Physiological, biochemical, and morphological characteristics of myocardial anoxia: the use of a semi-perfusion canine preparation.
Regional myocardial anoxia was produced in dogs by perfusion of the left circumflex artery (LCA) with deoxygenated blood. Isolated sarcoplasmic reticulum fragments (cardiac relaxing system) showed decreased Ca2+ binding and uptake. The ability of isolated mitochondria to utilise long-chain fatty acids was markedly reduced. This model has revealed inherent biochemical differences between ischaemia and anoxia.
