Within-person variability of BNP

In this prospective cohort of 131 patients with stable CHF, 6 BNP measurements were obtained every 4 weeks to determine BNP variability in the setting of stable CHF signs and symptoms (abstract). They found the BNP could triple or fall by a third, with no clinical change in the patient. This gives caution to using BNP as a sole variable in determining the severity of clinical CHF.
