NT-proBNP responses. Circulating NT-proBNP concentration (A) before hypoxia (0 min), repeatedly during 60 min of hypoxic exposure, and 2 and 24 hours after the exposure. In panel B mean per cent change in NT-proBNP of two divergent groups (n=5 in both groups) are presented, which showed either increase (“upregulators”) or reduction (“downregulators”) from baseline to 24 hours of hypoxic exposure in NT-proBNP concentration.
