Objective  To analyze the influencing factors of hemorrhagic transformation (HT) after intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in patients with acute ischemic stroke (AIS). Methods  AIS patients hospitalized in the Department of Neurology of the First Affiliated Hospital of Zhengzhou University between June 2017 and June 2020 and receiving rt-PA intravenous thrombolysis were selected. Patients were divided into two groups according to whether they had HT, HT group and non-HT group. General data such as patient’s age, sex, past history, score of National Institute of Health Stroke Scale (NIHSS) before thrombolysis, and related biochemical examination indicators were collected, to analyze the difference between the patients with HT or not, and analyze the related factors affecting the HT of AIS patients after intravenous thrombolysis. Results  A total of patients 323 were included. Among them, 46 cases (14.2%) had HT, and 277 cases (85.8%) had no-HT. Except for serum free triiodothyronine (FT3), atrial fibrillation, hypertension, cerebral infarction area, NIHSS score before thrombolysis, uric acid, blood glucose before thrombolysis, white blood cell count, albumin level, alanine aminotransferase, aspartate aminotransferase / alanine aminotransferase and C-reactive protein (P<0.05), there was no significant difference in other indexes between the two groups (P>0.05). Logistic regression analysis showed that NIHSS score≥13 before thrombolysis, aspartate aminotransferase / alanine aminotransferase, blood glucose before thrombolysis≥12.74 mmol/L, low FT3 level, massive cerebral infarction, and atrial fibrillation were independent risk factors for HT after thrombolysis in AIS. Conclusions  FT3 and aspartate aminotransferase / alanine aminotransferase levels may be good biomarkers for predicting HT after intravenous thrombolysis. For patients with reduced albumin and uric acid levels, supplementation of exogenous uric acid and albumin may help reduce the risk of HT after AIS thrombolysis.
