7 mill in US
incidence
795,000 people per yea
610,000 new strokes
185,00 recurrent
CVA is the most common cause of
chronic disability
how much does incidence increase every decade
doubles after 55
how often does someone suffer a new stroke
every 40 sec
how often does someone die from a stroke
every 3-4 min
high risk pop
men
african americans

30% higher incidence
80% greater risk of developing a subsequent stroke
increased exposure to modifiable risk factors
african americans
black men have a 50% greater incidence than white men
black women have a 130% higher incidence than white women
mortality –> ischemic CVA
17-25% within the first month
hemorrhagic CVA mortality
40-60% within the first month
when does survivability approach normal
~18 months post CVA
