[Basic hemodynamic and vegetative regulatory indices in adolescents-healthy and sick with arterial hypertension].

Basic hemodynamic indices in aged 15-16 practically healthy adolescents do not differ essentially, but in patients with juvenile arterial hypertension is noticed their authentic rise in proper age groups. The correlation of body mass is marked with the basic hemodynamic parameters and likewise the indices of double production depend on systolic pressure and heart rate. In adolescents troubled with juvenile arterial hypertension is noticed intensification of sympathetic link of regulatory mechanisms of vegetative nervous system and unsatisfactory hypersympathetic reaction on orthostatic test which shows the total disbalance of the organism. The latter can be considered as one of the pathologic aspects of development of juvenile arterial hypertension; on the other hand non-invasitive investigation of functional state of vegetative nervous system maybe recommended for inclusion in the project of preventive medical practice to early revealing juvenile arterial hypertension or its predisposition to it.

[Clinical characteristics of juvenile systemic hypertension in the population of Tbilisi].

The goal of the work was to study a prevalence of juvenile systemic hypertension among 15-16 years old adolescents of Tbilisi, its clinical characteristics and several indices of mental capacity. In the result of an analysis of 378 adolescents' blood pressure records only 6 (1.6%) had high normal values and 32 (8,46%) revealed juvenile systemic hypertension. Four youths from 6 with high normal values refused to participate in a further investigation. For this reason the study was continued only in 32 youths with juvenile systemic hypertension. In the contingent noted 6 (18,75%) had overweight, 9 (28,12%) had hereditary predisposition, 15 (46,9%) revealed excessive use of salt, 3 (9,4%) had moderate consumption of alcohol and 7 (21,9%) noted insufficient physical activity. Juvenile systemic hypertension in youth was predominantly asymptomatic, only 9 (28,12%) had mild headache in the evening, 12 (37,5%) had light fatigue and 5 (15,6%) weak dizziness. Fourteen youths noted diminished work-status and being behind in learning process. In the persons with juvenile systemic hypertension diminution of the attention concentration was observed during a fulfilment of a simple sensor and motor task in condition of monotonous work (increment of answers missed up to 13+/-12%). A psycho-emotional loading test has proved the fact of mental capacity lowering within the persons with juvenile systemic hypertension that is expressed in the increment of errors made up to 12+/-3,1% and answers missed up to 11+/-2,3%. Our investigations confirm the reasonability of blood pressure monitoring among adolescents for the early detection of the juvenile systemic hypertension and the conduction of an opportune preventive measures for avoiding of cardiovascular diseases in a mature age.
