The stress hyperglycaemia ratio (SHR) is associated with the severity and adverse outcomes of ischaemic stroke in young adults. Higher SHR values are linked to more severe stroke and poor functional outcomes at 90-day follow-up, especially in non-diabetic patients. This study suggests that SHR may be an important marker for assessing the prognosis of ischaemic stroke in young adults.
Introduction: Stress hyperglycaemia is common in stroke. Recently, the stress hyperglycaemia ratio (SHR) has been proposed as a novel marker for stress hyperglycaemia and found to be associated with adverse outcomes in many diseases. However, data regarding the impact of the SHR on ischaemic stroke, especially in young adults, are limited. Therefore, the aim of this study was to investigate whether the SHR is associated with stroke severity and adverse outcomes in young adults with ischaemic stroke or transient ischaemic attack (TIA). Methods: We retrospectively recruited patients aged 18-45 years with acute ischaemic stroke or TIA. The SHR was calculated as fasting blood glucose (FBG) divided by glycated haemoglobin. The primary and secondary outcomes were 90-day poor functional outcomes and stroke severity on admission, respectively. Multivariable logistic regression, restricted cubic spline models, and subgroup analysis were performed to validate the relationship between the SHR and ischaemic stroke or TIA in young adults. Results: A total of 687 young adults (mean age 36.9 years) were recruited. Among them, 119 (17.3%) patients had prior diabetes, and 568 (82.7%) did not. The SHR was significantly associated with stroke severity and poor functional outcome. Compared with patients with lower SHR values, patients with higher SHR values were more likely to have moderate-to-severe stroke. The multivariable-adjusted OR (95% CI) was 1.70 (1.21-2.39) after adjusting for all potential confounders excluding FBG and 1.50 (1.03-2.17) after FBG adjustment. The restricted cubic spline showed a J-shaped association between the SHR and moderate-to-severe stroke. Compared with patients with lower SHR values, patients with higher SHR values were more likely to have poor functional outcome at 90-day follow-up. The multivariable-adjusted OR (95% CI) was 1.95 (1.12-3.41) after adjusting for all potential confounders excluding FBG and 1.84 (1.01-3.36) after FBG adjustment. A J-shaped association was found between the SHR and poor functional outcomes at the 90-day follow-up. In the subgroup analysis, SHR was independently associated with more severe stroke (OR, 1.79, 95% CI, 1.18-2.72) and poor functional outcomes (OR, 2.11, 95% CI, 1.32-3.35) in nondiabetic patients but not in diabetic patients in multivariate logistic analysis. Despite this, the interaction effects of prior diabetes on the association between the SHR and stroke severity and poor functional outcomes did not reach statistical significance. Conclusion: The SHR is independently related to more severe stroke and an increased risk of poor functional outcomes among young adults with ischaemic stroke or TIA.
