[Features of changes in volume-impedance hemodynamic indicators during the tilt test in young males with a history of vasovagal syncopes].

Background: The direction of changes in hemodynamic parameters during the tilt test (TT) nin individuals with history of vasovagal syncope (VVS) is a subject of discussion.

Objective: to study changes of volume-impedance hemodynamic indicators in the process of tilt test in somatically healthy young men with history of VVS.

Materials And Methods: A total of 102 men aged 18-30 years were divided into 4 groups, taking into account the specific features of fainting history and response to TT.

[Left ventricular hypertrophy as a marker of adverse cardiovascular risk in persons of various age groups].

The paper considers modern conceptions about the prognostic value of left ventricular hypertrophy (LVH) different types. The role of interaction of demographic, hemodynamic, regulatory, intracardiac factors in the formation of prognostic peculiarities in patients with different types of LVH is marked. The data of own investigations indicating that the left ventricular myocardial mass has not less important value in long-term general prognostication than belonging to a concentric or eccentric LVH type in elderly patients with hypertension are presented.
