Abstract

 Introduction. Since the level of B-type natriuretic peptide (BNP) increases in HEART FAILURE, elevated plasma BNP concentration is used as a predictor in the diagnosis and management of HEART FAILURE. Due to the diminished renal clearance of BNP, its level is above normal in kidney failure. This study evaluated the BNP prognostic value for assessing ventricular function in patients with CHRONIC KIDNEY DISEASE.Materials and Methods. All the participants were diagnosed with CHRONIC KIDNEY DISEASE. Echocardiography was employed to assess ejection fraction. Body mass index, serum creatinine, and BNP were measured for all the patients. Prognostic value of BNP was assessed for ventricular function measured by ejection fraction.Results. Forty-four patients, including 34 men and 10 women, participated in the study. Level of BNP had a significant correlation with body mass index, ejection fraction, age, and gender. The sensitivity and specificity of BNP levels of 150 pg/mL and 705 pg/mL were 93.3% and 28.6% and 50.0% and 85.7%, respectively, for the diagnosis of ventricular dysfunction in the patients with CHRONIC KIDNEY DISEASE.Conclusions.These findings suggest that a level of BNP of 705 pg/mL is a rather acceptable predictive factor for HEART FAILURE in patients with CHRONIC KIDNEY DISEASE. The participants’ height and weight, which were associated with BNP as body mass index, contributed to this level.
