Early diagnosis of increased stiffness of great vessels in adolescents with functional pathology of vegetative genesis

40 adolescents aged 15–17 years with functional cardiovascular pathology of vegetative origin underwent a 24-hour blood pressure monitoring (using the oscillometric method BPLabVasotens, Peter Telegin LLC, Nizhny Novgorod) with an assessment of central blood pressure parameters and rigidity of the main arteries.The scientists found significantly higher values of central systolic pressure during the day and night hours in the group of adolescents with arterial hypertension (n=13) compared to adolescents with normal blood pressure (n=27). They determined significantly higher values of the pulse wave velocity both during 24 hours and in the day and night hours in the group with arterial hypertension compared to the group of adolescents with normal blood pressure. No differences were found in the parameters of the propagation time of the reflected pulse wave and the augmentation index. The time of the reflected pulse wave propagation was significantly lower at nighttime compared to the daytime. In the group with arterial hypertension, the rate of pulse wave propagation in the aorta correlated only with the values of diastolic pressure over 24 hours and diastolic pressure in the daytime. In the adolescents with normal blood pressure, the pulse wave velocity correlated with systolic and pulse blood pressure. The augmentation index in the group of adolescents with arterial hypertension correlated with diastolic pressure, in contrast to the group of adolescents with normal blood pressure, where such a correlation was not detected.
