Previous studies have demonstrated that admission hyperglycemia is a predictor of mortality and poor prognosis in patients with cardiovascular diseases, such as acute myocardial infarction. However, the prognostic value of admission hyperglycemia in patients with acute type A aortic dissection (AAAD) has never been explored. To clarify the association between hyperglycemia and in-hospital outcomes, we retrospectively analyzed 734 patients with AAAD. The interest endpoints were in-hospital mortality rate, the duration of intensive care unit and hospital stays, the occurrence of prolonged mechanical ventilation (PMV), and other complications. All patients were divided into the normal blood glucose group (≤140 mg/dL) and hyperglycemia group (> 140 mg/ dL), to compare the in-hospital outcomes rate in the two groups. There were 531 (72.3%) patients with normal blood glucose levels and 203 (27.7%) patients with hyperglycemia. The in-hospital mortality rate was 21.1%, and no statistically significant differences were found between the two groups (20.3% versus 23.2%, P = 0.403). PMV is the most frequent postoperative complication, the incidence of which was significantly higher in the hyperglycemia group than in the normal blood glucose group (59.6% versus 50.8%, P = 0.040). The logistic regression analysis revealed that hyperglycemia (odds ratio (OR): 1.492; 95% CI: 1.014 to 2.197; P = 0.042) was an independent risk factor for PMV after adjusting for confounding factors. Age (OR: 1.021; 95% CI: 1.006-1.037; P = 0.007) and body mass index (OR: 1.101; 95% CI: 1.051-1.153; P < 0.001) were also associated with PMV. In conclusion, our study showed for the first time that a strong correlation between admission hyperglycemia and increased postoperative PMV in patients with AAAD, but not with in-hospital mortality rate.
