title: [Behavior of the night decrease of arterial pressure after suppression controlled of the antihypertensive medication].
abstract: OBJECTIVE
  The patients with hypertension who do not present a night decrease of the arterial pressure are a bigger degree of target organ damage due to the supported hypertension. In our work we analyzed after ambulatory blood pressure monitoring (ABPM) the prevalence of the condition dipper of the patients with hypertension of degree 1 and/or 2 after the suppression controlled of the antihypertensive medication; as well as the magnitude of the effect of white coat (object of another study).
  
  
  METHODS
  Almost experimental study and descriptive.
  
  
  METHODS
  Primary care. Urban health centre. Participants measurements and results. Studies of ABPM were realized in 70 essential hypertense patients with good control of the arterial pressure after pharmacological treatment before suspending the antihypertensive medication (1 phase) and to the 4 weeks of leaving the treatment (2 phase), two periods being programmed: diurnal and night.
  
  
  RESULTS
  Of all 70 hypertense patients, 18 (26%) did not manage to carry out 2 ABPM since after the retreat of the medication there presented blood pressure unacceptable values that forced to re-introduce the medicaments. The 79% of the hypertense patients were dipper after the 1 monitoring and that after the suppression of the antihypertensive medication, 83% was continuing being dipper. Depending on the gender there were no statistically significant differences as for the night decrease of the arterial pressure in both periods. Finally, 75% and 11.5% of the patients were dippers or not dippers, respectively, in both phases and only 13.5% of the patients it changed its condition.
  
  
  CONCLUSIONS
  The retreat of the medication in hypertense of degree 1 and/or 2 well controlled does not modify the patients' percentage with night decreases of the blood pressure.
