The term natriuretic peptide precursor generally refers to brain natriuretic peptide precursor, and brain natriuretic peptide precursor is more dangerous at 27,000 pg/ml. Brain natriuretic peptide precursor is one of the heart’s natriuretic peptides, which is a peptide composed of amino acid residues, and it is an important indicator that can reflect heart failure, and brain natriuretic peptide is often used in the clinic to assess the presence of heart failure and the severity of heart failure. The normal value of brain natriuretic peptide precursor is less than 300pg/ml, when it is more than 10,000pg/ml, it suggests that patients with heart failure have a higher risk of long-term death, so brain natriuretic peptide precursor 27,000pg/ml is more dangerous. In addition, elevated brain natriuretic peptide precursor can also be seen in sleep apnea syndrome, acute respiratory distress syndrome, sepsis and so on. It is recommended to go to the hospital for a doctor’s judgment and actively cooperate with the doctor’s treatment when you have brain natriuretic peptide precursor 27000pg/ml.
