Study on the Correlation between Blood Glucose Level and Hospital Mortality in Acute Aortic Dissection Patients

BackgroundAcute aortic dissection (AAD) is more common in critically ill patients, and hyperglycemia is an adverse factor affecting the mortality of critically ill patients.ObjectiveTo investigate the correlation between admission blood glucose level and in-hospital mortality in patients with AAD.MethodsA retrospective analysis of the case data of non-diabetic AAD patients who underwent surgical treatment at the Fourth Hospital of Hebei Medical University from January 2015 to August 2020. According to admission blood glucose level, all cases were divided into: the hyperglycemia group (>7.8 mmol/L) and the normal blood glucose group (≤7.8 mmol/L) ; Cox proportional hazard modelwas used to evaluate the correlation between admission blood glucose and in-hospital mortality in AAD patients; Kaplan-Meier method was used to analyze the survival curve; ROC analysis was conducted to evaluate the predicting values of admission blood glucose for the in-hospital mortality in AAD patients; Cox regression model were perfor
