[Circadian rhythm of cortisol secretion in the acute stage of myocardial infarction].

Patients with macrofocal and transmural acute myocardial infarction (AMI) are reported to have statistically significant rhythms of cortisol secretion though there are cases of dysrhythmia. Circadian rhythms of cortisol secretion are typical for relatively light AMI course while a severe clinical run gives rise to dysrhythmia in the form of infradian neorhythmostasis or dysrhythmostasis of cortisol activity.
