Predictability of Atrial Fibrillation in Patients having Coronary Artery Bypass Graft Surgery, Based on Selvester Score

Aim: Patients having coronary artery bypass graft (CABG) surgery are influenced mostly by atrial fibrillation (AF), with the peak incidence of 16-44%. Due to post-operative AF (POAF), patients may be hospitalized for longer periods, require intensive care unit care again, necessitate more healthcare resources and even undergo congestive heart failure or stroke. Recent studies have shown that the size of the ventricular scar might be used as an indicator in the pathophysiology of AF. Selvester score was developed for the measurement of myocardial scar volume in patients with abnormal ventricular conduction, reporting its prognostic value in AF. Thus, we aim to investigate a likely relationship of POAF and the Selvester scoring system. Materials and Methods: This retrospective study included 180 patients with CABG from 2017 August to 2018 September. The obtained data had been analyzed in separate cohort of patients with POAF (n=50) and with post-operative sinus rhythm (PSR) (n=130). Intergroup comparisons were made using Selvester scores in particular. Results: The POAF group had higher Selvester scores (p
