Background Hypertension is the main risk factor for most cardiovascular diseases. Blood pressure (BP) control has been shown to reduce the incidence of stroke, myocardial infarction, renal diseases and heart failure. Although BP lowering is effective, few population programs can achieve BP control. A coordinated and organized system from the Brazilian Ministry of Healthy involving Family Health Strategy (FHS), a program for the prevention of chronic disease, and the Popular Pharmacy Program (PPP), which subsidizes medications for the population, could allow an earlier identification and better BP control. Matão Controlling Hypertension (MatCH) is a community-based population project that aims to apply an organized, integrated and coordinated program in the city of Matão, Brazil, involving FSH and PPP in order to actively search, treat and follow-up hypertensive subjects.
