[Clinico-hemodynamic correlations in patients with a postinfarct aneurysm of the left ventricle].
Eighty-four patients with left-ventricular post-infarction aneurysm were examined, 74 of those showing clinical signs of circulatory insufficiency. Selective coronarography and left roentgenocinematoventriculography were performed in all cases. Volumetric parameters and the ejection fraction were estimated for the total and contractile segment of the left ventricle. Statistical treatment of the data thus obtained demonstrated a relationship between the segmental contractility and manifestation of clinical signs of circulatory insufficiency. The limits were established for increments in residual and end-diastolic volumes that lead to the development of clinical manifestations of circulatory insufficiency. An increased end-diastolic pressure seems to be indicative of reduced elasticity (pliancy) of the left-ventricular myocardium, as reflected in markedly disturbed segmental contractility of the left-ventricular wall.
