title: [Control of arterial pressure: experience at a hospital monographic unit arterial hypertension].
abstract: OBJECTIVE
  To analyse the evolution of blood pressure control in patients referred to our centre for study, proportion of controlled hypertensive patients, changes in the characteristics of hypertensive patients and in therapeutic guidelines in the last twenty years.
  
  
  METHODS
  A total of 4,103 patients were referred to study of hypertension. The analysed variables year by year included sex, age, weight, systolic blood pressure (SBP) and diastolic blood pressure (DBP). Cross sections at five-year intervals were performed to collect basal SBP and DBP and the evolution of BP in the following five years.
  
  
  RESULTS
  From 1977 to 1997 the following changes were observed: basal mean age changed from 67 +/- 9 down to 56 +/- 10 years among males and from 68 +/- 8 down to 52 +/- 9 years among females; basal mean weight changed from 71 +/- 7 up to 81 +/- 8 kg among males and from 69 +/- 12 up to 73 +/- 13 years among females. Males showed a decrease in basal mean values of SBP/DBP from 176 +/- 25/112 +/- 20 mmHg down to 154 +/- 21/94 +/- 12 mmHg. In women, the corresponding values changed from 182 +/- 36/105 +/- 19 mmHg down to and 154 +/- 23/93 +/- 12 mmHg. In the early 1980's, 62% of patients received one or no antihypertensive drug. In the last few years such percentage has been 36% and 64% have been treated with two or more drugs.
  
  
  CONCLUSIONS
  A decrease in age and an increase in weight of hypertensive patients referred to study have been observed in the last twenty years. Such patients show a less severe hypertension compared with referred patients in the early years. The use of new hypertensive drugs and their combined use are measures that contribute to improve the percentage of controlled hypertensive patients.
