Belke, Darrell D., Terje S. Larsen, Gary D. Lopaschuk, and David L. Severson. "Glucose and fatty acid metabolism in the isolated working mouse heart." American Journal of Physiology-Regulatory, Integrative and Comparative Physiology 277, no. 4 (October 1, 1999): R1210—R1217. http://dx.doi.org/10.1152/ajpregu.1999.277.4.r1210.
Although isolated perfused mouse heart models have been developed to study mechanical function, energy substrate metabolism has not been examined despite the expectation that the metabolic rate for a heart from a small mammal should be increased. Consequently, glucose utilization (glycolysis, oxidation) and fatty acid oxidation were measured in isolated working mouse hearts perfused with radiolabeled substrates, 11 mM glucose, and either 0.4 or 1.2 mM palmitate. Heart rate, coronary flow, cardiac output, and cardiac power did not differ significantly between hearts perfused at 0.4 or 1.2 mM palmitate. Although the absolute values obtained for glycolysis and glucose oxidation and fatty acid oxidation are significantly higher than those reported for rat hearts, the pattern of substrate metabolism in mouse hearts is similar to that observed in hearts from larger mammals. The metabolism of mouse hearts can be altered by fatty acid concentration in a manner similar to that observed in larger animals; increasing palmitate concentration altered the balance of substrate metabolism to increase overall energy derived from fatty acids from 64 to 92%.

The ability of exogenous lysophosphatidylcholine (LPC) to produce electrophysiological abnormalities in cardiac tissues and cardiac arrhythmias in isolated hearts has been well documented. In this study, the arrhythmogenic nature of LPC in the rat, rabbit, and guinea pig hearts was studied. The rat heart was found to be the most susceptible to LPC-induced arrhythmias, while the guinea pig heart was the least susceptible. Perfusion with labelled LPC revealed that the severity of arrhythmias correlates well with the amount of labelled LPC found in the microsomal membrane. The biochemical basis for the differences in the accumulation of LPC in the microsomal membrane of different animal species was investigated. Our results strongly indicate that the LPC level in the microsomal membrane may be regulated by the activity of microsomal lysophospholipase.

Treatments aimed at modifying cardiac substrate utilisation are designed to improve metabolic efficiency. In the fasting state, the heart mainly relies on fatty acid oxidation for its energy production. The heart can adapt to metabolise glucose, lactate and amino acids depending on the predominate milieu and demands placed upon it. A shift from fatty acid oxidation to carbohydrate oxidation leads to a lower oxygen consumption per unit of adenosine triphosphate produced. It is this concept of improving cardiac efficiency by a reduction in oxygen demand that underpins the use of metabolic manipulating agents as a therapeutic strategy in heart failure. Cardiac energy starvation is increasingly recognised as playing a central role in the pathophysiology of heart failure. Alterations in substrate utilisation thus underlie the hope that metabolic manipulating agents will be of benefit in heart failure of both ischaemic and non-ischaemic origin. This metabolic shift is achieved by promoting glucose utilisation and reducing the utilisation of fatty acids. This leads to a greater production of adenosine triphosphate per unit of oxygen consumed. With an ongoing demand for treatment options in ischaemic heart disease and the growing burden of chronic heart failure, new treatment modalities beyond contemporary therapy warrant consideration. This thesis aims to investigate the short term effects of metabolic manipulation on changes in cardiac energetic status, cardiac function, efficiency and substrate utilisation.

Adix, Longlet Nancy J. "Chronic Ventricular Sympathectomy : Effects on Myocardial Metabolism." Thesis, University of North Texas, 1993. https://digital.library.unt.edu/ark:/67531/metadc278768/.
Chronic ventricular sympathectomy elicits changes in the coronary circulation, myocardial oxygen consumption and size of infarction resulting fromcoronary occlusion. These changes indicate a change occurring in the basic metabolism of the heart in response to the removal of its sympathetic nervous input. This hypothesis was tested using two groups of dogs, a shamoperated control and a ventricular sympathectomized group. The sympathectomy procedure was an intrapericardial surgical technique which selectively removes ventricular sympathetic input. Four weeks after surgery, left ventricular tissue samples were obtained and rapidly frozen to -80°C. Selected metabolic variables were then compared between the two groups.

Several platelet products indicating platelet activation have been detected in blood and urine of patients (PTS) with angina pectoris (AP) at rest. Platelet activation mainly depends on local changes in the morphology or biochemical behaviour of the vessels. Whether platelet hyperaggregability is of additional importance in the pathogenesis of unstable AP is up to now unclear. In a prospective trial we therefore evaluated 32 patients (PTS) with coronary heart disease, 16 with AP at rest during the last 8 hours before blood collection and 16 age and sex matched controls with stable exertional AP. Platelet aggregation was measured upon stimulation with ADP (0.5, 1 and 10 μmol/l) and collagen (1and 5μg/ml), and c-AMP was determined in platelet rich plasma before, and, as an estimate of platelet adenylate cyclase activity, after stimulation of this enzyme with PGE 1 (10 μmol/l for 30 s). For all concentrations of both ADP and collagen no significant differences in the rates and extents of aggregation could be found between the groups. Correspondingly, the mean (±. 2 SEM) concentrations of c-AMP were similar, basally (4.1 ±.1.4 pmol/ml for PTS withunstable AP and 5.3 t 1.3 pmol/ml for PTS with stable AP)and after stimulation of platelet adenylate cyclase with PGE 1 (14.8 ± 4.1 vs. 17.2 ± 2.8 pmol/ml).Conclusion: No generalized platelet hyperaggregability could be detected in our PTS with unstable AP when compared to controls with stable exertional AP.

In XIth International Congress on Thrombosis and Haemostasis. Schattauer GmbH, 1987. http://dx.doi.org/10.1055/s-0038-1643152.
Defibrotide was able to prevent the hemodynamic and biochemical alterations caused by acute myocardial ischemia (AMI) induced by coronary occlusion in the cat when infused 3.5 h before and 5 h after left anterior descending coronary artery (LAD) occlusion. In the platelet perfused heart, Defibrotide was a selective stimulator of coronary vascular PGI^ but not of platelet thromboxane formation. The present study was designed both to investigate the effects of Defibrotide injected 30 min after the induction of acute myocardial ischemia (AMI) in the cat and to evaluate the ability of this drug to reduce infarct size. In the first set of experiments a permanent ligature (5 hours) was placed around LAD. ST segment from ECG, mean aortic pressure (MAP), heart rate (HR) and the pressure-heart rate index (PRI) were considered. Plasma and tissue creatine phosphckinase activity (CFK), tissue lactate and ATP were measured by enzymatic kits from Boehringer Biochemia. 30 min after coronary occlusion a loading dose of Defibrotide (32 ng Kg-1 ) was administered i.v. immediately followed by an infusion (32 ng Kg-1 h 4.5 h-1) MAP, HR and PRI were not modified either by AMI or by the infusion of Defibrotide. AMI-ST segment increases were reduced by Defibrotide from 0.5 h after the beginning of the treatment (—49% vs. AMI control) to the and of experiments (-83% vs. AMI control after 5 h occlusion period). Plasma CFK was reduced from 2.5 h after the beginning of the treatment (-29%) till the end of experiments (-52%). Ischemic tissue CFK, lactate and ATP were normalized by Defibrotide. In the second set of experiments the animals were infused with Defibrotide (50 or 200 mg Kg-1 h-1 , i.v.) starting 2 hours before coronary ligature. The infusion was maintained throughout the 5 h occlusion period. The risk and infarct areas were measured by Evans blu and nitroblue tetrazoliun staining. The 51 ± 3% of risk area was infarcted in AMI control cats. Defibrotide at the two tested doses significantly reduced these infarct areas to 42 ± 4% and 34 ± 2% of risk areas respectively. The beneficial effects of Defibrotide observed in AMI could be attributed both to its ability to enhance PGI2 release from vascular walls and to improved local tissue oxygenation and energy supplies. However it could be taken into account a direct cytoprotective action.

The aim of this work is the development of a mathematical model which integrates a model of the human respiratory system and a model of the human thermal system. Both models were previously developed at the same laboratory, based on classical works. The human body was divided in 15 segments: head, neck, trunk, arms, forearms, hands, thighs, legs and feet. Those segments have the form of a cylinder (circular cross-section) or a parallelogram (hands and feet) with the following tissue layers: muscle, fat, skin, bone, brain, lung, heart and viscera. Two different geometries are used to model the transport of mass and heat in the tissues. For the mass transfer, those layers are considered as tissue compartments. For the heat transfer, the body geometry is taken into account. Each segment contains an arterial and a venous compartment, representing the large vessels. The blood in the small vessels are considered together with the tissues. The gases are transported by the blood dissolved and chemically reacted. Metabolism takes place in the tissues, where oxygen is consumed generating carbon dioxide and heat. In the lungs, mass transfer happens by diffusion between an alveolar compartment and several pulmonary capillaries compartments. The skin exchanges heat with the environment by convection, radiation and evaporation. The differential transport equations were obtained by heat and mass balances. The discretization heat equations were obtained applying the finite volume method. The regulation mechanisms were considered as model inputs. The results show three different environment situations. It was concluded that the gas transport is most influenced by the temperature effects on the blood dissociation curves and the metabolism rise in a cold environment by shivering.
