ALB and atrial fibrillation: Their findings revealed that patients diagnosed with HF exhibited elevated levels of NLR and PLR.[32,33] Some value exists for serum albumin and diagnostic nutritional indices in predicting long-term mortality in HF.[34–36] In addition, a study of 3784 patients with atrial fibrillation showed that biomarkers of inflammation strongly predicted HF hospitalization.[37] Our current study has found a positive relationship between SII and HF, consistent with previous research.
