Medical treatment of hypertension in Switzerland. The 2009 Swiss Hypertension Survey (SWISSHYPE)

OBJECTIVES: Despite a broad and efficient pharmacological antihypertensive armamentarium, blood pressure (BP) control is suboptimal and heterogeneous throughout Europe. Recent representative data from Switzerland are limited. The goal of the present survey was therefore to assess the actual control rate of high BP in Switzerland in accordance with current guidelines. The influence of risk factors, target organ damage and medication on BP levels and control was also evaluated.METHODS : A cross-sectional visit-based survey of ambulatory hypertensive patients was performed in 2009 in Switzerland. 281 randomly selected physicians provided data on 5 consecutive hypertensive patients attending their practices for BP follow-up. Data were anonymously collected on demographics, comorbidities and current medication, and BP was recorded. Subsequent modification of pharmacological antihypertensive therapy was assessed.RESULTS : Data from 1376 patients were available. Mean age was 65 +/- 12 years, 53.9% were male subjects. 26.4% had complicated hypertension. Overall, BP control (
