  • Title: [Myocardial carbohydrate metabolism in limited coronary blood flow].
    Author: Likhtenshteĭn IE.
    Journal: Kardiologiia; 1981 Jun; 21(6):97-100. PubMed ID: 6267347.
    Abstract:
    Dosaged restriction of coronary blood flow (by 30, 50, 70 and 90%) was reproduced for 30 minutes in dogs with a closed chest. In all degrees of coronary blood flow restriction the loss of glycogen, accumulation of lactic acid and cAMP (in reduction of blood flow by 50 and 70%) and activation of glycogenolysis, phosphorylase and phosphofructokinase were recorded in the zone of ischemia. The changes advanced with the deepening of ischemia. Similar, though less pronounced changes were found outside the ischemic zone. Marked metabolic shifts were disclosed in the right ventricle. The mechanisms of anaerobic oxidation activation in ischemia are discussed.
