Intravenous iron delivers a sustained (8-week) lowering of pulmonary artery pressure during exercise in healthy older humans.

were unable to show similar changes at low and high (4559 m) altitude in adults known to have particularly vigorous hypoxic pulmonary vasoconstriction, but did find that dexamethasone increased V ̇ O 2 m a x significantly, a rise that was associated with a strong trend toward an increase in peak work rate and a lower pulmonary artery pressure (Fischler et al. 2009 ).
