Active clinical trials for "Atrial Fibrillation"

To obtain a better understanding on the comparative effectiveness of rivaroxaban versus VKA(Vitamin K antagonist) for stroke prevention in patients with NVAF(non-valvular atrial fibrillation) in a real-life setting

To obtain a better understanding on the comparative effectiveness of apixaban versus VKA (Vitamin K antagonist) for stroke prevention in patients with NVAF (Non-valvular atrial fibrillation) in a real-life setting.

The aim of this pilot study is to determine, as exhaustively as possible thanks to the continuous and precise recording of heart rhythm, the frequency of de novo atrial fibrillation in septic shock, which is currently unknown, and to identify specific factors that could be associated with the condition. These will be investigated more precisely in a future study. This constitutes the first step in a reflection on the management of Cardiac Arrhythmia by Atrial fibrillation (ACFA) in septic shock in Medical Intensive Care, known as a major prognostic factor for morbimortality, but for which management is uncertain in the absence of reference data.

ARENA aims to inform patients about the symptoms and the risks of atrial fibrilation. The study design includes three study arms: ARENA Intervention: This project will examine the effectiveness of population education. ARENA Medication: The aim is to examine the patient's adherence and to analyze whether there are any complications. ARENA Migration: ARENA migration aims to examine whether a targeted population education can improve the care of people with a Turkish migration background.

The aim of this study is to assess the real world comparative effectiveness of Rivaroxaban prescribed in non-valvular atrial fibrillation (NVAF) routine care patients in Germany.

This study evaluates the antithrombotic therapy in patients suffering from atrial fibrillation after stent implantation in Germany. Patients prescribed with the novel oral anticoagulant Rivaroxaban will be followed up over 14 months for their adherence to the medication schedule and for complications that occurred after index PCI.

The purpose of this study is to determine whether baroreceptor sensitivity (the ability of your body to change your heart rate and/or blood pressure in response to a situation) has any effect on how likely you are to suffer certain events after heart or lung surgery. The postoperative events that the investigators will be studying are pain after surgery, atrial fibrillation (an irregular heart rhythm), and cognitive dysfunction (a decline in mental abilities).

This study will assess the effect of apixaban on thrombotic status in patients with atrial fibrillation.In addition it will compare apixaban to aspirin and warfarin on their effect on endogenous fibrinolysis.

The aim of the study is to examine the effect of RIPC on physiological parameters in non-valvular paroxysmal atrial fibrillation. Furthermore the study will provide a unique bio-date base for further analysis of molecular and genetic mechanisms responsible for observed results. The potential effect of RIPC on AF inducibility and/or prothrombotic activity might be implemented as additional treatment component to reduce AF burden and minimize thromboembolic risk. Interim Analysis will be done after 73 patients.

Atrial fibrillation (AF) is a common condition whose prevalence increases with advancing age . One of the main complications of this arrhythmia is the occurrence of systemic thromboembolism, the first of which the occurrence of cerebrovascular accident (CVA) . The advanced age itself is an independent risk factor for occurrence of stroke in the context of AF , evidenced by the score awarded to the age over 75 years in the risk estimate thromboembolism in the score CHA2DS2-Vasc . Making the elderly a priority target for the prevention of thromboembolism, both because of the increased thromboembolic risk and prevalence of AF in this population. For many years, vitamin K antagonists (VKA) have proven their effectiveness in this context . But the effectiveness and safety of thromboembolism prevention by anti-vitamin K treatment involves maintaining the INR (International Normalized Ratio) in the therapeutic range. Indeed occurred of a thromboembolic or haemorrhagic adverse event directly correlates to having an INR outside the therapeutic range and maintaining the INR in the therapeutic range is subject to many variations inter- and intra-individual. They include, genetic factors , food , drug interactions , as well as disease processes . Or one of the elderly characteristics is the coexistence of multiple pathological processes or comorbidities . The supposed interaction between comorbidities and variability of INR has been little studied: Only a few studies have examined the factors associated with the stability of the INR and unstable . The identification of patients at risk of instability INR yet allow clinicians greater vigilance and better identification of patients for whom the initiation of treatment with vitamin K does not appear the best therapeutic strategy. Our study seeks to determine whether comorbidity, assessed by the Charlson comorbidity index, are associated with instability of the INR, among more than 80 years for patients treated with AVK atrial fibrillation.
