Stratifying by Blood Glucose Levels to Predict Hemorrhagic Transformation Risk Post-Rt-PA in Acute Ischemic Stroke.

Stroke is a leading cause of disability and mortality worldwide, posing a significant public health challenge. While treatment of acute ischemic stroke (AIS) with recombinant tissue plasminogen activator (rt-PA) is effective but increases the risk of hemorrhagic transformation (HT). This study aimed to explore the determinants of HT in AIS patients treated with rt-PA and investigate the association between blood glucose levels and HT risk. Methods: We conducted a prospective cohort study at the First Affiliated Hospital of Harbin Medical University from January 2018 to December 2021. Patients with AIS and who received rt-PA within 4.5 hours of symptom onset were included. Demographic, clinical, laboratory, and imaging data were collected. Results: Of the 426 patients, 15% experienced HT post-rt-PA, occurred more frequently in patients with a history of cardiac embolism, higher prethrombolysis NIHSS scores, and elevated fasting blood glucose (FBG) levels. The frequency of HT was higher in non-diabetic patients with FBG levels ≥ 7.0 mmol/L compared to diabetic patients. Elevated blood glucose levels were significantly associated with HT, regardless of diabetes history. Conclusion: The findings suggest importance of precise glycemic control during AIS management to improve patient outcomes, particularly in non-diabetic patients. Future protocols for AIS treatment should incorporate these findings to reduce HT risks. Further large-scale studies are needed to confirm these associations and guide clinical practices.
