Abstract

New onset atrial fibrillation (NOAF) in the case of acute myocardial infarction appears to be associated with inflammation. However, its influence alongside other risk factors is currently unknown. In this study, the effect of inflammation in predicting NOAF independent of left atrial volume index (LAVi) was investigated with a new marker, the C-reactive protein/Albumin ratio (CAR). We included 945 ST-elevation myocardial infarction (STEMI) patients who underwent pPCI. Two groups were defined according to the presence of NOAF and the groups were compared for demographic, clinical and angiographic findings. Predictors of the NOAF were assessed by multivariable regression analysis. Fifty-five (5.8%) patients had NOAF after the procedures. CAR was substantially higher in patients with NOAF (5.9 [4.9] vs 0.46 [1] p
