NT-proBNP (N-Terminal Pro B-type Natriuretic Peptide)

The NT-proBNP (N-terminal pro-B-type natriuretic peptide) test is used to measure the levels of NT-proBNP in the blood. NT-proBNP is a hormone produced by the heart in response to increased blood pressure or stress on the heart muscle. It helps diagnose and manage heart-related conditions, such as heart failure

Why consider this test?

• Heart failure diagnosis: It helps determine if heart failure is the cause of symptoms such as shortness of breath or fluid retention.
• Risk stratification: For patients with known heart disease, it can help predict the risk of adverse cardiovascular events, such as heart attack or stroke.
• Monitoring treatment: NT-proBNP levels can be used to track the effectiveness of treatment in heart failure patients.

Who should get this test done?

• Individuals with symptoms of heart failure (e.g., fatigue, shortness of breath, edema, or chest pain).
• People with a known history of heart disease, high blood pressure, or diabetes.
• Patients with unexplained cardiovascular symptoms or when heart failure is suspected.
• Individuals experiencing acute conditions like myocardial infarction (heart attack).

More information

An NT-Pro BNP test measures the concentration of NT-proBNP (N-terminal pro-B-type natriuretic peptide) in the blood. It is a cardiac hormone secreted from the left ventricles (the organ's main pumping chamber) and helps to regulate blood volume. When heart failure develops or worsens, the heart muscle cells produce NT-Pro BNP, which is released into the bloodstream. It helps alleviate the condition by relaxing the blood vessels, reducing fluid volume, and reducing the heart's workload.
