GONZALEZ ALONSO, N. et al. Do we control our hypertensive patients better than five years ago?. Medifam [online]. 2001, vol.11, n.9, pp.54-59. ISSN 1131-5768.

Setting: urban Health Centre.  Subjects: diagnosed patients of hypertension in three Primary Health Care surgeries.  Objectives: to know the degree of control of hypertensive patients in 1995 and the actual moment, and the treatment used.  Design: cross-sectional descriptive in 1995 and 2000.  Interventions: through clinic hystory were taken social demographics dates, personal antecedents and associated disease, and blood pressure and treatment, in 1995 and the actual moment. All dates were incorporated to a data base "r-sigma", using tools of descriptive and analytical statistics.  Results: there were 456 hypertensive patients (approximately 80% were under 65 years and 2/3 women). The mean blood pressure in 1995 and 2000 were of systolic blood pressure (SBP) (144.62 vs 141.69, p<0.05, t=2.29) and dyastolic blood pressure (DBP) (82.06 vs 80.48, p<0.001, t=3.475). In reference to the blood pressure control, in 1995 and 2000, following the OMS criteria, was: "optimum"(2.1% in 1995 vs 3.5% in 2000), "normal"(6.2 vs 11.5%), "normal-high"(27.3 vs 27.9%), "HT-1"(47.1 vs 49.5%), "HT-2"(15.3 vs 6.9%) and "HT-3"(2.1 vs 0.7%); dates with statistically significants differences (χ₅² =3.828 p<0.001).  In 1995 the porcentage of patiens with normal rates of blood pressure were 35.54% and in the actual moment 43.02% (χ²= 4.158, p<0.05). The treatment followed in 1995 and 2000 was dietetic (19.6 vs 13.3%), monotherapy (50.4 vs 51.66%) and association (29.91 vs 35.03%), χ₂² = 6.482, p<0.05. Pharmacological groups more used in both cases were ACEI, tiacides and calcium blockers. It were founded in 2000, an increase in using ARA-II and beta-blockers.  Conclusions: the blood pressure control have improved respects to 1995, perhaps in relation with more aggressive treatment (increase of using drugs and associations). We have found a change in pharmacological perfil used.
