What is the risk of stroke recurrence for elderly smokers?
The Cardiovascular Health Study (N=546) identified a substantially increased risk of stroke recurrence in elderly smokers, with an adjusted HR of 1.93 (95% CI, 1.43 2.61). A longitudinal study in Han Chinese individuals with ischemic stroke (N=421) identified an adjusted HR for smokers at 1 year of 3.0. The SMART study (Second Manifestations of Arterial Disease; N=4673) found that recurrent major atherosclerotic cardiovascular events occur 10 years later compared with persistent smokers.
