METHOD OF PREDICTING COURSE OF ESSENTIAL ARTERIAL HYPERTENSION IN TEENAGERS Russian patent published in 2011 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to pediatrics, cardiology, and can be used for prediction of course of essential arterial hypertension (EAH) in teenagers. Factors influencing course of essential arterial hypertension in teenagers are determined, namely: sex - x1, gestation term for the moment of delivery - x2, genealogical anamnesis on hypertension disease - x3, AH debut - x4, bodyweight index - x5, initial vegetative tone - x6, vegetative reactivity - x7, presence of changes on fundus of eye - x8, level of sodium content in blood - x9, level of magnesium content in blood - x10, level of cortosol content in blood - x 11, level of prolactin content in blood -12, level of high-density lipoproteids content in blood - x13, level of triglicerides content in blood - x14, level of uric acid content in blood - x15, average value of systolic arterial pressure at night - x16, day index of systolic arterial pressure - x17, final diastolic diametre of left ventricle - x18, type of output from left ventricle - x19, coefficient of diastolic pressure variability in day time - x20. Factors are given numerical values, namely: risk factor x1 in case of male sex is given - 1, in case of female sex - 2, for x2 in case of urgent delivery - 0, in case of preterm delivery - 1, for x3 - in case of unburdened genealogical anamnesis on hypertension disease - 0, in case if anamnesis is burdened on father's line - 1, on mothers line - 2, on both sides - 3; for x4 - age of child when higher values of arterial pressure were first registered, for x5 - value of body weight index, for x6 in case of eutonia - 0, vagotonia - 1, sympathicotonia -2, for x7 in case of normal vegerative reactivity - 0, hypersympathicotonic - 1, asympathicotonic - 2, for x8 in case if there are no changes in fundus of eye - 0, in case if angiospasm is present -1, presence of other changes - 2, for x19 in case of normal output from left ventricle - 0, in case of hyperkinetic output - 1, for x10, x11, x12, x13, x14, x15, x16, x17, x18, x9, x20 - numerical values of said parametres. Prognostic coefficients F_1, F₂, F₃ are calculated. If F₂<F₁>F₃ - favourable version of essential arterial hypertension course is predicted in teenager and risk of essential arterial hypertension development in future is minimal. If F₁<F₂>F₃ - teenager gets into boundary group with possible development of essential arterial hypertension and it is necessary for him to start therapeutic-preventive treatment earlier. If F₁<F₃> F₂ - conclusion about unfavourable prognosis and high risk of essential arterial hypertension development in teenager in future, necessity to include them into group of higher risk with earlier beginning of hypotensive therapy is made.

EFFECT: method allows to increase accuracy of predicting course of essential arterial hypertension in teenagers.
