    Abstract:
    Hypertension represents a high health cost because of its prevalence, its low level of diagnosis and control, and its role as a primary risk factor for other cardiovascular diseases. According to the JNC 7 report, hypertensive individuals have blood pressures of 140/90 mm Hg or higher; recommended treatment reduces these values to below 120/80 mm Hg. Co-morbidity and the presence of other risk factors must also be considered. In a random sample of 458 hypertensive patients from 6 Colombian cities, the effectiveness, tolerance and adherence to treatment was compared in cases with treatment of at least one year's duration. During routine blood pressure examinations, trained nurses obtained patient consent and additional anthropometric data, such as including co-morbidity, risk factors, antihypertensive medication prescribed, dosages and usage of unrelated medications. Some of the data were retrieved from the patients' medical histories. The average age of the patients was 57.6 +/- 13 years, with 67.5% women; 92% with complete adherence to the treatment and 59% not reporting adverse events associated with the medication. Forty-four percent were treated with antihypertensive monotherapy with the most commonly prescribed medications as follows (in order): hydrochlorothiazide, verapamil, enalapril, metoprolol and propanolol. Forty-five percent (n=207) were control patients, 35% were in a hypertensive stage 1 and 19.7% were in stage 2. Multivariate analysis showed that uncontrolled hypertension was significantly associated with geriatrics receiving a combination of antihypertensive medication and residence in three cities--Ibagué, Barranquilla and Manizales--where smaller daily doses of hypertensive medications are prescribed. Health care teams are advised to adjust doses carefully to obtain clearly defined therapeutic objectives.
