Significance of plasma D-dimer content in the differentiation between acute Stanford type A aortic dissection and non-ST-segment elevation myocardial infarction
Objective To analyze the difference of plasma D-dimer levels between patients with acute Stanford type A aortic dissection or non-ST-segment elevation myocardial infarction, and to explore the clinical significance of D-dimer in the differential diagnosis of the two. Methods Retrospective analysis of 107 patients with acute non-ST-segment elevation myocardial infarction and 104 patients with acute Stanford type A aortic dissection in the First Affiliated Hospital of Zhengzhou University. Comparing plasma D-dimer content in the two groups, the differential significance of plasma D-dimer content in acute Stanford type A aortic dissection was analyzed through ROC Curve analysis. Results The plasma D-dimer content in patients with acute Stanford type A aortic dissection was significantly higher than that in patients with non-ST-segment elevation myocardial infarction (P < 0.05). ROC curve analysis showed that plasma D-dimer content in the subjects of this study was of differential significance for the two diseases (P < 0.05). Conclusions Emergency detection of plasma D-dimer content has clinical significance in differentiating the two diseases. For patients with acute chest pain and increased D-dimer content, acute Stanford type A aortic dissection can be highly suspected when other general admission examinations are difficult to differentiate from acute non-ST-segment elevation myocardial infarction.
