The circadian rhythms of myoglobin concentrations in the blood serum in acute myocardial infarct and unstable stenocardia

: Patients with acute myocardial infarction and unstable angina pectoris do not demonstrate circadian time organization of myoglobin concentration rhythms. The predominance of ultraradian and infraradian neorhthmostasis is typical of such patients. Determination of myoglobin concentration rhythms in the given patients' group may be helpful in the measurement of the size of the focus of necrosis and prediction of the course and outcome of the diseases under consideration.
