A specific feature of the diagnosis of primary arterial hypertension in elderly patients

Objective  – the analysis of a group of factors, leading to the increase of pulse pressure in the direction from aorta to microcirculation vessels, in order to define the diagnostic criterion for exception of primary arterial hypertension. Material and methods.  In the study, the modelling of the functions of arteries in cardiovascular system was used. Results.  The role of the increase of pulse pressure to the periphery of blood circulation was regarded as the diagnostic attribute of exception of the primary arterial hypertension. It was noted, that physical factors of the increase of pulse pressure to the periphery of blood circulation were insignificant. The cardiovascular reflex has the major influence on the increase of pulse pressure, its deterioration results in the decrease of this pressure. Conclusion.  The analysis revealed the fact, that the normal ankle-brachial index allows for exclusion of primary arterial hypertension in a patient, even if the absolute values of arterial pressure are in the limits corresponding to this disease.
