Can High-Sensitivity C-Reactive Protein and Plasma Homocysteine Levels Independently Predict the Prognosis of Patients with Functional Disability after First-Ever Ischemic Stroke?

Abstract

Background: The prognosis of functional disability in patients with cerebrovascular disease has not been well established. Therefore, we conducted this study to determine the prognostic significance of high-sensitivity C-reactive protein (hs-CRP) and homocysteine (Hcy) levels in patients with functional disability after acute first-ever ischemic stroke. Method: A total of 309 patients with first-ever stroke were examined within 24 h after symptom onset. Hcy was measured at admission, and hs-CRP measurements were made at admission and on the seventh hospital day. The correlations between the concentration of hs-CRP or Hcy and functional disability at 1, 3, 6 and 12 months after stroke onset were analyzed. Results: The present study showed that both hs-CRP values on admission and on the seventh hospital day were significantly correlated with modified Rankin Scale (mRS) scores obtained at 4 times after the onset of stroke. These results also demonstrated that mRS scores are more closely associated with hs-CRP values on the seventh hospital day than on admission. However, there was no significant relationship between Hcy and mRS scores during the 12-month follow-up period. Conclusion: According to the present study, we cautiously suggest that hs-CRP values on the subacute phase have sufficient value as a predictor of the prognosis of functional disability after first-ever stroke.
