Active clinical trials for "Atrial Fibrillation"

To assess the prevalence of all (prevalent and paroxysmal) undiagnosed atrial fibrillation (AF) in a Japanese population with a moderate-to-high risk of stroke

This study will retrospectively review and compare clinical outcomes between left atrial appendage occlusion with dual antiplatelet therapy versus conventional antithrombotic therapy in patients with atrial fibrillation undergoing drug-eluting stent implantation.

In Western countries, every sixth person in their lifetime and 15,000 people in Finland have a new stroke each year. About every fourth stroke is based on cardiac embolism. Atrial fibrillation causes formation of thrombi in the left atrium with ensuing embolization in the cerebral and peripheral circulation. This study investigates the suitability of measurement techniques and new calculation methods used in sport/wellness technology for the screening and diagnosis of atrial fibrillation and other arrhythmias. New measurement technologies, the one-time ECG measurement and pulse wristband measurement, are studied for their characteristics, data quality and rhythm recognition. Identifying latent arrhythmias with new self-monitoring technologies can significantly reduce the number of strokes (the latent arrhythmias causes about 25% of strokes). The research will be accomplished in cooperation with the Kuopio University Hospital Emergency Department, the Heart Center, the Department of Applied Physics of the University of Eastern Finland and Heart2Save Ltd. The results of the research project will be published in the scientific journals of medicine and medical technology and will be presented at scientific conferences of the respective fields. The research results of the project can be utilized by all companies in the medical technology industry, in particular companies that produce ECG measuring instruments and companies that produce rhythm recognition software.

Study objective is to determine whether there is an association between genetic variant risk scores and clinical outcomes (percent time in therapeutic range, time to reach therapeutic international normalized ratio (INR), INR ≥ 4, bleeding event, ischemic stroke, death) in participants taking warfarin for atrial fibrillation, deep vein thrombosis (DVT), pulmonary embolism (PE), and/or intracardiac thrombosis.

Multicentre, prospective cohort study in patients with a history of HF with preserved or reduced ejection fraction admitted to hospital with acutely decompensated HF. Eligible and consenting patients will be enrolled at 3 Hamilton, Ontario area hospitals and receive 28-day ECG monitoring implemented at the time of hospital discharge. Patients will be followed for a total of 1 year from hospital discharge.

To describe the treatment perception from patients with non-valvular atrial fibrillation (NVAF) receiving Pradaxa® or VKA for stroke prevention by using the self-estimation questionnaire of PACT-Q during a 6-month study period.

Patients with a history of atrial fibrillation (AF) who frequently attend the emergency department (ED) with symptoms may not require emergency treatment, and may be more appropriately managed in an alternative outpatient setting. This may be the result of inappropriate or inadequate advice or a lack of patient understanding. The main research objective pertains to the reason for seeking medical attention for AF in the ED, ED management of the patient, outcomes of ED care and alternative strategies.

A prospective non-interventional single-centre study aimed to evaluate actual adherence of AF patients using the validated adherence Scale. Primary Study Objective(s) Primary study objective The aim of the present study is to assess adherence to therapy and factors associated with adherence in patients with CV disease complicated by non-valvular atrial fibrillation requiring OAC treatment within the outpatient registry PROFILE (prospective, observational study). Data collection in patients with non-valvular atrial fibrillation requiring OAC treatment included in the registry Evaluation of actual patient adherence to OACs Secondary Study Objective(s) Evaluation of potential patient adherence to OACs Determination of the most significant factors associated with adherence to OACs in patients with non-valvular AF Validation of new original 5-item Questionnaire Evaluation of doctor's adherence to OAC prescription according to Guidelines (ESC). Management of atrial fibrillation,2016)

This study uses two AcQMap imaging and electroanatomical mapping systems (Acutus Medical) to simultaneously visualise and map patterns of wavefront propagation in both the left and right atria during atrial fibrillation in order to identify mechanisms of rhythm propagation and maintenance and the importance of the interaction of the left and right atria. Mapping will also be performed during pacing from different sites and cycle lengths to identify regions of abnormal conduction that may be related to the maintenance of atrial fibrillation.

This study will assess a new device, the RhythmPadBP, which detects heart rhythm and measure blood pressure simply by placing palms of the hands on a pad containing titanium electrodes.
