[Use of neural networks for prognosis of outcomes of operations for ischemic heart disease]. / Ispol'zovanie neironnykh setei dlia prognozirovaniia iskhodov operativnykh vmeshatel'stv po povodu ishemicheskoi bolezni serdtsa.

Using a mathematical model of artificial neuronal network the authors have determined the main significant factors for prognosis of the development of acute myocardial insufficiency during aorto-coronary shunting.

Operations for ischemic heart disease complicated by the appearance of postinfarction left ventricular aneurysm were fulfilled on 94 patients. The modified operation after V. Dor used in 55 patients allowed fulfilling interventions on the damaged parts of the interventricular septum excluding the application of foreign patches. Intrahospital lethality was 7.6%.

[A postinfarct heart aneurysm: its removal or revascularization?]. / Postinfarktnaia anevrizma serdtsa: ustranenie ili revaskuliarizatsiia?

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.
