متن کاملFueling the hypertrophied heart.
Substrate utilization by heart muscle provides the fuel for both maintenance of structure and function of the myocardium and for ample reserve capacity to meet sudden surges in cardiac energy requirements. Many factors influence the balance of substrate uptake by the myocardium, but in general, utilization of lipids versus carbohydrates correlates to their concentration in the arterial blood. T...
