Natriuretic Hormone (B-type) N-terminal Propeptide (NT-proBNP, N-Terminal Pro-brain Natriuretic Peptide, Pro-B-Type Natriuretic Peptide)

The interpretation of the research results contains information for the attending physician and is not a diagnosis. The information in this section cannot be used for self-diagnosis and self-medication. An accurate diagnosis is made by a doctor using both the results of this examination and the necessary information from other sources: anamnesis, results of other examinations, etc. Units of measurement: pg/ml . Alternative units: pmol/L. Conversion factors: pg/ml × 0.118 → pmol/l. Reference values To exclude chronic heart failure, use: - threshold <125 pg/ml for age up to 75 years; - the threshold is <450 pg/ml for the age over 75 years. To exclude acute heart failure: - threshold <300 pg/ml. Interpretation of the results of the study of Natriuretic hormone (B-type) N-terminal propeptide Increasing values Heart failure. Hypertrophy of the left ventricle. Inflammation of the heart tissues – myocarditis, rejection of a heart transplant. Arrhythmogenic right ventricle with reduced ejection fraction. Kawasaki disease. Primary pulmonary hypertension. Acute coronary syndrome. Pulmonary embolism. Overload of the right ventricle. Renal insufficiency (accumulation due to decreased clearance of NT-proBNP). Ascitic cirrhosis. Endocrine disorders (primary hyperaldosteronism, Cushing's syndrome). Acute myocardial infarction (BNP release as a result of tissue necrosis). Old age. Lowering the values Obesity (changes in metabolism and clearance of NT-proBNP).
