Background and purpose: Elevated plasma C‐reactive protein (CRP) has been suggested as a risk factor for ischemic stroke (IS) and coronary ischemic disease. Evidence has shown that high‐sensitivity CRP (hs‐CRP) is related to a worsening prognosis after IS, but hs‐CRP was rare in a large‐sample study in a Chinese population. We investigated the associations between hs‐CRP and outcome of Chinese patients after acute IS. Methods: Seven hundred and forty‐one consecutive acute IS patients (74.9% male, mean age 60.9 years), with baseline characteristics and hs‐CRP measured within 24 h after hospitalization, were admitted in this study. We also prospectively followed up for clinical outcome and death 3 months after disease onset. hs‐CRP was divided into two categories: hs‐CRP >3 mg/L and hs‐CRP ≤3 mg/L. Survival analysis using multivariable Cox regression was performed to analyze the association between hs‐CRP and stroke outcomes after adjusting for potential confounding factors. Results: Compared with low hs‐CRP, patients with high hs‐CRP (>3 mg/L) had a significantly higher rate of all‐cause death (0.71% vs. 10.00%; P < 0.001) at 3 months after stroke onset. High hs‐CRP was an independent risk factor for all‐cause death (HR, 6.48; 95% CI, 1.41 to 29.8; P= 0.016), as well as history of atrial fibrillation (HR, 5.24; 95% CI, 1.83 to 15.0; P= 0.002), no statin therapy during hospitalization (HR, 4.56; 95% CI, 2.18 to 9.55; P < 0.001), high homocysteine (>15.1 mmol/L) (HR, 2.66; 95% CI, 1.26 to 5.60; P= 0.01); fasting glucose (>6.1 mmol/L) (HR, 9.14; 95% CI, 3.34 to 25.0; P < 0.001), NIHSS at admission (HR, 2.35; 95% CI, 1.35 to 4.09; P= 0.003) and history of coronary heart disease (CHD) (HR, 2.34; 95% CI, 1.06 to 5.17; P= 0.035). Kaplan–Meier survival curves showed a higher risk of death for patients with hs‐CRP >3 mg/L (P= 0.016). Conclusion: Elevated plasma hs‐CRP independently predicted risk of all‐cause death within 3 months after acute IS in Chinese patients. |
