Approximately 6.6 million Americans have had a stroke, and this prevalence is projected to increase by 20.5% by the year 2030.2,3 Of all strokes, 87% are ischemic whereas 13% are hemorrhagic.2 Stroke is a leading cause of long-term US disability. Among Medicare patients hospitalized with stroke, more than half are discharged to inpatient rehabilitation or a skilled nursing facility.2 Primary prevention of stroke is important because most strokes occur in people without known cerebrovascular disease.3 Preventing stroke depends on identifying risk factors, implementing appropriate lifestyle changes, and intervening to control modifiable risk factors.
