BackgroundIn ischemic stroke, increased glycated hemoglobin (HbA1c) and glucose levels are associated with worse outcome following thrombolysis, and possibly, endovascular thrombectomy.ObjectiveTo evaluate the association between admission HbA1c and glucose levels and outcome following endovascular thrombectomy.MethodsConsecutive patients treated with endovascular thrombectomy with admission HbA1c and glucose levels were included. The primary outcome was functional independence, defined as a modified Rankin Scale score of 0-2 at 3 months. Secondary outcomes included successful reperfusion (modified Thrombolysis in Cerebral Infarction 2b-3), early neurological improvement (reduction in National Institutes of Health Stroke Scale (NIHSS) score ≥8 points, or NIHSS score of 0-1 at 24 hours), symptomatic intracerebral hemorrhage (sICH), and mortality at 3 months.Results223 patients (136 (61%) men; mean±SD age 64.5±14.6) were included. The median (IQR) HbA1c and glucose were 39 (36-45) mmol/mol and 6.9 (5.8-8.4) mmol/L, respectively. Multiple logistic regression analysis demonstrated that increasing HbA1c levels (per 10 mmol/mol) were associated with reduced functional independence (OR=0.76; 95% CI 0.60-0.96; p=0.02), increased sICH (OR=1.33; 95% CI 1.03 to 1.71; p=0.03), and increased mortality (OR=1.26; 95% CI 1.01 to 1.57; p=0.04). There were no significant associations between glucose levels and outcome measures (all p>0.05).ConclusionsHbA1c levels are an independent predictor of worse outcome following endovascular thrombectomy. The addition of HbA1c to decision-support tools for endovascular thrombectomy should be evaluated in future studies.© Author(s) (or their employer(s)) 2020. No commercial re-use.
