ACE Inhibitors Promote Nitric Oxide Accumulation to Modulate Myocardial Oxygen Consumption

Abstract

Our data indicate that stimulation of local kinin formation by use of a precursor for kinin formation or inhibition of kinin degradation by use of ACE inhibitors increases NO formation and is important in the control of cardiac O2 consumption. Vasodilation and control of myocardial O2 consumption by NO may contribute importantly to the therapeutic actions of ACE inhibitors in cardiac disease states.
