General information

NT-proBNP (N-terminal pro b-type natriuretic peptide) is a biomarker released by the heart, especially when the cardiac muscle is under stress due to stretching or increased pressure—typically in heart failure.

• Diagnosing heart failure – especially in people with symptoms like shortness of breath, swelling, or fatigue.

• Assessing severity – higher levels generally reflect more advanced heart dysfunction.

• Monitoring treatment response – falling levels can indicate improvement.

• Risk evaluation in acute coronary syndromes – can help predict complications.

• Checking for cardiac strain during chemotherapy – especially with drugs that can affect the heart.

• Sampling: venous blood. Results same day.
