[Representative observations of therapies in arterial hypertension]

An enquiry was conducted by 125 general practitioners in 1998 concerning 1,204 hypertensive patients (55.5% women, 71% aged 60 or over, 54% with normalised blood pressures). At the first visit (inclusion) the most frequently described therapeutic classes were: diuretics (19%), betablockers (19%), ACE inhibitors (14%), angiotensin II inhibitors (7%). The use of fixed associations was uncommon except for that of ACE inhibitors with diuretics (10.5%). The incidence of normalisation of blood pressure was the same in all therapeutic classes, about 55%, comparable to reported data; however, 42% of non-normalised patients were on monotherapy. Only 7.4% of patients had their treatment changed at inclusion: 3.8% of normalised and 11.2% of non-normalised hypertensives. This low incidence of change of treatment is partially explained by the patients' own opinion about the treatment of their hypertension. In fact, the majority of therapeutic changes is observed when the patient and the doctor both concur. This data on the treatment of hypertension confirms the respective usage of the main therapeutic classes but the limited number of treatment changes at inclusion does not allow yet assessment of these new choices. One year follow-up of this cohort to the second phase of results should provide important information with respect to this point.
