There is, however, no systemic investigation regarding the role of plasma C-reactive protein （CRP） and white blood cell （WBC） levels in predicting in-hospital clinical events of acute type AAD. Methods The levels of high-sensitivity CRP and WBC counts were systemically determined after admission in 36 patients with acute type A AD. The variations of plasma CRP and WBC levels in different time windows （admission, 1, 2, 3, 4, 6, 8 days） in patients with acute type AAD were analyzed between patients with events and without events. Results During hospitalization, five patients died, and increased levels of CRP and WBC were found in patients died with acute type A AD compared with patients survived （P 〈0.01, respectively）. Medical treatment may significantly decrease inflammatory response in survived patients with acute type A AD. Additionally, patients with complication of pleural effusion showed higher CRP and WBC levers （P=0.046, P=-0.018, respectively）. Lower WBC levels were found in survived patients treated medically （P=-0.001）. Moreover, mean CRP and WBC levels had positive correlations with aortic diameter （r=0.364, P--0.000; r=0.333, P=0.000, respectively） and age （r=0.270, P=0.000, respectively）, while negative correlations with the time from onset of symptoms to hospital admission （r= -0.229, P=0.000, r= -0.200, P=0.002, respectively）. Univariate analysis showed that age 〉65 years, CRP zl 2.05 rag/L, WBC 〉12.16×10^9/L, aortic diameter 〉48 mm, pleural effusion and diastolic blood pressure 〉105 mmHg were associated with hospital mortality. While CRP 〉12.05 mg/L, WBC ≥12.16×10^9/L, aortic diameter 〉48 mm were strongly associated with hospital mortality in multiple Logistic regression analysis.
