[Various indicators of the kinin and sympathico-adrenal systems in patients with recurrent myocardial infarct].

The interrelationship between the kinin and sympathoadrenal systems of blood was studied in 45 patients with repeated myocardial infarctions of different clinical course. Complicated repeated infarctions with rhythm disorders, cardiac asthma, pulmonary oedema, cardiogenic shock were accompanied by a more distinct elevation of the blood catecholamines level and the kinin system activity, than the non-complicated ones. The changes in the activity of the kinin and sympathoadrenal systems were found to parallel each other. Some diagnostic and more promising prognostic importance of the determined parameters was revealed.
