[Dynamics of the strength of the rat left ventricle wall in experimental uncomplicated myocardial infarction].
Left ventricular wall stability was studied in 131 normal rats at different terms of uncomplicated experimental myocardial infarction. Left ventricular wall stability was estimated by the normal effort required for its destruction. Normal left ventricular wall could stand the pressure of 1.1 X 10(5) Pa. During ischemic phase of myocardial infarction the wall stability in the infarction area increased up to 1.5 X 10(5) Pa. It diminished during necrotic phase, however timely started repair processes did not let it drop lower than 1.0 X 10(5) Pa. The mechanisms of preserving ventricular wall stability in the infarction area were studied in detail.
