Abstract/OtherAbstract:
OBJECTIVES: Neopterin, a marker of inflammation and monocyte activation, is found increased in patients with heart failure (HF). This study investigates whether neopterin levels correlate with left ventricular (LV) remodeling and brain natriuretic peptide (BNP), a marker of cardiac stress, in chronic HF (CHF) patients with different severity of disease. DESIGN AND METHODS: The relationship between neopterin and LV dimensions, NT-proBNP, and pro-inflammatory cytokines were studied in 98 CHF patients, while nineteen healthy subjects were enrolled as controls. Nineteen (19%) patients were in NYHA class I, 38 (39%) in NYHA class II, 27 (28%) in NYHA class III, and 14 (14%) in NYHA class IV. RESULTS: Neopterin levels were higher in CHF patients than in age- and gender-matched healthy controls, and related with indexed LV end-diastolic volume (LVEDVi). Prospectively CHF patients were separated into tertiles of low, medium and high neopterin levels. Among patients, male gender, LVEDVi, diuretic treatment, NYHA class I, NT-proBNP and IL-8 levels were significant determinants of urine neopterin levels by bivariate analysis. Neopterin levels were associated only to LV remodeling, as assessed by LVEDVi, and IL-8 levels, a crucial monocyte chemoattractant, by multivariate ordinal regression analysis. CONCLUSIONS: The relationship between elevated neopterin levels and LV enlargement in CHF patients suggests a crucial role of monocyte activation in the development of cardiac dysfunction in CHF patients. Assessment of neopterin levels are a potential biomarker to evaluate the progression of LV remodeling in CHF patients.
