Abstract
BACKGROUND: It has been reported that elevated serum uric acid (UA) levels is an independent factor of poor prognosis in patients with chronic heart failure and chronic kidney disease (CKD). OBJECTIVES: In our study, we assessed the potential impact of hyperuricemia on left ventricular (LV) diastolic dysfunction (DD) in patient with CKD. MATERIAL AND METHODS: The study group consisted of 50 patients with CKD, stages 2-5. Standard echocardiography and tissue Doppler imaging (TDI) were performed. The levels of UA and N-terminal prohormone brain natriuretic peptide (NT-proBNP) were determined. Patients were divided into two groups according to the results of peak mitral annular early diastolic velocity (EmLV): group with LV diastolic dysfunction (EmLV < 8 cm/s) DD (+) and group with normal LV diastolic function DD (-), when EmLV ≥ 8 cm/s. RESULTS: Patients DD (+) group, as compared to DD (-) patients were characterized by significantly higher serum UA levels [6.7 (4.4-14.3) mg/dL vs 5.8 (1.9-8.9) mg/dL, p = 0.004] respectively. The area under the receiver operating characteristic (ROC) curve was of serum UA levels for the detection of LV diastolic dysfunction was 0.734, 95% confidence interval (CI) 0.590-0.849, p = 0.001, whereas ROC derived UA value of > 6.0 mg/dL was characterized by a sensitivity of 76.9% and specificity of 62.5% for diagnosing LV diastolic dysfunction. The independent variable predicting LV diastolic dysfunction as measured by a multivariate logistic regression analysis was UA level > 6.0 mg/dL with odds ratio (OR) = 14.3 (95% CI 2.0-103.2), p = 0.006. CONCLUSIONS: Hyperuricemia is an independent predictive factor for LV diastolic dysfunction in patients with CKD.
