Active clinical trials for "Atrial Fibrillation"

The purpose of this study is to evaluate the APIXABAN use in the Prevention of Stroke and Systemic Embolism in Patients with Atrial Fibrillation in Real-Life Setting in France, data from SNIIRAM (French data base).

The overall goal of this retrospective registry study is to investigate the burden-of.illness in atrial fibrillation (AF) in Denmark. Several Danish registries will be utilized to collect information on the diseases epidemiology including incidence and prevalence of AF and stroke as well as a stroke risk stratification of the Danish AF-population, the clinical and economical burden (in terms of direct and indirect cost) of AF and stroke to Danish patients, healthcare providers / healthcare system and society as well as describing treatment patterns with anticoagulant agents and their consequences in terms of stroke, bleeds, death and according cost in a real-life setting.

The aim of the study is to the reliability and feasibility of a novel optical heart rate monitor in hospital patients. Especially patients with atrial fibrillation are included. Patients will be monitored for two hours during routine post-operative care. The data from study device will be compared to routine monitoring. The design of the study is a Pilot feasibility study.

The risk of stroke is markedly elevated in patients with atrial fibrillation (AF). Oral anticoagulation (OAC) is indicated in individuals with moderate and high risk of stroke to the disadvantage of an increased burden from bleeding. Adequate knowledge of this disorder and understanding the benefits and hazards of antithrombotic treatment are essential to incorporate patient´s values and preferences in these decisions. This will further improve acceptance of recommended therapy and augment compliance with OAC. The objective of this investigation is to compare patient´s perceptions and physician´s assessments of benefits and risks of OAC.

The main objective of the study is to assess preferences of Non Valvular Atrial Fibrillation (NVAF) patients towards different options of an anticoagulation treatment. Patient preferences for anticoagulant treatment attributes (convenience attributes only), based on a Discrete Choice Experiment(DCE) interview will be elicited and the impact of switching from Vitamin K Antagonist(VKA) to Xarelto® on Atrial Fibrilation(AF) patient treatment satisfaction will be documented, measured by score differences of the Anti-Clot Treatment Scale (ACTS) score in patients switching from VKA to Rivaroxaban.

The purpose of this research is to test the clinical value of a new P-wave sensitive recording vector compared to a standard ECG limb lead II vector from similar easy-to-use long-term cardiac rhythm monitoring patch systems, the Carnation TM Ambulatory Monitoring (CAM) System and the Zio-XT iRhythm. The P-wave is a critical aspect of the electrocardiogram. The purpose of this study is to see if the P-wave centric focus of the CAM system improves arrhythmia diagnosis.

The objective of this study was to investigate whether there is a link between clinical and biological variables and bioassay high xaban in elderly patients as part of an unscheduled hospitalization.

One of the biggest limitations of the currently used percutaneous techniques for Pulmonary Vein Isolation (PVI) in the setting of atrial fibrillation ablation is the lack of real-time information about the left atrial (LA) wall thickness and about its acute changes during energy delivery for ablation. This makes difficult to predict the achievement of transmural lesions, to identify the possible causes of ablation failure and also to avoid the occurrence of perforation and/or other collateral damage. Computed tomography (CT) is a reliable technique for measurement of the LA wall thickness but it cannot be used during the ablation procedure and its extensive use is limited by the need of ionizing radiation. Preliminary data from animal studies support the accuracy of real-time ultrasound imaging modalities such as intracardiac echocardiography (ICE) or Intravascular Ultrasound (IVUS) imaging for measurement of LA wall thickness and monitoring of its acute changes related to catheter ablation. The pilot study INSIDE PVs has been primarily designed to evaluate the feasibility and accuracy of intravascular imaging techniques for real-time imaging of the LA wall thickness during AF ablation.

The primary objective is to assess the proportion of Non-valvular atrial fibrillation (NVAF) patients receiving the standard dose of 20 mg of rivaroxaban or the reduced dose of 15 mg of rivaroxaban. The secondary objective is to determine if dosing patterns for rivaroxaban may be influenced by baseline chronic kidney disease (CKD) status (as a proxy for measured baseline renal function).

describe the sociodemographic and clinical characteristics of patients diagnosed with non-valvular atrial fibrillation (NVAF) at risk of stroke or systemic embolism on anticoagulant therapy who have changed their therapeutic regimen, due to any clinical situation, based on the doctor's routine clinical practice and are currently on treatment with a direct oral anticoagulant (DOAC)
