Stroke is a major public health problem that contributes significantly to the global burden of disease.  It is the most common cause of adult disability and the third leading cause of death worldwide (following coronary heart disease and cancer).  An effective global strategy to reduce the risk of premature stroke mandates systematic evaluation of the contribution of the risk factors in various ethnic groups and geographical locations.  The overall purpose of INTERSTROKE is to learn about the role of known risk factors (e.g. blood pressure) and emerging risk factors (e.g. genetics) for stroke in different regions of the world and ethnic groups.  We will compare risk factors in people with stroke (Cases) to people without stroke (Controls) in a large, international Case-control study that will include approximately 24,000 cases and controls from more than 30 countries.  INTERSTROKE will have enormous implications for our understanding of the causes of stroke worldwide.  It will provide key information to help guide population health initiatives aimed at preventing stroke in low and high-income countries.
