The aim of the research was to evaluate predictors of postsurgery atrial fibrillation (AF) in patients with coronary artery disease (CAD) after coronary artery bypass grafting (CABG). This prospective one-center study included data received at clinical and instrumental evaluation of 174 patients with CAD. Atrial fibrillation at early postsurgery period was diagnosed by continuous ECG monitoring during 48–72 hours, routine registration of 12-lead ECG and Holter ECG monitoring. It was established that AF appeared in 33% patients after CABG, in 49.1% after CABG combined with valve surgery. The main pre-surgery factors of AF appearance were diabetes
mellitus, left ventricular aneurysm, decreased left ventricular ejection fraction, absence of preventive treatment with beta-blockers, angiotensin-converting enzyme inhibitors and statins. Duration of artificial circulation and aorta clamping were intra-surgery factors, while increase of C-reactive protein was a post-surgery factor of AF appearance.
