The role of high high-sensitivity C-reactive protein levels at admission on poor prognosis after acute ischemic stroke

Objective: Plasma high hypersensitive C-reactive protein (hs-CRP) levels are associated with risk and prognosis of vascular diseases. The clinical implications of markedly elevated hs-CRP levels are more discovered in the onset and development of stroke. The aim of this study is to determine the association of plasma hs-CRP levels on the prognosis in patients with acute ischemic stroke. Methods: Retrospective analysis of a single-center database of consecutive cases for acute cerebral infarction (ACI) from January 1 2012 to December 30 2016 was performed. Significant predictors of the dependent variable variance were identified by standard linear, univariate and multivariate, or binary logistic regression modeling. Multivariate regression analysis was introduced to investigate the relationship between plasma hs-CRP levels at admission and change in National Institutes of Health Stroke Scale (NIHSS) score at discharge. Results: The percentages of hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation, body mass index (BMI) and chronic kidney disease were raised with the increase of hs-CRP plasma concentration at admission among all patients (p < 0.05). ACI patients with large-artery atherosclerosis had an increasing percentage with the increase of hs-CRP mean value (p < 0.05). The initial NIHSS scores, the acute infection rate and age advance also increased with the increase of hs-CRP plasma concentration at admission (p < 0.05). The ratio of neurological improvement increased with the decrease of plasma hs-CRP concentration (p < 0.05). The neurological deterioration and poor prognosis increased with the increase of plasma hs-CRP concentration (p < 0.05). Conclusion: High plasma hs-CRP levels are associated with worse outcomes in the ACI patients. Monitoring plasma hs-CRP levels and cutting down the elevated plasma hs-CRP levels will be beneficial in screening and treatment decisions for the prognosis of acute ischemic stroke.
