Abstract

Objective: Identify the role of NT-proBNP testing in heart failure diagnosis and to determine the association between NT-proBNP and grading of heart failure in patients with chronic renal failure, who were having periodic dialysis. Subject and method: Cross-sectional study of 76 patients. Result: The best cut point of the concentration of NT-proBNP which has diagnostic value for heart failure in patients with chronic renal failure, who were having periodic dialysis is 1802 pg/ml (NT-proBNP testing had a sensitivity of 88.64% and a specificity of 84.37%, area under the curve AUC is 0.945). NT-proBNP concentration increases with the level of heart failure: Level | (2708.25 + 1314.36 pg/ml), level || (8098.77 + 4523.40 pg/ml), level ||| (14748.50 + 9012.24 pg/ml) and level IV (30843.50 + 9902.04 pg/ml). Conclusion: There are positive correlation between the concentration of NT - proBNP and the level of heart failure.
