	Introduction

 
After heart disease, stroke is the second leading cause of death worldwide in persons 15 years of age.¹ Stroke was responsible for an estimated 5.7 millions deaths in 2005, with 87% of the deaths occurring in low- and middle-income countries. It is the fourth leading cause of disease burden as determined by disability-adjusted life-years. In the United States, stroke caused an estimated 1 in 16 deaths in 2004; 780 000 new or recurrent strokes occurred; and 15% to 30% of stroke survivors were permanently disabled.² In the United States in 2008, the direct and indirect cost of stroke is estimated to be $65.5 billion. Globally, stroke death is anticipated to rise to 6.5 million in 2015 and 7.8 million in 2030.¹ Although stroke poses a major public health challenge, it is preventable.³ Observational epidemiological studies and clinical trials have laid the groundwork for well-developed evidence-based stroke prevention guidelines.
