[Reactions of sympatho-adrenal system in patients with ischemic heart disease during emotional stress in dependence on the personality type].

The object of the study was to show the relationship between emotional stress and excitation of the sympathoadrenal system in healthy subjects and patients with coronary heart disease (CHD). Seventy eight healthy subjects and 40 CHD patients of the II-III functional class were under medical observation. Emotional tension was simulated by two methods: arithmetic under conditions of time deficit (Krepelin counting) and work in a homeostat. Homeostat simulation of emotional tension turned to be more stressogenic than Krepelin counting. In CHD patients, increase of adrenaline and noradrenaline levels was demonstrated in the condition of the emotional tension simulation. Two personality types were distinguished as type A (leaders) and type B (subordinates). The increase in the catecholamine level was especially pronounced in CHD patients of type A (leaders).
