title: [Indices of the energy processes in the myocardium in measured limitation of the coronary blood flow].
abstract: Oxidative phosphorylation, the content of creatine phosphate and inorganic phosphorus and the activity of some mitochondrial respiratory enzymes, creatine phosphokinase and Mg-dependent ATP-ase were studied in experiments on 54 dogs with dosed restriction of coronary blood flow in different parts of the heart. It was established that restriction of coronary blood flow in the circumflex branch of the left coronary artery by 30 and and 50% for 30 minutes is attended by a mild decrease in the intensity of oxidative processes, the level of creatine phosphate and cytochrome oxidase activity. The right cardiac ventricle reacts to short-term and partial decrease in coronary blood flow; all stages of energy metabolism are activated here.
