Abstract:

Objective

To analyze the relationship between the stress hyperglycemia ratio (SHR) and the prognosis of acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT).

Methods

This retrospective study included 158 AIS patients who underwent IVT at the First Affiliated Hospital of the University of Science and Technology of China between January 2022 and December 2023. Baseline clinical data were collected via the hospital's electronic medical record system. Patients were divided into a favorable- [modified Rankin scale (mRS) score ≤3] and a poor-prognosis (mRS score >3) groups based on neurological recovery at 90 days. Univariate analysis (t-test, Mann-Whitney U test, or χ2 test) compared general clinical data and laboratory indicators between the two groups. Univariate Logistic regression identified factors associated with poor prognosis, while multivariate Logistic regression (adjusted for confounders) analyzed the independent association between SHR and IVT outcomes. Restricted cubic spline models further assessed nonlinear associations between SHR and prognosis.

Results

Among 158 AIS patients, 135 (85.4%) had favorable IVT outcomes and 23 (14.6%) had poor outcomes. Compared with the poor-prognosis group, the favorable-prognosis group showed significantly higher levels of albumin [(44.20±4.66) g/L vs (40.24±5.43) g/L, t=3.672, P<0.001], uric acid [(348.89±95.39) μmol/L vs (305.54±86.36) μmol/L, t=2.041, P=0.043], LDL-C [(2.76±0.89) mmol/L vs (2.35±0.56) mmol/L, t=2.091, P=0.038], total cholesterol [(4.69±1.12) mmol/L vs (4.00±0.70) mmol/L, t=2.780, P=0.006], and aspartate aminotransferase [22.00 (18.00, 28.30) U/L vs 19.00 (15.00, 24.80) U/L, Z=-2.096, P=0.036]. Conversely, the favorable-prognosis group had significantly lower NIHSS scores before thrombolysis [6.00 (3.00, 11.00) vs 16.00 (11.00, 20.00), Z=-4.915, P<0.001], direct bilirubin [3.20 (2.10, 4.60) μmol/L vs 4.20 (2.90, 5.60) μmol/L, Z=-2.695, P=0.007], and SHR [1.02 (0.89, 1.18) vs 1.19 (1.02, 1.46), Z=-2.576, P=0.010]. Univariate Logistic regression identified SHR (OR=5.184, 95%CI: 1.202 - 22.360), NIHSS score before thrombolysis (OR=1.189, 95%CI: 1.101 - 1.283), albumin (OR=0.830, 95%CI: 0.749 - 0.920), uric acid (OR=0.994, 95%CI: 0.989 - 1.000), LDL-C (OR=0.515, 95%CI: 0.273 - 0.971), total cholesterol (OR=0.467, 95%CI: 0.266 - 0.820), and direct bilirubin (OR=1.483, 95%CI: 1.154 - 1.906) as factors associated with poor prognosis (all P<0.05). Multivariate analysis confirmed SHR as an independent predictor of poor IVT outcomes after adjusting for confounders. Restricted cubic spline models revealed a nonlinear relationship: when SHR was <1.03, the risk of poor prognosis increased slowly with rising SHR; when SHR was ≥1.03, the risk escalated rapidly.

Conclusion

In AIS patients receiving IVT, elevated SHR is independently associated with poor 90-day outcomes.
