Hyperglycemia on admission and diabetes mellitus type II are associated with unfavorable outcome in stroke patients. We studied whether impaired fasting glucose (IFG) is associated with unfavorable outcome in ischemic stroke patients treated with intravenous alteplase as well and if IFG is a stronger prognostic factor than hyperglycemia on admission.


We studied 220 consecutive patients with ischemic stroke treated with intravenous alteplase. In all nondiabetic patients, fasting glucose was determined on day 2–5. IFG was defined as fasting glucose level of ≥ 5.6 mmol/L, hyperglycemia on admission as glucose levels ≥ 7.9 mmol/L. The primary effect measure was the adjusted common odds ratio (acOR) for a shift in the direction of worse outcome on the modified Rankin Scale at 3 months, estimated with ordinal logistic regression, and adjusted for common prognostic factors.


The fasting glucose levels were available in 194 and admission glucose levels in 215 patients. Sixty-three (32.5%) had IFG, 58 (27%) hyperglycemia on admission and 32 (14.6%) pre-existent diabetes. Patients with IFG showed a shift towards worse functional outcome compared with patients with normal fasting glucose levels (acOR 2.77; 95% CI 1.54–4.97), which was stronger than hyperglycemia on admission (acOR 1.75; 95% CI 0.91–3.4).


IFG is associated with unfavorable outcome after treatment with intravenous alteplase for acute ischemic stroke. IFG predicts unfavorable outcome better than hyperglycemia on admission.
