Myocardial Carbohydrate Metabolism
Myocardial metabolism of Nembutalized normal intact dogs was studied with the aid of the coronary sinus catheterization technic. Oxygen, glucose, lactate and pyruvate were extracted by the heart in direct relation to the arterial level of each substance, independently of the others. Pyruvate and lactate showed a high myocardial extraction coefficient, but the normal low arterial levels at rest ...
متن کاملMyocardial and Body Metabolism
Cellular energy substrates and metabolites, electrolytes, oxygenation, and acid-base balance, in arterial and coronary sinus blood of seven adult patients who died after valvular replacements, were studied and compared with these measurements from five patients having aortic replacement who survived. Six of the patients were in New York Heart Association class IV. All but one died within 24 hr ...
متن کاملMyocardial Energy Metabolism
The effects of fructose 1,6-bisphosphate (F-1,6-P2) on the isolated Langendorif-perfused heart were studied by monitoring flavoprotein fluorescence, oxygen consumption (MV02), coronary flow (FJ, systolic intraventricular pressure (PYS), diastolic intraventricular pressure, and contraction frequency. The cellular energy state and cytosolic pH were determined by means of 31p nuclear magnetic reso...
متن کاملExercise training has restorative potential on myocardial energy metabolism in rats with chronic heart failure
Objective(s): Exercise training is a well-known accelerator for the treatment of chronic heart failure (CHF). The current study aimed to investigate the restorative effects of aerobic interval training (AIT) intervention on myocardial energy metabolism in CHF rats. Materials and Methods: Post-myocardial infarction (MI) heart failure animal model was established. The Sprague-Dawley rats were ran...
متن کاملMyocardial metabolism of fatty acids.
The myocardium is able to utilize both carbohydrates and noncarbohydrates for the performance of its work (1). Extraction of an individual substrate is usually determined by its arterial level. Thus, after a carbohydrate meal the heart derives much of its energy from the metabolism of carbohydrates; however, in the fasting state myocardial energy production is dependent upon noncarbohydrates, p...
