Background: This aimed to elucidate the impact of stress hyperglycemia on early neurological deterioration (END) in patients with acute non-cardiogenic cerebral infarction who did not experience hemorrhagic transformation following intravenous thrombolysis to identify risk factors associated with END.
Methods: This retrospective case-control study analyzed data from consecutive patients who received intravenous thrombolysis for acute ischemic stroke (AIS) without hemorrhagic transformation at the Stroke Center of The Fifth Affiliated Hospital of Sun Yat-sen University from January 2018 to February 2023. END was defined as an increase of more than 2 points on the National Institutes of Health Stroke Scale (NIHSS) within 7 days of admission.
Results: A total of 250 patients (56 males, 22.4%) were included, with a mean age of 63.34 ± 12.90 years. Of them, 41 were classified into the END group and 209 into the non-END group. Stress hyperglycemia ratio (SHR) demonstrated a significant correlation with END (r=-0.003, P = 0.003). HbA1c (OR = 0.68, 95% CI: 0.481-0.921) and SHR (OR = 0.00, 95% CI: 0.0-0.051) were independently associated with END. Receiver-operating characteristic (ROC) curve analysis indicated that SHR had a sensitivity of 79.9%, specificity of 88.8%, and an area under the curve (AUC) of 0.857 for predicting END.
Conclusions: SHR was significantly associated with END in patients with acute non-cardioembolic cerebral infarction who did not undergo hemorrhagic transformation after intravenous thrombolysis.
