ETNA-AF (Edoxaban Treatment in routiNe clinical prActice in patients with nonvalvular Atrial Fibrillation) is a global programme that combines data from distinct non-interventional studies in Europe, East Asia, and Japan in a single database. A total of more than 28,000 patients will be included in the ETNA-AF registries and followed for two years (patients in Europe will be followed for four years). The primary objective of ETNA-AF is to collect information on the use of edoxaban in routine clinical practice, including the safety and efficacy profile in non-preselected patients with NVAF.1,2,3,4,5
About Atrial Fibrillation
AF is a condition where the heart beats irregularly and rapidly. When this happens, blood can pool and thicken in the chambers of the heart causing an increased risk of blood clots. These blood clots can break off and travel through the blood stream to the brain (or sometimes to another part of the body), where they have the potential to cause a stroke.6
AF is the most common type of heart rhythm disorder and is associated with substantial morbidity and mortality.7 More than six million Europeans are diagnosed with AF, and this figure is expected to at least double over the next 50 years.8,9 Compared to those without AF, people with the arrhythmia have a 3-5 times higher risk of stroke.10 One in five of all strokes are as a result of AF.9
Edoxaban is an oral, once-daily, direct factor Xa (pronounced “Ten A”) inhibitor. Factor Xa is one of the key components responsible for blood clotting, so inhibiting this makes the blood thin and less prone to clotting. Edoxaban is currently marketed by Daiichi Sankyo and its partners in more than 30 countries and regions around the world.
