Özet
Aim: Heart failure (HF), a progressive disease, is accompanied by chronic inflammation and changes in osmolality. The neutrophil-to-lymphocyte ratio (NLR) demonstrates a sys- temic inflammatory response in most diseases; however, the relationship between plasma osmolality and the systemic inflammatory response in HF patients is not yet clear. There- fore, we aimed to investigate the possible associations of NLR with plasma osmolality levels in patients with HF. Materials and Methods: The present study included 189 consecutive patients with chronic HF with an ejection fraction (EF) of <40%. They were classified into four groups based on admission plasma osmolality quartiles: hypo-osmolar (first quartile), normo- hypo-osmolar (second quartile), normo-hyperosmolar (third quartile), and hyperosmolar (fourth quartile). We evaluated the relationship between NLR, plasma osmolality, type-B natriuretic peptide (BNP), and the New York Heart Association (NYHA) functional class. Results: The hyperosmolar group had an increased NLR (p = 0.007). The presence of NYHA class 3–4 functional capacity, high-sensitivity C-reactive protein, and high osmo- lality were independent predictors of increased NLR. In correlation analysis, osmolality was significantly positively correlated with NLR (r = 0.201, p = 0.011). Conclusion: Higher NLR values may be associated with increased plasma osmolality, which may indicate an increased inflammatory status in the HF phenomenon.
