Angiotensin II Pathway and Acute Lung Injury
Study Details
Study Description
Brief Summary
Acute type A aortic dissection is often accompanied by postoperative pulmonary complications, the cause of which is not fully understood.Angiotensin II is an important component of the renin-angiotensin system (RAS), which has been suggested to be involved in the development of aortic dissection and pulmonary inflammation.The purpose of this study was to investigate the role and mechanism of angiotensin II pathway in postoperative pulmonary complications after acute type A aortic dissection, and to provide reference for clinical application

Outcome Measures
Primary Outcome Measures
- The difference concentrations of Ang II,ACE2 and miR-145 in serum between patients with and without postoperative hypoxemia. [Within 24 hours after surgery]
Blood samples were taken within 24 hours after operation to detect the contents of Ang II, ACE2 and miR-145 in serum.
Secondary Outcome Measures
- The risk factors for postoperative hypoxemia in Stanford type A acute aortic dissection patients. [up to 60 days]
Basic characteristics, intraoperative details, biochemical parameters and outcome results were obtained, and blood was collected within 24 hours after surgery for the measurement of ANG II, sACE2 and mir-145 concentrations. Univariate analysis was first performed to identify the potential risk factors for postoperative hypoxemia. Multivariate logistic regression analysis was performed for factors with P < 0.05 or that were considered clinically important.
