BACKGROUND/AIMS This study aimed to identify the signaling pathway for the proposed link between phosphodiesterase-5A (PDE5A) inhibition and decreased cardiac Na(+)/H(+) exchanger (NHE-1) activity. METHODS NHE-1 activity was assessed in rat isolated papillary muscles by the Na(+)-dependent initial pH(i) recovery from a sustained acidosis (ammonium(More)
