ABSTRACT
In this study we used the samples of autopsy material from 15 patients who died of myocardial infarction. As control we used autopsy material from 5 victims of car accidents. Quantitative comparison of area of coronary arteries of healthy persons and patients with myocardial infarction revealed its decrease in patients with myocardial infarction. In ischemic heart disease patients there were many "xanthoma cells" forming the basis net filled with glycoproteins. Thickening of intima in patients with ischemic heart disease was due to increased quantity of glycosoaminoglycans and glycoproteins. In coronary arteries of all patients with myocardial infarction we found inflammatory infiltrates, consisting of lymphocytes and xanthomatous cells.

OBJECTIVE: To prove the involvement of the autonomic nervous system in the formation of thrombotic status of the patients. 24 patients with myocardial infarction were enrolled in the study. Catecholamines levels were compared duing pain episodes and at rest. Patients were divided in to 2 groups according to the level of norepinephrine during the pain episode: Group 1-12 persons with the level of norepinephrine more than 500 pg/ml, and group 2-12 persons with a level below 500 pg/ml. Patients in group 1 the level of beta thromboglobulin and thromboxane were elevated, as well as there are changes of cAMP and cGMP, indicating increased thrombogenic activity. Particular attention was paid to the 8 patients in Group 1, in which the level of norepinephrine is maintained above 500 pg/ml both during pain and at rest (disseminated intravascular coagulation).
