Representative isometric tension recordings show modest effects of L-cysteine (n=3) (A) and NaHS (n=3) (B) on tension of isolated coronary artery rings pre-constricted with U46619. In-vivo intracoronary infusion of L-cysteine had no effect on basal coronary blood flow (C) while intracoronary infusion of NaHS significantly augmented coronary flow at plasma concentrations >300 µM (D).
