A Hipertenso Arterial Sistmica (HAS) is characterized as a chronic, generally assintomtica pathology, being responsible direct and indirectly for the morbidade and mortality of the Brazilian population. The Health department defined values (figure 1) as limit to define the HA, being been considered hipertenso the individual that to present the 140/90 value equal or bigger mmHg, adding that this value must be found in at least two gaugings carried through at different moments, in individual that does not make anti-hipertensiva medication use (ENRIQUE et al., 2008). The increase of the arterial pressure occurs when the relation between cardiac debit and the total peripheral resistance are modified, being, in fact, a complex characteristic determined by the integration of multiple genetic, ambient and demographic factors (VALDOMIRO; BERTONCIN; FRANCISCO, 2008). ADULTS (BIGGER OF 18 YEARS) Arterial Pressure (mmHg) SistlicDiastlicCategoria Severe 110Hipertenso (period of training 3) > ou=210> very severe ou=120Hipertenso > 140 beyond meaning a cost of 475 million real expenses with 1,1 million internments per year (ZAITUNE et al., 2006). They is esteem that 40% of enceflicos vascular accidents and 25% of the infartos occurred in hipertensos patients could be prevented with appropriate anti-hipertensiva therapy.
