[Association of serum uric acid, plasma NT-proBNP, Hs-C reactive protein and invasive hemodynamic parameters in patients with heart failure].
OBJECTIVE
To explore the correlation of serum uric acid, invasive hemodynamic parameters, plasma N-terminal proBNP (NT-proBNP) and Hs-C reactive protein (Hs-CRP) in patients with heart failure.


METHODS
Invasive hemodynamic parameters derived from Swan-Ganz catheter, serum uric acid, plasma NT-proBNP and Hs-CRP within 12 hours after hospital admission were analyzed in 141 patients with chronic heart failure [New York Heart Association (NYHA) class II-IV].


RESULTS
Incidence of hyperuricemia was 55.30% in this patient cohort. Pulmonary capillary wedge pressure (PCWP) and plasma NT-proBNP in hyperuricemia patients were significantly higher than those in non-hyperuricemia patients (P < 0.01). The percentages of high plasma NT-proBNP (> 600 pmol/L) and hyperuricemia were significantly higher in patients with PCWP > or = 18 and < 28 mm Hg (1 mm Hg = 0.133 kPa) and patients with PCWP > or = 28 mm Hg compared those in patients with PCWP < 18 mm Hg, (P = 0.01, P = 0.02; P < 0.01, P < 0.01, respectively). Partial correlation analysis showed that serum uric acid correlated with right atrial pressure, right ventricular pressure, pulmonary arterial pressure and PCWP (r = 0.19, P = 0.03; r = 0.45, P < 0.01; r = 0.23, P = 0.01; r = 0.24, P = 0.01, respectively). Multiple linear regression analysis showed both serum uric acid and plasma NT-proBNP correlated independently with PCWP (beta = 0.24, P = 0.01; beta = 0.47, P < 0.01, respectively) while plasma Hs-CRP and left ventricular ejection fraction were not correlated with serum uric acid and PCWP (P > 0.05).


CONCLUSIONS
Serum uric acid independently correlated with PCWP in patients with heart failure and the combined measurements of serum uric acid and plasma NT-proBNP are helpful in evaluating the prognosis of patients with heart failure.
