Characteristics of red cell distribution width in heart failure patients at Thai Nguyen National Hospital
Main Article Content
Abstract
Heart failure is a complex clinical syndrome with a rising prevalence among the elderly. Among various prognostic indicators, red cell distribution width (RDW) is considered a potential marker. A cross-sectional descriptive study was conducted on 140 heart failure patients treated at Thai Nguyen National Hospital to analyze RDW characteristics in these patients. The results showed that the median RDW was 14.3 (IQR: 13.6 - 15.5), with 57.1% of patients having RDW > 14%. RDW tended to increase with NYHA heart failure classification, being significantly higher in class III–IV compared to class I–II (p < 0.05), and showed a positive correlation with brain natriuretic peptide (BNP) levels (r = 0.404; p < 0.05). RDW > 14% was closely associated with severe heart failure (p < 0.05; OR = 4.8) and BNP > 100 ng/mL (p < 0.05; OR = 4). Although no clear relationship with ejection fraction (EF) was observed, the study results suggest that RDW is a simple hematological index that may be valuable for stratifying heart failure severity in clinical practice.
