and disease characteristics, comorbidities and treatment history in NVAF patients initiating a new Anticoagulant (AC) treatment, according to treatment currently available and prescribed (apixaban, other NOACs, VKAs), and are the AC-naive patient profiles different from one treatment pattern to another when initiating a new AC treatment? What are the HCP's reasons for discontinuing the previous AC strategy for initiating and choosing the newly initiated AC treatment in NVAF patients? What are the conditions of newly-initiated apixaban prescriptions in NVAF patients: prescriber, proportion of naïve/experienced patients, daily dosage and number of daily doses?

The purpose of this study is to compare the risk of major bleeding event among nonvalvular atrial fibrillation patients treated with warfarin, apixaban, dabigatran and rivaroxaban.

To characterize treatment patterns and healthcare resource utilization among adults diagnosed with non-valvular atrial fibrillation (NVAF) from the private setting in Venezuela.

This study will evaluate whether a gene marker can improve the identification of atrial fibrillation in patients with ischemic stroke, and evaluate whether the decision to anticoagulate could be improved by a marker of atrial fibrillation.

The multicenter registry will collect clinical data from 1600 patients with non valvular atrial fibrillation (NVAF) and chronic kidney disease (eGFR 15-49 mL/min per 1.73 m2). The overall objective of this registry is to assess chronic kidney disease (CKD) progression and clinical outcomes with regard to anticoagulation strategies in NVAF patients with eGFR 15-49 mL/min per 1.73 m2 in routine clinical practice.

Many drug interactions with Warfarin are well documented in the literature, including interactions with a variety of antibiotics. However,in mamy cases it is difficult to predict when the interaction remains theoretical and when it becomes clinically significant and will be reflected in the individual patient. This study's aim is to identify and characterize related conditions (including comorbidities, laboratory test results and other parameters related to the patient)that might be predictors for drug interactions turning from theoretical to clinically significant.

According to data from high volume Centres, documentation of entry block with the Achieve catheter may be possible in only about to 50% of pulmonary veins. The investigators aim to assess strategies using the Achieve catheter that can improve this performance.

ELITE (Eliminate Thromboembolism: Improving Anticoagulation in Non-valvular Atrial Fibrillation Patients) is a two year research project to assess warfarin management issues faced by atrial fibrillation (AF) patients in ambulatory settings.

Given the advances in Atrial Fibrillation (AF) management and the availability of new European Society of Cardiology (ESC) guidelines, there is a need for the systematic collection of contemporary data regarding the management and treatment of AF in the member ESC countries. It is now nearly 10 years since the last European registry of AF management was undertaken (as part of the ESC Euro Heart Survey programme), and a new registry was needed.

Patients with implantable heart devices including pacemakers, defibrillators, and cardiac monitors may not seek regular medical care related to their implanted devices. These devices are capable of detecting abnormal heart rhythms or other device abnormalities that may benefit from clinical action or oversight. A novel healthcare information technology has been developed and is being implemented clinically for screening of patients with cardiac rhythm devices who seek care in the emergency room setting. This study seeks to examine differences in detection of cardiac rhythm disturbances including atrial fibrillation (AF) with utilization of this new screening technology, and how often treatment plans change in patients who have a heart rhythm abnormality detected.
