[Levels of B-endorphin in patients with silent myocardial ischemia].
Plasma beta-endorphin levels were estimated in patients with painless myocardial ischaemia. The survey was made in 90 patients with coronary artery disease: 55 of them after myocardial infarction and 35 with chronic stable angina pectoris. The control group comprised 22 healthy persons. Plasma beta-endorphin level was determined in all examined patients immediately before the exercise test, just after finishing exercise test, and 6 minutes after the termination of the exercise test. Beta-endorphin plasma levels has been determined with a radioimmunologic method by the means of "beta-endorphins [125J]RIA Kit" manufactured in NEN Research Products. Study showed that in the patients with silent myocardial ischaemia plasma beta-endorphin level was higher than in patients with painful myocardial ischaemia both at rest during exercise test. Increase of plasma beta-endorphin in examined patients can be one of etiopathogenetic factors of silent myocardial ischaemia.
