Overview
The measurement of blood pressure (BP) with sphygmomanometer cuff in the physician’s office remains as basal method, however there are pressure differences in the arterial system. Central BP in great arteries directly infl uencing the cerebral and coronary circulation may be different from BP measured over the brachial artery. In clinical praxis we dispose on noninvasive, proved and easily applicable equipment for estimation of central pressure, recording pulse waves over carotic or radial artery (so-called aplanation tonometry), or we only estimate elastic qualities of vessel wall by evaluation of pulse wave velocity. Various groups of antihypertensive drugs have different effect upon arterial compliance and through it upon central BP even when they infl uence the peripheral BP in the same way. So far we do not know if the parameters of central BP would substitute in the future the values of peripheral pressure from brachial artery and this question is the subject of further research.
Key words:
hypertension – properties of the arterial wall – blood pressure measurement
