Cross-sectional Study of Prevalence Rate of Abdominal Aortic Aneurysm in OSAHS Patients From BTCH

This study explore AAA prevalence in OSAHS patients by ultrasound screening and try to analysis risk factors of AAA in OSAHS patients.

Abdominal aortic aneurysm (AAA) is an extremely high mortality disease, and ultrasound has been recommended for the screening of AAA, which is highly sensitive and specific. Studies have shown that screening for AAA in the population can significantly reduce deaths from ruptured abdominal aortic aneurysms. However, those study mainly focus on cardiovascular disease patients or general population, no previous study target on obstructive sleep apnea hypopnea syndrome (OSAHS) population. Retrospective studies show that the incidence of apnea syndrome in patients with abdominal aortic aneurysm is higher than that in the control group, which suggests that OSAHS may be one of the causes of abdominal aortic aneurysm. At present, there is no relevant research on the screening of AAA in OSAHS population. The main objective of this study was to screen the prevalence of AAA in OSAHS population by a cross-sectional study.
