A new model for testing therapeutic interventions during myocardial ischemia

, : A new model for testing therapeutic interventions during myocardial ischemia. Research in Experimental Medicine. Zeitschrift für die Gesamte Experimentelle Medizin Einschliesslich Experimenteller Chirurgie 182(2): 149-152

An open-chest dog heart model is presented which shows highly reproducible hemodynamic, electrophysiologic, and metabolic changes during and after short-term coronary occlusions. We repeatedly performed 3-min coronary ligations of the proximal ramus interventricularis anterior followed by reperfusion periods of 45 min. Thus, hemodynamic, metabolic, and electrophysiologic parameters of myocardial damage were fully reversible. The experimental model presented seems well suited to evaluate interventions which aim at influencing the extent and damage of myocardial ischemia without needing a large number of separate experiments.

FDG uptake in teres minor (TM) muscle is often physiologically observed. Here we reviewed data of 578 consecutive patients; TM uptake was observed in 138 patients-in 2 of 68 patients who were administered with FDG via a preexisting line and in 136...
