To investigate the risk factors associated with death in patients with acute aortic dissection (AAD).

Thirty-three AAD patients in Henan Hongli Hospital from were divided into survival group (n=18) and death group (n=15) from January 2016 to December 2018 according to their survival during hospitalization. The clinical data of the two groups (general information, past medical history, symptoms and signs, auxiliary examination, Stanford classification) were compared between the two groups.

Shock, coma, aortic reflux, pericardial effusion, carotid artery and/or brachiocephalic trunk involvement were more common in the death group than those in the survival group (P<0.05). The blood pressure (right systolic pressure, bilateral diastolic pressure) of the death group was lower than that of the survival group, with statistical significance (P<0.05). The mortality rate of type A AD of Stanford classification was higher than that of type B AD in death group, and the difference was statistically significant (P<0.01).

The mortality rate of type A AD patients is higher. The patients with type A AD complicated with shock, coma, and other complications such as aortic reflux, pericardial effusion, carotid artery and/or brachiocephalic trunk involvement are positively correlated with the mortality rate, which should be paid more attention to.
