Active clinical trials for "Atrial Fibrillation"

Atrial fibrillation (AF) is the most common cardiac arrhythmia associated with excessive risk of ischemic stroke and heart failure as well as reduced life expectancy. On the other hand, chronic coronary syndromes (CCS) remains the main cause of morbidity and mortality in an aging population. Both disease entities share common risk factors such as hypertension, diabetes and obesity The purpose of the study is to investigate the hypothesis indicating lack of significant coronary lesions in AF vs. sinus rhythm (SR) patients.

The purpose of this observational study is to understand real-world oral anticoagulants (OAC) (warfarin, apixaban, dabigatran, edoxaban and rivaroxaban) usage for non-valvular atrial fibrillation (NVAF) patients.

Atrial fibrillation (AFib) represents the most frequent cardiac arrhythmia whose prevalence appears to be increasing in the general population. Furthermore, this arrhythmia determines an increased risk of neurological complications (stroke) and, consequently, of mortality and morbidity. Currently, the first choice for the treatment of AFib is represented by the use of antiarrhythmic drugs. In patients who do not respond to pharmacological treatment, the ESC 2016 European guidelines recommend the execution of transcatheter ablation (Class I, level of evidence A). However, minimally invasive pulmonary vein isolation surgery (PVI) is recommended for subjects who are not even responsive to transcatheter ablation (Class IIa, Level of Evidence B). Previous studies have demonstrated good short-term results of thoracoscopic AFib ablation using PVI, with a 1-year freedom from atrial fibrillation recurrence without antiarrhythmic drugs of approximately 64-73%. However, only a few authors have described the medium-long term follow-up outcomes. The aim of this study is to report the long-term follow-up data of ablation of isolated, predominantly paroxysmal atrial fibrillation performed by isolation of the pulmonary veins by radiofrequency in bilateral thoracoscopy.

To characterize and estimate the incidence rate of new-onset atrial fibrillation (NOAF) in patients with acute myocardial infarction (MI). To explore the prognostic influences of NOAF on MI patients' clinical outcomes. To further investigate the impact of NOAF associated characteristics on patients' clinical outcomes eithier during hospitalization or follow-up period.

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.

It is an observational study in patients with heart failure investigating the incidence of arrhythmias using a wearable device which can monitor heart rhythm for up to 14 days. In addition to gathering routine clinical information, research assessments include a symptoms questionnaire and a corridor walk test. Patients will be followed for clinical events (interventions for arrhythmias, hospitalisation, death) for 1 year.

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 aim of this non-interventional study is to describe patient's perception of anticoagulant treatment when using Pradaxa® to prevent stroke and systemic embolism while suffering from atrial fibrillation (according to its approved indication in the approved dosages of 110 mg or 150 mg twice daily) in comparison to standard care using Vitamin K Antagonist (VKA).

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)

This is a prospective, multi-center, randomized, pilot study comparing the WATCHMAN left atrial appendage occlusion device with Rivaroxaban therapy in patients with non-valvular atrial fibrillation.
