BACKGROUND: Hypertension is a major cardiovascular risk factor, but knowledge about the real magnitude of the problem and its determinants is lacking. AIM: To assess control of hypertension and evaluate medical resource use, in patients at high risk of cardiovascular disease. DESIGN: Multicentric cross-sectional study. METHODS: We collected data for 2205 adult patients from 36 centres, representative of all regions of Spain. Patients had attended out-patient clinics from July 2002 to August 2003, had an absolute cardiovascular risk > or =20% at 10 years (according to the Framingham guidelines), and had a diagnosis of hypertension. Pregnant and terminally ill patients were excluded. RESULTS: Hypertension was inadequately controlled in 1384 patients (62.8%). LDL cholesterol was higher in patients with uncontrolled hypertension (median 130.2 vs. 120.0 mg/dl, p < 0.001). Haemoglobin A(1c) in diabetic patients was also greater in those with uncontrolled hypertension (median 7.10% vs. 6.90%, p = 0.010). Uncontrolled hypertension was associated with the following variables, in descending strength of association: higher LDL cholesterol, taking antihypertensive medication, living in non-metropolitan areas, and higher body mass index. DISCUSSION: Hypertension is poorly controlled in most patients with a high risk of cardiovascular disease. Uncontrolled hypertension is frequently associated with poor control of other risk factors.
