Admission Values of Plasma Biomarkers Predict the Short-Term Outcomes in Acute Aortic Dissection.

BACKGROUND AND AIMS Acute aortic dissection (AAD) is an emergency disease with high misdiagnosis rate and mortality. The aim of the present study is to explore the impact of blood-related biomarkers, specifically D-dimer, on in-hospital outcomes of patients with AAD. MATERIALS AND METHODS A total of 345 patients in our hospital from December 2013 to April 2017 were included. The cutoff value for D-dimer and LDL-C were set as 5.9mg/l and 1.45 mg/l, respectively. The univariate and multivariate logistic regression models were used to identify the independently prognostic predictors. RESULTS The results showed that patients with type A AAD had higher risk of in-hospital mortality compared with those with type B disease. Moreover, results revealed the type A AAD (OR 6.382, 95%CI: 2.423 to 16.812), D-dimer (OR 2.160, 95%CI: 1.072 to 4.350), and LDL-C (OR 0.373, 95%CI: 0.148 to 0.940) were independently associated with in-hospital mortality. Subgroup analysis suggested that D-dimer (OR 2.295, 95%CI: 1.140 to 4.622) was an independently prognostic factor in type A AAD. CONCLUSION In summary, D-dimer ≥5.9 mg/L and type A AAD were independently associated with in-hospital mortality in AAD patients. Moreover, subgroup analysis proved that the elevated D-dimer was related to poor prognosis in type A AAD.
