Alcohol use disorder is associated with a lower risk of in-hospital mortality in type A aortic dissection repair: a population-based study of National Inpatient Sample from 2015-2020.

AUD patients had a lower risk of in-hospital mortality but a higher rate of respiratory complications and a longer LOS. These findings can provide insights into preoperative risk stratification of these patients. Nonetheless, reasons underlying the lower mortality rate in AUD patients and their long-term prognosis require further investigation.
