Atrial fibrillation (AF) is the most common sustained arrhythmia with an estimated prevalence in adults as high as 4%. AF negatively affects the quality of life and it is associated with incident adverse cardiovascular events and two-fold higher mortality. Lifetime risk of AF increases with age but many other risk factors such as diabetes, chronic kidney disease, hypertension and obesity may promote its development. Owing to the shared risk factors, AF and coronary artery disease (CAD) can both be found in the same patient at some point in life [1].
