Cirakoglu OF, et al. - In this prospective, single-center, cross-sectional study, researchers examined the link between Syntax score (SS) and new-onset atrial fibrillation (NOAF) with known predictors of atrial fibrillation. This study included 692 consecutively enrolled patients with a first-time diagnosis of coronary artery disease. Findings revealed the possible utility of SS to help detect patients who would suffer atrial fibrillation in the setting of acute coronary syndromes (ACS). Higher SS was seen in patients with NOAF had higher SS. For NOAF development, the optimal cut-off value for SS was 18, with 82% sensitivity and 68% specificity.
