Background： The prevalence, presentation, management, and prognosis of coronary heart disease differ according to sex. Greater understanding on the differences between men and women with acute aortic dissection （AAD） is needed. We aimed to investigate whether sex disparities are found in patients with AAD, and to study sex differences in complications, mortality in-hospital, and tong-term. Methods： We included 884 patients enrolled in our institute between June 2002 and May 2016. Considering psychosocial factors, treatments, and the outcomes in men versus those in women with AAD, we explored the association of sex with psychosocial characteristics and mortality risk. For categorical variables, significant differences between groups were assessed with the Chi-square test or Fisher＇s exact test, and continuous parameters were assessed with Student＇s t-test. Univariate and stratified survival statistics were computed using Kaplan-Meier analysis. Results： A total of 884 patients （76.1% male, mean age 51.4 ± 11.8 years） were inchidcd in this study. There were fewer current smokers in female compared with male （ 17.5% vs. 67.2%,χ^2= 160.06, P〈 0.05）. The percentage of men who reported regular alcohol consumption was significantly higher than that in women （40.6% vs. 3.8%, χ^2== 100.18, P 〈 0.05）. About 6.2% （55 of 884） of patients with AAD died before vascular or endovascular surgery was performed, 34.4% （304 of 884） of patients underwent surgical procedures, and 52.7% （466 of 884） and 12.8% （113 of 884） of patients received endovascular treatment and medication, Postoperative mortality similar （6.0% vs. 5.6%, respectively, χ^2= 0.03, P = 0.91） between men and women. Follow-up was completed in 653 of 829 patients （78.8%）. Adjustment for age, history of coronary disease, hypertension, smoking and drinking, Type A and use of beta-blocker, angiotensin II receptor blockers, angiotensin converting enzyme （ACE） inhibitor, calcium-channel blockers and statins by multivariate logistic regression analysis suggested that age （odds ratios [ORs], 1.04; 95% confidence interval [CI], 1.01-1.07; P 〈 0.05）, using of calcium-channel blockers （OR, 0.37： 95% CI, 0.18-0.74; P 〈 0.05）, at discharge were independent predictors of late mortality, ACE inhibitors （OR, 1.91： 95% CI, 1.03-3.54： P = 0.04） was independent risk factor of late mortality.Conclusions： In Chinese with AAD, sex is not independently associated with long-term clinical outcomes. Age, the intake of calcium-channel blockers at discharge might help to improve long-term otitcomes.
