Myocardial protection of warm cardioplegic induction on the isolated perfused rat heart model.
Myocardial protection through different cardioplegia approaches is an important issue for successful cardiovascular surgery. The objective of this prospective randomized study was to evaluate the effect of myocardial protection of warm (37 degrees C) and cold (6 degrees C) cardioplegic induction, respectively, using a Langendorff isolated rat heart perfusion model. Twenty-eight isolated rat hea...
متن کاملMyocardial protection of warm blood cardioplegic induction during cardiopulmonary bypass.
In his prospective randomized clinical study, we evaluated the myocardial protection of warm blood cardioplegic induction and cold blood cardioplegic induction, respectively, during cardiopulmonary bypass. Twenty-eight adult patients who underwent valve replacement were randomly divided into two groups: group T (14 cases) received cold (6-8 degrees C) blood cardioplegic induction after ECG show...
متن کاملEFFECT OF CYANIDE IN CARDIOPLEGIC SOLUTION ON ISOLATED RAT HEART FUNCTION
It has been known that cardiomyocytes possess a remarkable ability to downregulate their energy expenditure on restricted 02 supply. However it has also been speculated that an ability to suppress aerobic respiration and ATP utilization could be a protective response to prolonged hypoxia. Having the role of the cytochrome oxidase enzyme in mind, one can ask if its inhibition by using cyani...
متن کاملSodium alterations in isolated rat heart during cardioplegic arrest.
Triple-quantum-filtered (TQF) Na nuclear magnetic resonance (NMR) without chemical shift reagent is used to investigate Na derangement in isolated crystalloid perfused rat hearts during St. Thomas cardioplegic (CP) arrest. The extracellular Na contribution to the NMR TQF signal of a rat heart is found to be 73 +/- 5%, as determined by wash-out experiments at different moments of ischemia and re...
متن کاملTemperature threshold and modulation of energy metabolism in the cardioplegic arrested rabbit heart.
Hypothermia protects ischemic tissues by reducing ATP utilization and accumulation of harmful metabolites. However, it also reduces ATP production, which might cause deterioration in the energy supply/demand ratio. Modulation of energy supply/demand according to temperature has not been previously studied in detail. In this study, isolated, perfused rabbit hearts (n = 60) were used to determine...
