Background: The present study aimed to clarify the impact of the 2020
COVID-19 pandemic on emergency management of acute type A aortic dissection.
Methods: We consecutively enrolled 337 acute type A aortic dissection
(ATAAD) patients at emergency room in Fuwai Hospital (Beijing, China) from
January to June during the 2020 COVID-19 epidemic (n = 148) and the same period
in 2019 as the historical control (n = 189). The primary outcome was defined as
in-hospital death. Other outcomes included automatic discharge during emergency
admission. The factors with significant differences before and after the epidemic
were compared and analyzed by stages with the study endpoint to clarify their
changes in different stages of the epidemic. Results: There was no
significant difference in in-hospital mortality (35 (20.5%) vs. 23 (17.4%),
p = 0.472). Compared with year 2019, proportion of patients receiving
surgical treatment decreased significantly (74 (50.0%) vs. 129 (68.25%),
