Methods: A retrospective analysis was performed on patients with anterior circulation AIS who received intravenous thrombolysis in the hospital from 2020 to 2024. HT was detected by brain CT or MRI within 7 days of admission. We compare baseline demographic, clinical, and laboratory data between the HT group and the non-HT group and between the different types of HT groups recorded according to the ECASS III. Results: 701 AIS patients who underwent intravenous rt-PA thrombolysis within 4.5 h after onset of AIS were divided into HT group (102) and Non-HT group (599). Compared with patients without HT, the UA level of HT patients was significantly reduced (251.85 ± 92.13 vs 307.73 ± 76.66, p < 0.01), but there was no significant difference between UA and HT types (p = 0.64). After adjusting for confounding factors, compared with the first quartile, the risk of HT in the fourth quartile was significantly reduced (OR 0.187, 95% CI 0.067~ 0.526, p = 0.001). Conclusion: Low levels of SUA may increase the risk of HT after intravenous thrombolysis.展开更多
