Correlation analysis of inflammatory markers with the short-term prognosis of acute ischaemic stroke

Abstract

Stroke is the second leading cause of death worldwide, and China has the highest stroke incidence in the world. The systemic inflammatory response index (SIRI), systemic inflammatory response index (SIRI), systemic immune-inflammatory index (SII), neutrophil-to-high-density lipoprotein ratio (NHR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and monocyte-to-lymphocyte ratio (MLR) have clinical in predicting the prognosis of acute ischaemic stroke (AIS) patients. No studies have compared the predictive value of these six composite inflammatory markers. This study included 516 AIS patients with AIS symptoms for < 24 h. The short-term prognosis of AIS patients at 30 days was assessed using the modified Rankin scale (mRS), an mRS score > 2 defining poor prognosis. The results of the univariate analysis showed that all six composite inflammatory indices, SIRI, SII, NHR, NLR, PLR and MLR, were associated with a poor prognosis in patients with AIS. All six composite inflammatory indicators correlated with the short-term prognosis of AIS patients. The six composite inflammation indicators were included in the binary logistic regression, and the results showed that SIRI, NLR and PLR were found to be independent risk factors for poor short-term prognosis in AIS patients. Among the six inflammatory markers, SIRI, NLR and PLR were the most clinically valuable for predicting the short-term prognosis of patients with AIS. Peripheral blood indices are easy to obtain clinically and can provide important clinical value for early prognosis and treatment adjustment.
