May support BNP as sensitive marker in porcine HF models; leaves open clinical translation and human validation.
Do secretion and circulating levels of ANP, N-terminal proANP, and BNP increase during evolving heart failure in a porcine model?
In a porcine model of pacing-induced heart failure, BNP showed a larger percentage increase compared to ANP and N-terminal proANP, suggesting its potential superiority as a marker of heart failure development.
Klinge et al. (1998) studied this question.
