Abstract: Objective To explore the correlation between glycemic variability and neurological impairment in patients with acute ischemic stroke (AIS) complicated with diabetes mellitus. Methods A total of 125 patients with AIS and diabetes mellitus were selected. The general clinical data at baseline were recorded, and the National Institutes of Health Stroke Scale (NIHSS) was scored at admission and discharge respectively, and the modified Rankin Scale (mRS) score was recorded 1 month after discharge to evaluate neurological changes and disability after stroke. According to whether the NIHSS score worsened or not, the patients were divided into a non-deterioration group and a deterioration group, and the baseline data and glycemic variability parameters were compared between the two groups. Logistic regression was used to analyze the possible factors affecting neurological deterioration, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of blood glucose variability indicators for neurological deterioration. Results There was no statistical difference in baseline clinical data between the two groups, but a statistical differences in blood glucose variability parameters with mean amplitude of glycemic excursions(MAGE) and largest amplitude of glycemic excursions(LAGE) (P<0.05). Binary Logistic regression analysis showed that time in range(TIR) (OR=0.937, P<0.001), MAGE (OR =1.360, P=0.024), and LAGE (OR=1.364, P=0.015) were the risk factors for worsening NIHSS score. Ordinal multivariate Logistic regression analysis showed that MEAN (OR=1.208, P=0.033), MAGE (OR=1.206, P=0.040) and admission fasting blood glucose (OR=1.182, P=0.016) were the risk factors affecting the mRS score. The ROC curve showed that the area under the curve (AUC) of TIR for predicting deterioration was 0.781 (95% CI:0.699-0.862, P<0.001), the sensitivity was 82.6%, the specificity was 60.8%, and the best cut-off value was 41.3%. Conclusion The glycemic variability indicators represented by TIR and others are related factors that may indicate the deterioration of neurological function in patients with AIS and diabetes mellitus.
