S100A1 as a potential biomarker for the diagnosis of patients with acute aortic dissection

Objective Acute aortic dissection (AAD) is a common life-threatening cardiovascular disease. This retrospective study was conducted to analyze the plasma concentration of S100A1 and its diagnostic value for AAD through receiver operating characteristic (ROC) curve and logistic regression analyses. Methods Seventy-eight patients with AAD and 77 healthy controls were included, and the relevant clinical data for each group were collected. According to the Stanford classification, the AAD patients were divided into types A and B. The plasma levels of S100A1, D-dimer, hypersensitive C-reactive protein, and cardiac troponin T were detected by enzyme-linked immunosorbent assays. Results The S100A1 concentrations in the healthy control, Stanford A, and Stanford B groups were 0.7 +/- 0.6, 4.9 +/- 2.6, and 3.5 +/- 2.2 ng/mL, respectively. The concentration of S100A1 was increased in patients with AAD complicated with aortic regurgitation, pericardial effusion, or in-hospital death. ROC curve analysis showed that the area under the curve was 0.89. Logistic regression analysis revealed that the S100A1 level was an important risk factor for the development of AAD. Conclusion Plasma S100A1 is significantly elevated in patients with AAD, and its concentration has potential clinical value for diagnosing AAD.

Automated summary

This study investigated the plasma concentration of S100A1 in patients with Acute Aortic Dissection (AAD) and its diagnostic value. The results indicated that S100A1 levels are significantly elevated in AAD patients and have potential clinical value for diagnosing the disease. Additionally, S100A1 was identified as an important risk factor for the development of AAD.
