Atrial fibrillation (AF) represents the most common supraventricular arrhythmia in elderly [1]. It was estimated that 1 % to 3 % of the world population suffers from AF, with higher prevalence in the elderly population (8–10 %) and in patients with other comorbidities [2]. This number is destinated to rise as it is directly related to ageing population [3]. AF is more prevalent in male population with ratio of 2:1 than women [4]. AF has been established to increase the risk of ischemic stroke, myocardial infarction, heart failure (HF), sudden death and overall cardiovascular mortality in both males and females [5,6].
