Heart failure index normal range

Common indicators of heart failure index include brain natriuretic peptide, amino-terminal pro-brain natriuretic peptide, ejection fraction, etc. Specific analysis is as follows:

1.

The normal value of brain natriuretic peptide is between 0-100 pg/ml. If the patient's value is less than 100 pg/ml, heart failure can be ruled out. If the patient's value is greater than 100pg/ml, the patient's heart failure should be considered. possibility.

2. N-terminal brain natriuretic peptide precursor

N-terminal brain natriuretic peptide precursor The normal range of N-terminal brain natriuretic peptide precursor varies according to the age of the patient. If the patient is less than 50 years old, the normal value is below 450pg/ml; the N-terminal brain natriuretic peptide precursor of the population aged 50 - 75 is below 900pg/ml

; Ejection fraction The normal value

of ejection

fraction is usually between 50 and 70%. If the patient is below 50%, it is usually caused by abnormal cardiac function.
