title: [Comparative study in clinical features and managements of aortic dissection between Chinese and Caucasians].
abstract: OBJECTIVE
  To explore differences in the clinical characteristics, treatment methods and progness of Chinese (Han) and Western populations (Caucasia) aortic dissection (aortic dissection, AD) patients.
  
  
  METHODS
  According to the requirements of systematic review, We searched MEDLINE (1980-2014), Emabse (1980-2014), CBM (1980-2014) and CNKI (1980-2014) database overall, the meta-analyses were performed through STATA 12.0.
  
  
  RESULTS
  A total of 6 697 Stanford A AD and 3 381 Stanford B AD Caucasian patients and 850 Standford A AD and 4 745 Stanford B AD Chinese Han patients were deemed eligible. It showed that average age of Han patients was lower, the proportion of Han group was 84.5%, while Cuacasian group was 66.9%, the differences were statistically significant (χ² = 365.37, P < 0.01). Han patients with history of smoking and that of coronarty heart diseases accounted for 53.0%, 13.8% separately, which were higher than those of Caucasian group, the differences were also statistically significant (χ² = 264.23, 68.417, P < 0.01).Besides these,the proportions of Han Stanford B AD patients who had hypertension, diabetes were also statistically significant higher than Caucasian group (χ² = 264.23, 68.417, P < 0.01). The Chinese group was more likely to appear nervous system and heart damages before surgery while the Caucasian group mostly appeared kidney and peripheral vascular damages. In the choice of treatment, the number of open surgery patients was significantly higher than that in Caucasian group. Domestic acute AD patients were more likely to accept TEVAR. The 30-day mortality of Chinese Han group in Stanford B was 2.4%, while Caucasians' mortality was 11.2%, the differences were statistically significant (χ² = 142.96, P < 0.01).
  
  
  CONCLUSIONS
  The incidence of Chinese AD patients who are younger with more basic diseases has been increasing gradually, Although the 30-day mortality and complications rates of Chinese patients accepting early surgery intervention are lower than Caucasians, due to the less available data, large sample researches and further long-term follow-up will be needed.
