So an apple is better than its juice, raw apple juice is better than cooked apple juice you buy in stores, cooked juice better than reconstituted and cooked juice and reconstituted apple juice better than some random sweet 'juice' that happens to taste like apples made in a laboratory made from bacterial excretions and so on.
Conditions associated with elevated BNP other than CHF are as follows: 1  Acute renal failure and chronic renal failure. 2  Hypertension (HTN) 3  Pulmonary diseases such as pulmonary hypertension, severe chronic obstructive pulmonary disease (COPD), pneumonia, pulmonary embolism, adult respiratory distress syndrome (ARDS)
On the other hand, a person with known heart disease, who has a BNP level >1200 most likely does have CHF. Unfortunately, cardiac diseases other than CHF can produce BNP levels between 100 and 1200. This is the reason why the specificity of BNP for CHF is only 70 to 75%.
