Abstract
Phosphodiesterase, a ubiquitous enzyme in biologic systems, functions to terminate the actions of cyclic 3′,5′-nucleotides (i.e., cyclic AMP) by catalyzing its hydrolysis (1,2). Phosphodiesterase enzymes in the cardiovascular system have different substrate specificities, kinetic characteristics, and responses to pharmacologic agents that inhibit phosphodiesterases (1,2). Aminophylline, the phosphodiesterase inhibitor most clinicians are familiar with, has other effects that include interfering with adenosine metabolism. The newer cyclic AMP specific phosphodiesterase (PDE) inhibitors (also called Fraction III or low-Km cyclic AMP) are nonsympathomimetic agents that can produce both positive inotropic effects and vasodilation independent of β1-adrenergic receptor stimulation (1,2).
