[[Criteria and clinical significance of echographic patterns of the left ventriculus anomalous deformity].]

Abstract

With the aim of the clinical significance studying of the abnormal myocardial deforma- tion (MD) patterns in left ventricle (LV) there were examined 45 patients, in whom oper- ative myocardial revascularization was performed for an ischemic heart disease. Also 31 volunteers were examined. Postsystolic myocardial contruction (PMC) of the LV, depending on its mechanism, was classified: in absence of the affection - PMC-0, in presence of myocardial ischemia - PMC-1, in loss of contractility - PMC-2a, in loss of elasticity - PMC-2b. There were depicted PMC, occurring due to overloading by pressure, delay in a free LV wall activation, protosystolic and intrasystolic delay of myocardial contruction of obscure origin. PMC-1 in the ischemic heart disease was revealed in the LV segments affected only, PMC-2 - in presence of LV aneurysm only. Appearance of PMC-1 constitutes a criterion of the myocardial function restoration. The PMC-2 severity lowering had witnessed improvement of the patients clinical state. The contraction delay of obscure origin may not be considered a criterion of the LV myocardium state.
