Objective  To explore the association between C-reactive protein (CRP) change and the prognosis of patients with stroke. Methods  Individuals who were diagnosed with stroke from the 2011 China Health and Retirement Longitudinal Study (CHARLS) registry were included. The baseline characteristics in 2011, blood tests in 2011 and 2015, and follow-up data in 2018 were collected. The patients were divided into three groups according to their CPR change from 2011 to 2015, and the cut-off values of CRP change were 0 and 5 mg/L. Logistic regression analysis was performed to evaluate the association between CRP change and the risk of death after stroke. Results  A total of 1065 participants diagnosed in 2011 were enrolled. There were 383 participants in the CRP decreased group (CRP change ranging from –74.30 to –0.01 mg/L), 584 participants in the CRP stable group (CRP change ranging from 0 to 4.98 mg/L), and 98 participants in the CRP increased group (CRP change ranging from 5.00 to 79.27 mg/L). By 2018, the numbers (rates) of deaths in CRP decreased group, CRP stable group, and CRP increased group were 25 (6.53%), 33 (5.65%), and 13 (13.27%), respectively, and the difference in the mortality among the three groups was statistically significant (P=0.020). Logistic regression analysis showed that the CRP change≥5 mg/L was associated with a higher risk of death after stroke [odds ratio=2.332, 95% confidence interval (1.099, 4.946), P=0.027]. Conclusions  Increasing CRP levels over time may indicate an increased risk of death in stroke patients. A 4-year increase in CRP greater than 5 mg/L may be an independent predictor of the risk of long-term death in stroke patients.
