ObjectivesNew-onset atrial fibrillation (NOAF) during hospitalization is considered a frequent complication associated with worse outcomes in the setting of ST-segment elevation myocardial infarction (STEMI). We aimed to investigate the association of admission serum laboratory parameters, neutrophil to lymphocyte ratio (NLR), and monocyte to high-density lipoprotein ratio (MHR) with NOAF in STEMI patients treated with a primary percutaneous coronary intervention (PCI).Patients And MethodsA total of 621 patients who were hospitalized with a diagnosis of STEMI and treated with primary PCI were retrospectively enrolled in the study. NOAF during index hospitalization and overall mortality were reported as the clinical outcomes.ResultsIn our study population, 40 (6.4%) patients developed NOAF during index hospitalization. Monocyte counts, mean platelet volume (MPV), red cell distribution width (RDW), NLR, MHR, C-reactive protein (CRP), creatinine, glucose, and uric acid levels were higher in the NOAF+ group compared with the NOAF- group. In multivariate regression analysis, age, left-ventricular ejection fraction, left atrial volumes, admission heart rate, multivessel disease, increased levels of CRP, MPV, RDW, uric acid, NLR, and MHR independently predicted NOAF. In addition, NOAF was found to be an independent predictor of overall mortality in the study population.ConclusionFor the first time in the literature, admission serum levels of MPV, RDW, uric acid, NLR, and MHR were found to be correlated independently with NOAF after primary PCI.
