[Behavior of the night decrease of arterial pressure after suppression controlled of the antihypertensive medication].

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). DESIGN: Almost experimental study and descriptive. SETTING: 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.

[Validation of two systems of self-measurement of blood pressure, the OMRON HEM-705 CP and OMRON M1 (HEM 422C2-E) models].

Objective. To validate two monitors on the market for self-measurement of blood pressure (SMBP), an automatic one (OMRON HEM-705 CP) and a semi-automatic one (OMRON M1).Design. Descriptive study of validation of diagnostic tests.Setting. Primary care. San Pablo University Health Centre, Sevilla.Participants. 85 individuals (20 men and 65 women) with a wide range of age and blood pressure (BP), belonging to the population attended at the health centre or to its staff. People with arrhythmia and Korotkoff's V phase close to zero were excluded. Main measurements and results. BP and cardiac frequency (CF) measurements obtained with the SMBP devices to be validated were compared with readings on a mercury sphygmomanometer, used as the standard method. The differences between the SMBP devices and the gold standard were quantified and are presented on the scale proposed by the protocol of the British Hypertension Society (BHS). The mean (SD) of the systolic BP differences (in mm Hg) between the devices evaluated and the standard device was 1.084.73 for the automatic monitor and 1.255.30 for the semi-automatic one. The mean differences of diastolic BP were 0.444.03 for the automatic monitor, and 0.513.90 for the semi-automatic one. The cumulative percentage differences of systolic/ diastolic BP5, 10 and 15 mm Hg were 85.5, 98, 98.8/90.6, 98.4, 100% for the automatic monitor and 82.7, 95.7, 98.8/91, 99.6, 100% for the semi-automatic one. This supposes a Grade A on the BHS procedure, which is maintained on analysis of the results by blood pressure rankings. Conclusion. As both monitors meet the internationally accepted validation criteria, they can be recommended for the monitoring and self-monitoring of BP in patients with hypertension.
