title: Comparative assessment of heart remodeling in rats after experimental coronary stenosis and cryodestruction.
abstract: Comparative analysis of myocardial changes due to heart remodeling after experimental coronary stenosis and cryodestruction in rats was performed. Similar picture of heart remodeling was observed in all animals on day 45 irrespective of the type of destruction: hypertrophy of intact myocardium of the left ventricle, formation of extensive connective tissue cicatrix, and similar structural changes in the myocardium adjacent to the damage area. The type of the damaging influence possibly plays a role at the stage of lesion formation. We concluded that the proposed method of cryodestruction induces heart remodeling comparable to that observed after coronary occlusion.
