What is type b pro-brain natriuretic peptide?

B-type natriuretic peptide (BNP) is a biologically active natural hormone synthesized by cardiac muscle cells. It is mainly located in the heart ventricle. When ventricular dysfunction occurs, b-type natriuretic peptide is rapidly synthesized and released into the blood, which helps to regulate heart function. In blood tests, b-type natriuretic peptide can be found to increase, thus indirectly judging the strength of cardiac ventricular function. This test is mainly used to diagnose heart failure, evaluate the efficacy and prognosis of anti-heart failure drugs, and at the same time, it is used for patients with acute myocardial infarction to evaluate the recovery of their heart function after treatment.
