PHYSICIAN ASSESSMENT OF STROKE RISK IN HYPERTENSIVE PATIENTS IN THE MIDDLE EAST AND AFRICA: RESULTS OF THE ACTION SURVEY

the risk of sTroke in hypertensION Survey Group) Objectives: In the absence of reliable, con-temporary national data, the ACTION survey was designed to: a) provide preliminary data on stroke risk in the MEA (Middle East and Africa); b) describe the contribution of specific cardiovascular risk factors; 3) assess blood pressure (BP) control. Design and Patients: This was a multi-center observational study in nine countries in the MEA region. From 2003 to 2005, 562 physicians from a variety of specialties re-corded observations of cardiovascular risk factors in 4,747 hypertensive patients, aged 54–80 years. The 10-year absolute stroke risk was calculated using a scoring system based on the Framingham Heart Study observations, and comparisons made with an age-matched co-hort. Results: The mean 10-year stroke risk was estimated at 22.7 % and was significantly higher for men (25.4%) than for women (19.5%) (P,.001) and for diabetics (28.2%) than for non-diabetics (19.4%) (P,.001). Compared with an age-matched Framingham cohort, the estimated stroke risk in our population was almost double, and was significantly higher for females (212%) than for males (192%) (P,.001). Hypertension, diabetes, left ventricular hypertrophy, and smoking were major contributing risk factors, as were physical inactivity and elevated cholesterol. Blood pressure was controlled in only 18 % of the population and in 12 % of diabetics. Conclusion: Physicians of all specialties were willing to participate in stroke risk assessment. The risk of stroke in hypertensive patients in the MEA region is high, and is higher than would be predicted using Framingham data, particularly for females. Hypertension appears to be poorly controlled in more than 80 % of hypertensive patients in the MEA region. (Eth
