However, the association between the variation of neutrophil-to- lymphocyte ratio(ΔNLR) and the bleeding transformation (HT) as well as early neurological improvement (ENI) at 24 h after thrombolysis is still lacking. The purpose of the study was to investigate the correlation between ΔNLR and HT as well as ENI 24 h after thrombolytic therapy, and the relationship between ΔNLR and early outcomes after thrombolytic therapy in patients with different TOAST classifications. Methods: 234 patients with AIS who received intravenous thrombolysis were included. The patients were classified by TOAST classifications. Patients were grouped according to the presence or absence of HT and ENI. Results: The increase of NLR after thrombolysis was more obvious in patients with HT while the decrease of NLR was more obvious in patients with ENI. There was no significant difference in ΔNLR between patients with atherosclerotic type and those with cardiogenic embolization type, but there was a statistical difference in ΔNLR between patients with small artery occlusion type and those with large artery atherosclerosis mild type. Conclusion: ΔNLR was an independent influencing factor for HT and ENI in AIS patients after thrombolysis, and ΔNLR in small artery occlusive stroke patients was greater than that in patients of minor stroke of LAA group.展开更多
