Higher fasting blood glucose was associated with worse in‐hospital clinical outcomes in patients with primary intracerebral hemorrhage: From a large‐scale nationwide longitudinal registry

INTRODUCTION: Studies that investigated the relationship between fasting blood glucose (FBG) and intracerebral hemorrhage (ICH) outcomes were insufficient. AIM: We aimed to investigate the association between FBG level and in‐hospital clinical outcomes in patients with primary ICH. RESULTS: A total of 34,507 patients were enrolled in the final study. Compared with the reference group, the ≥6.1 and <7 mmol/L group showed nonsignificant higher in‐hospital mortality (adjusted odds ratio [OR] 1.20, 95% confidence interval [CI] 0.69–2.11, p = 0.52), and a significant higher proportion of intracranial hematoma evacuation (adjusted OR 1.56, 95% CI 1.26–1.92, p < 0.001). The ≥7 mmol/L group showed both significant higher in‐hospital mortality (adjusted OR 2.08, 95% CI 1.42–3.04, p = 0.52) and a significant higher proportion of intracranial hematoma evacuation (adjusted OR 2.09, 95% CI 1.78–2.47, p < 0.001). CONCLUSION: Higher FBG level was correlated with both higher mortality and proportion of evacuation of intracranial hematoma.
