Clinical Trial Summary
Type A acute aortic dissection (TA-AAD) patients are prone to life-threatening complications
and death during the acute phase. Currently, little evidence is available with regards to the
relationship between eosinophils (EOS) and TA-AAD.
A total of 274 patients with TA-AAD were eligible for inclusion and 54 patients deceased
within 1 month following surgery. Multivariate regression analysis, the general linear model
repeated-measures ANOVA analysis (corrected by Greenhouse-Geisser test), receiver-operating
characteristics (ROC) curves and a Kaplan-Meier curve were applied for statistical analysis.
Description:
For this study, 274 patients with TA-AAD admitted into our hospital between February 2019 and
July 2021 were enrolled retrospectively. A total of 54 patients deceased unfortunately within
1 month following surgery. We compared baseline sociodemographic, clinical, and functional
status based on the main outcome using t tests or Mann-Whitney U test for continuous data and
χ2 or Fisher's exact tests for categorical data. Continuous variables were expressed as mean
SD median depending on the normality of distribution, and categorical variables were
expressed as absolute number along with their percentages and compared using the chi-square
test. Multivariate regression analysis was applied to assess the association between EOS and
1-month mortality in an unadjusted model, in an age-, sex-, Body mass index (BMI)-adjusted
model (model 2), adjusted for age, sex, BMI, systolic blood pressure (SBP), diastolic blood
pressure (DBP) and mean arterial pressure (MAP) (model 3), and further adjusting for age,
sex, BMI, SBP, DBP, MAP, heart rate (HR), diabetes, stroke and hyperlipidemia (model 4). In
addition, the general linear model repeated-measures ANOVA analysis (Corrected by
Greenhouse-Geisser test in nonspherical cases) was used to compare preoperative EOS and
postoperative eight-days EOS. For prognostic analysis, receiver-operating characteristics
(ROC) curves were used to determine the optimal cutoff of EOS at different points and the
time of postoperative EOS to return to normal levels for the prognostic events. A
Kaplan-Meier curve was then applied to compare the prognosis between the 2 subgroups based on
the predictive threshold. A P value<0.05 was regarded as statistically significant for all
statistical tests.
