A group was formed of patients presenting with electrical instability of myocardium (those persons manifesting induction of ventricular tachicardia, ventricular fibrillation) after performing programmed stimulation of ventricles of the heart in 63 patients suffering from myocardial infarction and unstable angina pectoris. The main noninvasive markers of electrical instability were shown to be postinfarction cardiosclerosis, circulatory insufficiency, evolution of acute aneurysm of the heart. Institution of differentiated therapy involving correction of circulatory insufficiency with capoten, low doses of beta-blockers, specified use of antiarrhythmic drugs tailored to the individual, employing electrophysiologic testing, make it possible to improve the intrahospital diagnosis in myocardial infarction and select a group of patients to be surgically tested.

[Lipid metabolic changes in the lung tissue of patients dying in the acute period of a myocardial infarct]. / Izmeneniia lipidnogo obmena tkani legkikh bol'nykh, umershikh v ostrom periode infarkta miokarda.

Fatty-acid composition of lipids was determined as was activity of lipid peroxidation and lung tissue content of neutral fats and phospholipids in myocardial infarction during the acute phase of the course of the disease using gas-chromatographic, biochemical, and morphological techniques. Lung tissue in myocardial infarction was found out to accumulate neutral fats. Also recordable in lung tissue was redistribution of phospholipids, with the interalveolar septa structures getting reduced, which fact is accompanied by changes in fatty acid composition of lipids together with activation of lipid peroxidation processes.
