Nitric oxide (NO) is involved in the control of myocardial metabolism. In normoperfused myocardium, NO synthase inhibition shifts myocardial metabolism from free fatty acid (FFA) toward carbohydrate utilization. Ischemic myocardium is characterized by a similar shift toward preferential carbohydrate utilization, although NO synthesis is increased. The importance of NO for myocardial metabolism ...
