[A postinfarct heart aneurysm: its removal or revascularization?].
A conclusion about the hemodynamic significance of aneurysm having the area of more than 30% of the left ventricle surface is made on the basis of an analysis of the pre- and post-operative parameters of the myocardium contractility and hemodynamic indices in 49 patients with postinfarction aneurysm of the left ventricle (main group) and 26 patients with ischemic heart disease without this complication (control group). Formation of the syndrome of chronic insufficiency of blood circulation in hemodynamically insignificant aneurysm results from ischemia of the myocardium, rather than the aneurysm as such. Improvement of blood supply to the myocardium as a result of its revascularization in such patients led to normalization of the left ventricle geometry.
