Gender Difference is Associated with Short-Term Outcomes in Non-Surgically Managed Acute Aortic Dissection Patients...

The management of acute aortic dissection (AAD) has improved; however, the outcomes related to different gender with short-term outcomes in non-surgically managed AAD with hypertension are still limited. Our objective was to explore gender-differences in association with short-term outcomes of patients comorbid with hypertension in non-surgically managed AAD.

This is an observational retrospective single-center cohort. We analyzed the data from the Second Xiangya Hospital of Central South University (2014-2018). The data on demographics, clinical presentation, chronic comorbidities, laboratory testing, imaging studies, and treatment were analyzed for all patients. Univariate and multiple analyses were used to test gender-difference associated with short-term outcomes of patients with hypertension in non-surgically managed AAD.

In total, 288 patients were enrolled in this study, of whom 238 (82.63%) were male and 50 (17.37%) were females. About 74% of female patients were dead in-hospital, which was more than male patients (56.3%). Female patients with diabetes mellitus were more than male patients (14% vs 2.94%), while male patients with smoking were significant higher than female patients (36.55% vs 8%). In the full model (model 3), after adjusting for confounding variables, the female AAD patients were more likely to have worse short-term outcomes (OR=3.60, 95% CI=1.41 to 9.60).

Female patients were more likely to have worse outcomes in non-surgically managed AAD patients with hypertension. Large numbers of investigations are required to further explore this relationship.
