[Importance of determination of the content of lactate dehydrogenase and its isoenzymes in patients with myocardial infarct complicated by rupture of the heart].
In 18 patients with myocardial infarction. who had died due to the rupture of the heart muscle the activity of lactate-dehydrogenase (LDG) and of its isoenzymes in the blood serum and cardiac tissue was studied. Comparisons were made with the results of investigations in donors, in persons dead as a result of accidents, in patients with uncomplicated transmural myocardial infarction, with aneurysm of the heart, severe cardiogenic shock and with other lethal complications of myocardial infarction. The highest levels of the blood LDG activity were registered in cases involving rupture of the heart. The determination of the LDG and its isoenzymes activity mat be used in assessing the degree of the resorption-necrotic syndrome intensity and of factors indicating the risk of a developing aneurysm and rupture of the heart in patients with myocardial infarction.
