Background: Prediabetes has been associated with unfavorable short-term outcome in patients with ischemic stroke (IS). However, its effect in the subset of young adult patients has not been fully assessed. Our aim was to study the association between prediabetes and 3-month outcome in young adult patients with IS.
Methods: This is a retrospective analysis of consecutive patients aged 18-55 years with a clinical diagnosis of acute IS between January 2010 and December 2016. According to their glucose profile, patients were divided in 3 groups: normal glucose metabolism, prediabetes, and diabetes. The outcome at 3 months was assessed by the modified Rankin Scale (mRS) and dichotomized as good (mRS score ≤2) and poor (mRS score >2) outcomes.
Results: A total of 247 patients were included, the median age was 49 years (interquartile range 42-53), and 144 (58.3%) were men. Prediabetes was diagnosed in 79 patients (32.0%) and diabetes was diagnosed in 45 patients (18.2%). Prediabetic (adjusted odds ratio [OR] 2.4, 95% confidence interval [CI] 1.1-5.1, P = .031) and diabetic (adjusted OR 2.8, 95% CI 1.3-6.1, P = .020) patients had a worse prognosis at 3 months. A statistical significant shift in the distribution of the mRS score at 3 months was found in prediabetic (adjusted OR 2.5, 95% CI .3-1.5, P = .002) and diabetic (adjusted OR 3.74, 95% CI .5-2.2, P = .002) patients.
Conclusion: In young adults with IS, prediabetes and diabetes increase the risk of unfavorable outcome at 3 months.
