About

Atrial fibrillation (AF) is type of arrhythmia characterized by an irregular and often rapid heartbeats, it has strong associations with other cardiovascular diseases, such as heart failure, coronary artery disease (CAD), valvular heart disease, diabetes mellitus, thyrotoxicosis and hypertension.

Atrial fibrillation is the most frequent cardiac arrhythmia. It has been estimated that 6-12 million people worldwide will suffer this condition in the US by 2050 and 17.9 million people in Europe by 2060. Atrial fibrillation is a major risk factor for ischemic stroke and provokes important economic burden along with significant morbidity and mortality .

(AF) is arrhythmia with the potential to cause thromboembolism. Studies suggest that AF increases the risk of stroke five-folds. Stroke prevention is central to the management of patients with atrial fibrillation (AF), and effective stroke prevention requires oral anticoagulation (OAC). Either a vitamin K antagonist (VKA; e.g. warfarin) or a non-VKA oral anticoagulant (NOAC) .

It's essential reach the balance between prevention of thromboembolic as well as bleeding events during the anticoagulant use.
