Objective To explore the differences in the characteristics of acute aortic dissection (AAD) among less and more economically developed countries with various cultures and races. Data sources Reports from the International Registry of Acute Aortic Dissection (IRAD) and the mainland of China (MC) were collected by searching the PubMed Database and the Chinese Journal Full-text Database from January 2000 to March 2009. Study selection Those reports from IRAD and MC containing larger numbers of cases and complete patients' information were selected, which focused on concrete issues of diagnosing or managing AAD were excluded if they were not able to reflect the overall characteristics of this condition. And the data from the article containing the largest number oatients reDorted bv the same medical center in MC were taken into statistics. 展开更多
