The Relationship between Blood Groups and Aortic Dissection.

Abstract

Plenty of diseases have been found having associations with blood types, especially cardiovascular diseases. The purpose of this study was to clarify whether there is a relationship between blood groups and acute aortic dissection. We also further studied the distribution of blood groups in different types of acute aortic dissection. A total of 291 patients diagnosed with acute aortic dissection from 2011 to 2018 were enrolled and analyzed retrospectively in this study. The control group consisted of 582 patients who received plastic surgery at West China hospital from 2011 to 2018. First, we analyzed the distribution of blood groups between the study group and the control group, including the ABO, Rh, O and non-O groups. Then, we further divided the study group into two groups by the type of acute aortic dissection to determine if there was difference in blood groups between the two types of acute aortic dissection. The analysis of the distribution of ABO blood groups (p = 0.302) and Rh blood groups (p = 0.502) did not reveal statistically significant differences. There were no statistically significant differences in the distributions of ABO blood groups and Rh blood groups in different types of acute aortic dissection. Our study did not prove the incidence of acute aortic dissection, or the type of acute aortic dissection had a relationship with common blood groups.
