Which diagnosis is most consistent with BNP 130 ng/L and NT-proBNP 230 pg/mL?

Natriuretic peptides rise when the heart experiences increased wall stress from fluid overload or elevated filling pressures. They’re useful in confirming heart failure because their levels track with ventricular stretch and dysfunction. A BNP level of 130 pg/mL is above the common threshold used to raise suspicion for heart failure, and an NT-proBNP of 230 pg/mL, while variable with age and other factors, is also elevated and supports increased cardiac filling pressures. Taken together, these values point toward heart failure as the most likely diagnosis. While acute coronary syndrome and pulmonary embolism can cause some elevation of natriuretic peptides, BNP and NT-proBNP are most diagnostic when the pattern reflects sustained ventricular overload consistent with heart failure. Normal aging can cause mild increases, but the magnitude here is more in line with heart failure.
