With regards to biomarkers, the values of white blood cell counts, neutrophil counts, monocyte counts, NLR, MLR, SIRI, glucose, and HDL-c were significantly higher in individuals who suffered from NOAF compared with NOAF-free subjects, while NOAF patients had significantly lower levels of hemoglobin, lymphocyte counts, platelet counts, LDL-c, eGFR as well as albumin compared to non-AF patients. This evidence concerns the gene ALB and atrial fibrillation.
