title: [Arterial hypertension and control in Brazzaville (Congo): role of ambulatory blood pressure monitoring (ABPM)].
abstract: OBJECTIVE
  To evaluate the rate control in the hypertensive patients and to identify the predictive factors of non-control.
  
  
  METHODS
  It was about a cross-sectional study with prospective collection of data over a period of 36 months. It has been held in Brazzaville, and included a consecutive series of 620 hypertensive patients known and treated for at least 6 weeks, having profited from an ambulatory blood pressure monitoring (ABPM) with therapeutic aiming. We used the TONOPORT V and the software Cardiosoft 6.51 of GE Health Care, respectively for the recording and the data analysis. The threshold fixed on the average of 24-hour was BP<130/80 mmHg, and the patients divided into two groups according to whether they were or not controlled.
  
  
  RESULTS
  They were 352 men (56.8%) and 268 women (43.2%), old on average of 53.8 ± 9.7 years (ranges: 29 and 89 years). The standard of living of the patients was average in 330 cases (53.2%), weak in 132 cases (21.3%), and high in 71 cases (11.5%). The other associated risk factors were sedentariness in 275 cases (44.4%), overweight/obesity in 134 cases (21.6%), dyslipidemia in 121 cases (19.5%), diabetes mellitus in 90 cases (14.5%), and tobacco addiction in 25 cases (4%). The hypertension, old of 5.8 ± 5.7 years on average, was controlled among 215 patients (34.7%). The 24- hour BP average was 139 ± 14 mmHg for the SBP and 88.2 ± 10.2 mmHg for the DBP. The awake and asleep BP averages were respectively 141 ± 14 mmHg and 133 ± 16.2 mmHg for the SBP, 90.5 ± 10.5 and 81.2 ± 11.1 mmHg for the DBP. The antihypertensive protocol used was a monotherapy in 130 cases (21%), bitherapy in 287 cases (46.3%), tritherapy in 154 cases (24.8%), quadritherapy or more in 27 cases (4.3%). Prevalence of non-dipping was 43%. Age and male gender were the significant predictors of poor control.
  
  
  CONCLUSIONS
  The rate control of hypertension in our study population remains low. Its improvement passes by the education of the hypertensive patients and the improvement of their living conditions.
