Factors affecting acute aortic dissection mortality: A multicentre cohort study.

ABSTRACT:

Background

Acute aortic dissection (AAD) is an emergency associated with high mortality. Timely diagnosis is challenging, and delays may affect patient outcomes. We aimed to identify clinical and temporal factors associated with mortality after AAD.

Methodology

We performed a retrospective cohort study across four tertiary hospitals of type A and type B AADs diagnosed over a 20-year period. The outcomes of the study were in-hospital mortality, 30-day mortality, and mid-term (6-month) mortality. Univariate linear and bivariate logistic regression analyses were conducted to evaluate the relationship between mortality and demographic and clinical factors.

Results

The study included 149 AAD patients. Of these, 103 (69.1 %) were Stanford type A and 46 (30.9 %) Stanford typ
