B-Type Natriuretic Peptide (BNP)

B-Type Natriuretic Peptide (BNP) is a hormone produced by the heart in response to increased pressure or stress, often due to heart failure or other cardiovascular issues. It helps regulate blood pressure and fluid balance. When the heart struggles to pump blood effectively, BNP levels rise, making it a useful indicator for doctors diagnosing heart-related conditions. A BNP test measures the amount of this hormone in the blood, helping healthcare providers assess heart function and determine the best treatment options for patients. High levels of BNP typically suggest heart problems.
