ABSTRACT
The authors sought to investigate whether serum uric acid levels are associated with systolic left and right ventricular function, as well as left atrial function in patients with newly diagnosed heart failure. The authors enrolled 106 consecutive patients (mean age 65+/-13 years). Echocardiographic and biochemical assessment was performed during the third day of hospitalization. Pulsed tissue Doppler imaging of the systolic function of mitral and tricuspid annulus was characterized by the systolic waves (Smv and Stv, respectively), expressed in cm/s, and the left atrial function by the Amv wave. Left atrial kinetics was calculated using an equation. Serum uric acid levels were inversely correlated with Stv (P=.005) and left atrial kinetics (P=.05), after controlling for potential confounders. Uric acid levels appear to be correlated with more impaired right ventricular systolic function and decreased left atrial work in patients with heart failure.
