Abstract:
Objective:To investigate the value of hemorrhage after thrombolytic (HAT) score and neutrophil to lymphocyte ratio (NLR) in combination predicting symptomatic intracerebral hemorrhage (sICH) after intravenous thrombolysis in patients with acute ischemic stroke (AIS).Methods:Consective patients with AIS received intravenous thrombolysis with ateplase in Tianjin TEDA Hospital from January 2016 to December 2021 were retrospectively enrolled. sICH was defined as cerebral CT showing hemorrhage at any part of the brain after intravenous thrombolysis, and the National Institutes of Health Stroke Scale (NIHSS) score was increased by≥4 compared with the baseline, or there was a manifestation indicating clinical aggravation. Univariate analysis was used to compare the baseline data of sICH group and non-sICH group. A binary multivariate logistic regression model was used to determine the independent influencing factors of sICH. The receiver operating characteristic (ROC) curve was used to evaluate the value of HAT score and NLR in combination predicting sICH. Results:A total of 429 patients with AIS were enrolled. Univariate analysis showed that there were significant differences in atrial fibrillation, systolic blood pressure, NLR, HAT score and NIHSS score between the sICH group and the non-sICH group (all P<0.05). Multivariate analysis showed that NLR (odds ratio [ OR] 1.405, 95% confidence interval [ CI] 1.193-2.958), HAT score ( OR 1.512, 95% CI 1.207-3.169) and NIHSS score ( OR 1.221, 95% CI 1.082-2.634) had significant independent correlation with sICH after adjusting for atrial fibrillation and systolic blood pressure. The ROC curve showed that the areas under the curve of HAT score, NLR and their combination predicting sICH were 0.719 (95% CI 0.609-0.832), 0.723 (95% CI 0.618-0.835) and 0.854 (95% CI 0.765-0.931), respectively. The areas under the curve of the two methods in combination were significantly larger than those of the single method ( P=0.029 and 0.032, respectively), and their sensitivity and specificity were 74.1% and 83.5% respectively. Conclusion:Combined HAT score and NLR is of high value in predicting sICH after intravenous thrombolysis in patients with AIS, and has clinical application potential.
