Abstract:
Objective: To explore correlation between serum uric acid (UA) level and heart failure severity in patients with chronic pulmonary heart disease (CPHD).Methods:According to New York Heart Association (NYHA) cardiac function classification, a total of 98 CPHD patients were divided into class I~II group (n=36), class III group (n=31) and class IV group (n=31).Another 30 healthy subjects were enrolled as healthy control group simultaneously.Serum UA level was measured in all groups.Real time three-dimensional color Doppler echocardiography was used to measure left ventricular ejection fraction (LVEF) and left ventricular end-diastolic dimension (LVEDd), and the results were compared among all groups.Results: Compared with healthy control group, there were significant rise in serum UA level[(342.4±101.7) μmol/L vs.(459.6±110.3) μmol/L]and incidence rate of hyperuricemia (33.33% vs.58.16%) in CPHD group, P<0.05 both;along with NYHA class increased, there were significant rise in serum UA level[(350.7±103.4) μmol/L vs.(422.3±106.7) μmol/L vs.(491.8±113.2) μmol/L], LVEDd [(59.2±10.1)mm vs.(64.3±9.8)mm vs.(68.9±10.6)mm], and significant reduction in LVEF[(37.7±9.8)% vs.(31.9±8.6)% vs.(28.4±8.1)%]in CPHD patients, P<0.05 all;linear correlation analysis indicated that serum UA level was significant positively correlated with LVEDd (r=0.67, P=0.026), and significant inversely correlated with LVEF (r=-0.86, P=0.033).Conclusion: Serum uric acid level can be used as a reliable index evaluating heart failure severity in patients with chronic pulmonary heart disease.
