Time-dependent changes of plasma inflammatory biomarkers in type A aortic dissection patients without optimal medical management

To investigate the time-dependent changes in plasma levels of interleukin-6, C-reactive protein, and tumor necrosis factor-α in patients with type A aortic dissection (TAAD) who received unoptimal medical management since the onset of dissections. Plasma levels of interleukin-6, C-reactive protein, and tumor necrosis factor-α were detected by ELISA and immuno-turbidimetric assay in 92 TAAD patients at hospital admission. Blood samples from 78 patients with uncontrolled hypertension and 82 healthy volunteers were also analyzed as controls. The occurrence of TAAD-related complication and its relationship with the plasma levels of these inflammatory biomarkers was also investigated. The concentrations of inflammatory mediators were significant higher in TAAD than those in the uncontrolled hypertension and the healthy group. The time to peak plasma level of IL-6.and TNF-α was shorter than that of CRP in TAAD group. In the TAAD group, 51 patients suffered TAAD-related complications, and their plasma level of CRP was significantly higher than that in patients without TAAD-related complications (94.5 ± 58.8 mg/L versus 47.4 ± 47.8 mg/L, p
