SOME NEUROHUMORAL SYSTEM IN PATIENTS WITH CORONARY HEART-DISEASE AND IN EMOTIONAL PAIN STRESS - MODES OF THEIR PHARMACOLOGICAL REGULATION

The sympathicoadrenal and kallikrein-kinin systems were studied in 225 patients with various coronary heart diseases before and after therap y with lipoic acid (150 mg/day), tocopherol (100 mg/day), anaprilin (4 0 mg/day), prodectin (750 mg/day) or their combination. Myocardial and adrenal catecholamine levels were measured in experiments on animals exposed to emotional pain stress. Their levels were found to be affect ed by lipoic acid, tocopherol, obsidan or their combinations in the sa me doses, taking into account species specificity. Lipoic acid therapy for patients with coronary heart disease decreased epinephrine excret ion, enhanced the elimination of vanillylmandelic acid and norepinephr ine. Tocopherol lowered daily urinary epinephrine levels and increased the release of vanillylmandelic acid, without changing epinephrine ex cretion. Emotional pain stress resulted in myocardial epinephrine accu mulation and adrenal norepinephrine in the animals. Lipoic acid preven ted this accumulation, whereas tocopherol did not possess this effect.
