Hypertension (HTN) Pulmonary diseases such as pulmonary hypertension, severe chronic obstructive pulmonary disease (COPD), pneumonia, pulmonary embolism, adult respiratory distress syndrome (ARDS)
What is a normal BNP level?
Experts agree that there is a healthy range for BNP levels. The cut-off point can vary by laboratory, but commonly, the healthy range is less than 100 picograms of BNP per milliliter (pg/ml) of blood. This means that a result of more than 100 pg/ml indicates the possibility of heart failure.
Why would a doctor order a BNP?
Why Is a BNP Blood Test Needed? BNP levels help your doctor figure out if you have heart failure or something else that has similar symptoms such as shortness of breath. The test also shows if your heart failure has worsened. It’ll help your doctor decide what treatments you need and if you need to be hospitalized.
How long do people live with heart failure?
