Introduction: Cerebrovascular accidents are the third leading cause of mortality and the most important cause of morbidity in adults in the most of the world. Multiple factors such as Socioeconomic, lifestyle, environmental and genetic factors may be the cause of stroke risk differences in our community. This study was designed to evaluate the Stroke Risk Factor in persons above 55 years old without history of Stroke who referred to Health Centers in Hamadan on 2012.Material and Methods: In a Descriptive- Analytical study, 300 person above 55 years without history of stroke who referred to Health centers of Hamadan were selected (randomly),with regarded of inclusion and exclusion criteria and after explaining the research and its purposes, their permission was obtained. Their demographic data (such as age, gender), history of heart disease, hypertension and drug reception for it, diabetes, hyperlipidemia, smoking were filled in questionnaire. One EKG was performed (about the atrial fibrillation and signs of left ventricular hypertrophy).then data were analyzed and average tenth year stroke risk with use the Prof. Donald Smith software (stroke risk calculator) calculated.Results: The mean age, risk factors and systolic blood pressure in men and women were: 68.62±10006y, 2.16±1.33 and 129.05±18.71mmHg. History of diabetes mellitus, hyperlipidemia, smoking, hypertension(HTN), drug reception for HTN, drug reception in persons with history of HTN, SBP≥140mmHg, drug reception in persons with SBP≥140mmHg,Cardiovascular disease, atrial fibrillation(AF rhythm) and signs of left ventricular hypertrophy(LVH)in EKG have frequency: 19066%, 28%, 19%, 42023%, 34%, 29%, 59077%, 20033%, 3033%, 8033% respectively. The mean calculated stroke risk was for tenth year 10071%.This risk was 11074% in men and 9052% in women population.Conclusion: It’s can be concluded that with regard to transition of socioeconomic and community especially aging and international experience of epidemiologic transition, stroke risk factors and consecutive stroke risk in Hamadan as a small sample of a developing country are rapidly increasing . Its hope that experiences obtained in developed countries applied in preventive programs and healthy planning.
