Objective Admission D-dimer and C-reactive protein (CRP) values have been reported to predict the short-term outcomes in acute aortic dissection (AAD). However, the association between D-dimer values and the long-term outcomes has not been investigated.

Methods The primary endpoints included events determined to be all-cause death, recurrence of aortic dissection, aortic rupture, and surgical intervention for the aortic aneurysm following the first hospital discharge. We performed a receiver operating characteristic analysis and determined the optimal cut-off levels of admission D-dimer, admission CRP and peak CRP values in terms of the sensitivity and specificity for predicting the presence of events. Using the optimal cut-off values, we performed a multiple Cox analysis and investigated the hazard ratio of admission D-dimer, admission CRP and peak CRP.

Patients We retrospectively identified 173 AAD patients hospitalized between January 2005 and December 2013.

Results A multiple Cox regression analysis revealed that the hazard ratios were 3.4 for admission D-dimer [95% Confidence Interval (CI) 1.5 to 7.3, p=0.004] and 2.7 for admission CRP (95% CI 1.2 to 5.5, p=0.014).

Conclusion Admission D-dimer and CRP values may predict the long-term outcomes in AAD. Moreover, admission D-dimer values may be a valuable marker to predict not only the short-term outcomes, but also the long-term outcomes in AAD.
