[Change of Serum Angiopoietin-related Growth Factor in Patients with Abdominal Aortic Aneurysm and Its Clinical Significance].

To investigate the changes and value of plasma angiopoietin-related growth factor (AGF) in patients with abdominal aortic aneurysm (AAA).Serum AGF level was analyzed in 50 AAA patients and in 56 healthy subjects. AGF and adiponectin were quantified by enzyme-linked immunosorbent assay. Routine testing of blood biochemistry and high-sensitivity C-reactive protein were performed.The plasma AGF level was significantly higher in AAA patients than in the controls [(87.91±96.87) μg/L vs. (56.89±41.32) μg/L, P=0.040],while serum adiponectin level showed no significant difference between these two groups. The plasma AGF level in patients with an AAA>5 cm and those with AAA between 3 cm and 5 cm were (96.08±68.61) μg/L and (75.27±46.05) μg/L.Plasma AGF is highly expressed in AAA patients. Higher serum AGF level is associates with larger AAA. Thus, AGF may be a potential serum biomarker for AAA.
