[Temporal evolution of neuro-endocrine secretions in reaction to various stressors in coronary and non-coronary subjects (author's transl)].
The purpose of this study is a comparison of sequential physiolocical reactions to different stressors in 21 post-myocardial infarction and 21 non-coronary subjects. Two stressful situations are induced in a timespan of 2 hours; the first stress is catheterization, the second is a film implementing either a focused or a diffuse anxiety. Throughout the experiment, the following physiological parameters are assessed six times consecutively: levels of catecholamines, cortisol, TSH, insulin and the ratios: adrenalin/fnor-adrenalin and adrenalin/cortisol. Results indicate that levels of adrenalin and cortisol show specific variations with time and are most sensitive to catheterization. Levels of nor-adrenalin very differently with time among coronary patients, as well as they do in normal subjects. Individuals submitted to focused anxiety show increased levels of catecholamines and cotisol, as well as a lower level of insulin than subjects submitted to diffuse anxiety. The sequential evolution of cortisol differs in coronary patients and normal subjects and in function of the type of film attended. Physiological reactions to stress and far more specific and interdependent than prior studies stated in the past. They vary with the degree and the nature of stress. It is our belief that there is no standardised response to stress.
