Abstract
Background
Hemorrhagic transformation (HT) is a common complication of acute ischemic stroke (AIS), and inflammation has been found to play an important role in the occurrence of HT. We aimed to investigate the impact of lymphocyte-to-monocyte ratio (LMR), a maker of inflammatory status, on HT in patients with AIS.
Methods
Consecutive AIS patients within 7 days from stroke onset were enrolled between January 2016 and October 2017. LMR was calculated according to lymphocyte and monocyte counts obtained within 24 h on admission. Patients were categorized into three groups according to LMR tertiles. HT was detected by follow-up computed tomography (CT) or magnetic resonance imaging (MRI) during hospitalization. The multivariate logistic analysis was used to evaluate the independent relationship between LMR and HT.
Results
A total of 1005 patients were finally included. HT was observed in 99 (9.9%) patients, with 51 (5.1%) hemorrhagic infarction (HI) and 48 (4.8%) parenchymal hematoma (PH). After adjustment for potential confounders, the odds ratio (OR) of HT was 0.523 (95% confidence interval [CI] 0.293–0.936, P = 0.029) for the highest LMR tertile compared with the lowest tertile. Multiple-adjusted spline regression model showed a nonlinear approximately L-shaped relationship between LMR levels and HT (P for nonlinear trend = 0.030). There was no significant association of baseline LMR with PH (OR 0.562, 95% CI 0.249–1.268, P = 0.165).
Conclusion
Lower LMR was independently related to higher risk of HT in patients with AIS. Admission LMR may be used as one of the predictors for HT. Further prospective multicenter studies are needed to validate our findings.
