BNP Interpretation for Heart Failure

Interpret B-type natriuretic peptide (BNP) for heart failure evaluation. BNP below 100 pg/mL: HF unlikely. BNP 100-500 pg/mL: heart failure possible, consider other causes. BNP above 500 pg/mL: heart failure highly likely. BNP is secreted by ventricular myocytes in response to increased wall stress from volume or pressure overload.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Interpret B-type natriuretic peptide (BNP) for heart failure evaluation. BNP below 100 pg/mL: HF unlikely. BNP 100-500 pg/mL: heart failure possible, consider other causes. BNP above 500 pg/mL: heart failure highly likely. BNP is secreted by ventricular myocytes in response to increased wall stress from volume or pressure overload

Each component has a specific meaning:

  • Volume or pressure overload — The volume or pressure overload recorded for the scenario being assessed.

Note: Interpret the bnp interpretation result against the thresholds and context described above.

How to Use

Enter the volume or pressure overload for the scenario you are assessing. Interpret B-type natriuretic peptide (BNP) for heart failure evaluation. BNP below 100 pg/mL: HF unlikely. BNP 100-500 pg/mL: heart failure possible, consider other causes. BNP above 500 pg/mL: heart failure highly likely. BNP is secreted by ventricular myocytes in response to increased wall stress from volume or pressure overload. Use the bnp interpretation result to inform your calculation.
