A study is presented of the blood plasma level of opioid peptides in patients with progressive stenocardia. Results indicate non-homogeneity of the patients concerning the content of neuropeptides. Two subgroups were singled out: 1. patients with progressive stenocardia of exertion in which beta-endorphin and leucin-enkephalin were above normal; 2. patients with a severe course of ischemic heart disease. Here the content of same peptides was lower than in the compared group. Similar dependence of changes of the content of methionine-enkephalin was not revealed.
