Abstract Backgrounds Pre-diabetes is an intermediate state between normal glucose metabolism and diabetes. Recent studies suggest that the presence of pre-diabetes is associated with poor outcomes after AIS. However, the results have been controversial. This study examines whether pre-diabetes influences the patients’ short and long-term outcomes for AIS using IV thrombolysis. Methods We enrolled 661 AIS patients with IV thrombolysis. Based on the 2010 ADA guidelines, patients were classified as pre-diabetes, with HbA1c levels of 5.7–6.4%; diabetes, with HbA1c levels more than 6.5%; and NGM (normal glucose metabolism), with HbA1c levels less than 5.7%. We investigated short-term outcomes, including early neurologic deterioration (END), in-hospital death, and poor functional outcomes (mRS > 2) at 90 days. As for long-term outcomes, poor functional outcomes were measured at 1 year. Results Of the 661 AIS patients treated with IV thrombolysis, 197 patients (29.8%) were diagnosed with pre-diabetes, and 210 (31.8%) were diagnosed with diabetes. In a multivariate analysis, pre-diabetes was an independent predictor for END (OR = 2.02; 95% CI 1.12–3.62; p = 0.02) and in-hospital death (OR = 3.12; 95% CI 1.06–9.09; p = 0.04). On the other hand, diabetes was a significant independent factor for poor long-term outcomes (OR = 1.75; 95% CI 1.09–2.78; p = 0.02) after correcting confounding factors. Conclusions Unlike diabetes, pre-diabetes can be an important predictor of short-term outcomes after AIS. However, a more detailed research is needed to specify the precise mechanisms through which pre-diabetes affects the prognosis of acute ischemic stroke. |
