Background: Stroke-associated pneumonia (SAP) is a common complication of cerebrovascular disease. The A2DS2 score has been used to predict the risk of SAP. However, hyperglycemia is not included in this scale. The purpose of the present study was to determine whether combining the A2DS2 scoring system and hyperglycemia can improve the predictive value of the conventional A2DS2 scale for SAP. Methods: This retrospective study enrolled 2,552 patients with acute ischemic stroke. The A2DS2 scores, fasting blood glucose level and blood glucose level on admission were collected. Regression analysis was used to identify the independent risk factors of SAP. ROC curve analysis was used to evaluate the specificity and sensitivity of the combined A2DS2 score and fasting hyperglycemia for predicting SAP. Results: Fasting hyperglycemia was an independent risk factor for SAP (OR=2.95; 95% confidence interval: 2.11-4.12; P<0.001). The area under curve of the combined A2DS2 score and fasting hyperglycemia was significantly higher than that of the A2DS2 score alone (0.814 vs. 0.793; P=0.020). Conclusion: Fasting hyperglycemia is an independent risk factor for predicting SAP. The predictive value of the modified A2DS2 score (combined A2DS2 score and fasting hyperglycemia) is superior to that of A2DS2 score.
