Abstract
Although patients with transient ischemic attack (TIA) experience cardiovascular events frequently, strong clinical predictors of recurrence are lacking. High-sensitivity C-reactive protein (hs-CRP) has been shown to be a powerful predictor of future first-ever and recurrent coronary and cerebral ischemic events. We aimed to investigate the relationship between hs-CRP and the risk of further ischemic events in TIA patients. High-sensitivity C-reactive protein level was determined 4.1 mg/l (HR 2.81, 95% CI 1.12-7.10, P = 0.03) as independent predictors of stroke. Moreover, age (HR 1.05, 95% CI 1.01-1.10, P = 0.02), large-artery occlusive disease (HR 3.12, 95% CI 1.48-6.58, P < 0.01), coronary disease (HR 2.39, 95% CI 1.11-5.16, P = 0.03), and hs-CRP> 4.1 mg/l (HR 2.71, 95% CI 1.16-6.30, P = 0.02) were also independent predictors of any vascular event. High-sensitivity C-reactive protein serum level predicts further ischemic events following TIA. Routine CRP measurement might be a useful tool for identifying high-risk TIA patients in order to plan aggressive diagnostic protocols and prevention therapies.
