标题：Psychophysiological mechanisms of mental stress reactions in patients with “hypertension at work” and patients with essential hypertension: a comparative analysis.
摘要：In the study, psychological and physiological features were assessed during an experimentallydesigned stressful situation in 85 subjects with hypertension (HTN) in theworkplace, 85 patients with essential HTN, and 82 healthy individuals.It was showed, that patients with HTN in the experimental situation were characterizedby a complex of physiological and psychological features, which distinguish themfrom healthy participants. A reliably greater increase In systolic blood pressure (BP) wasrecorded in these patients in comparison with healthy individuals (on average by 14 and3 mmHg respectively). The aspiration level (AL) of these patients was characterized by areliably greater height, inadequacy, and instability; as for nonverbal behavior, it revealeda reliably greater amount of gestures, and frequent changes in voice tone against similarfeatures of healthy individuals.The group of patients with HTN at work, when compared with essential HTN patients,was characterized by a reliably greater increase of systolic BP (on the average by16 and 4 mmHg respectively) as a reaction to emotional stress. The systolic BP increasein this group was revealed in combination with an initially reliably lower catecholamines’level (CA), a gradual decrease of CA level in urine, and renin and angiotensin-1 in bloodplasma during the experiment. This combination is an indicator of chronic stress andpsychophysiological exhaustion. The patients did not manifest any increase of anxietyduring the experiment; they were characterized, however, by a greater frequency of ALinadequacy and instability. The behavior of patients with HTN at work during the experimentwas marked by a limited repertory of poses and gestures, but more vigorousfacial expressions, and frequent pitch jumps. Obtained results lead us to confirm thatthe repression of emotions comes as a significant pathogenetic factor in the genesis ofpsychosomatic syndrome among patients with HTN at work, as opposed to patients withessential HTN.
