My bnp level is 319. is this considered serious or some kind of trend later in life for chf?

Elevated BNP: A bnp greater than 500 is a positive predictor of congestive heart failure. Between 100 and 500 we must consider left or right ventricular dysfunction, or kidney insufficiency. It may also be elevated in lung disease, including acute pulmonary embolism.

BNP: Bnp=brain natriuretic peptide , is a neuro hormone produced by heart ventricles. It is diagnostic ; prognostic marker. Your 319 means you have mild heart failure;can get worse. Bnp<100 means no heart failure;100-300;above CHF present and not COPD as cause of wheezing ; breathlessness. 301to600=mild; 601to900=moderate; >901=severe chf. Please avoid alcohol. Bnp is also for treatment of chf.

BNP: Good question. Bnp has may causes like kidney failure, increase pressure in the lungs and many other. Bnp level doesn't predict who will go into heart failure.
