A BNP test is a blood test that is used to check a person's B-type natriuretic peptide levels, which are associated with heart...
The BNP or NT-proBNP test may be performed using a blood sample taken from a vein in your arm during a process called venipuncture. In this procedure, a health professional will cleanse the puncture area with an antiseptic wipe and then insert a small needle into your vein. The needle is...

For comparison between groups, the log-rank test was used. Hazard ratio (HR) was derived from univariate Cox regression and tested for independence from baseline characteristics using multivariate Cox regression entering all variables. Interactions between intervention and patient characteristics were ...

(cardiomyocytes). BNP plays a crucial role in the regulation of blood pressure and fluid balance. When the heart is stressed, such as in cases of heart failure, the body releases more BNP to help the heart function by promoting vasodilation, reducing blood volume, and decreasing...
At a blood concentration of 80 pg/mL, BNP was an accurate predictor of the presence of CHF (95%); measurements less than this had a high negative predictive value (98%). The measurement of BNP appears to be a sensitive and specific test to diagnose CHF in urgent care settings. The ...
