title: Clinical features of acute aortic dissection from the Registry of Aortic Dissection in China.
abstract: OBJECTIVE
  To establish a systematic registry of aortic dissection in China, assess the clinical features of Chinese patients with acute aortic dissection (AAD), and compare our results with the data published by the International Registry of Acute Aortic Dissection (IRAD).
  
  
  METHODS
  We established the first Registry of Aortic Dissection in China (Sino-RAD) in 2011. Then we evaluated 1003 patients with AAD in Sino-RAD and compared our results with those reported by IRAD.
  
  
  RESULTS
  Compared with IRAD, the patients with AAD in Sino-RAD were significantly younger. Also, the ratio of male patients in Sino-RAD was significantly greater for the total cohort and the type A and B cohorts. The overall in-hospital mortality was 10.3% in Sino-RAD. For type A dissection, more patients in Sino-RAD received medical treatment and fewer received surgical treatment. The overall mortality, mortality of medical treatment, and mortality of surgical treatment was lower in Sino-RAD. In type B dissection, fewer patients in Sino-RAD received medical and surgical treatment and more received endovascular treatment.
  
  
  CONCLUSIONS
  The first Sino-RAD, including 15 large cardiovascular centers throughout China, was established. Our data were compared with those reported by IRAD. We found that, compared with Western populations, Chinese patients with AAD showed 6 differences, including earlier onset, more male patients, a low incidence of hypertension, a low incidence of chest pain, a high incidence of back pain, great differences in the choice of therapeutic strategies, and relatively low in-hospital mortality.
