Background: Secreted frizzled-related protein 5 (SFRP5) is a novel adipokine that has been found to be closely associated with metabolic and cardiovascular diseases. We investigated serum SFRP5 levels during the acute phase and their predictive value for the prognosis of acute aortic dissection (AAD). Methods: In total, 152 AAD patients and 164 controls were enrolled in this study. Serum SFRP5 levels were measured using an enzyme-linked immunosorbent assay (ELISA). AAD patients were divided into high-SFRP5 and low-SFRP5 groups based on the optimal cutoff value and followed up for prognosis. The primary endpoint was all-cause mortality, and the secondary endpoint focused on AAD-related events (including AAD-related mortality and unplanned reoperations). Results: Serum SFRP5 levels were significantly higher in AAD patients than in non-AAD controls, regardless of whether they had Stanford type A or B AD. Multivariate logistic regression analysis revealed an independent association between SFRP5 and the presence of AAD (adjusted OR 1.267, 95 % CI 1.152–1.394; p < 0.001). The receiver operating characteristic curve demonstrated that the optimal cutoff value for SFRP5 to predict the presence of AAD was 10.26 ng/mL (AUC 0.7241, sensitivity 49.34 %, specificity 87.20 %). Notably, serum SFRP5 levels of patients in the death group were significantly higher than those in the survival group. Compared with patients in the low-SFRP5 group, those in the high-SFRP5 group exhibited a significantly increased risk of all-cause mortality (HR 9.540, 95 % CI 2.803–32.473; p < 0.001) and AAD-related events (HR 6.915, 95 % CI 2.361–20.254; p < 0.001) during the follow-up period. Conclusion: Serum SFRP5 levels were significantly elevated in the acute phase of AAD, and high serum SFRP5 levels were independently associated with poor AAD prognosis. These results suggest that serum SFRP5 level during the acute phase may be an effective biomarker and therapeutic target for the prognosis of AAD.
