Abstract:

Objective To investigated the changes of angiopoietin-like protein 2(Angptl2) in patients with arteriosclerotic occlusion (ASO). Methods A total of 140 subjects including 75 ASO patients (ASO group) and 65 healthy subjects (control group) were enrolled in this study. Angptl2 and adiponectin were evaluated by using enzyme-linked immunosorbent assay. Biochemical data and high sensitive C reactive protein were measured and recorded as well. Results Compared to the control group,the ASO group presented with significantly higher level of plasma Angptl2 [(13.55±9.17) μg/L vs. (9.04±4.79) μg/L,P=0.010]. Plasma Angptl2 level of critical limb ischemia subjects was significantly higher than that of intermittent claudication subjects [(17.01±10.20)μg/L vs. (10.53±6.97) μg/L,P=0.003]. The best diagnostic cutoff value of Angptl2 was 13.67 μg/L,with a sensitivity of 60.34% and a specificity of 81.25%. In addition,type 2 diabetes mellitus patients with ASO exhibited significantly higher serum Angptl2 levels [(18.67±9.84)μg/L] than those without ASO [(13.01±3.47) μg/L] (P=0.021). In ASO group,serum Angptl2 levels were negatively correlated with ankle brachial index (r=-0.244,P=0.035). Conclusion The plasma level of Angptl2 increases in ASO patients. Its level is remarkably increased when the disease progressions to critical limb ischemia. Angptl2 can be a potential biological marker of disease progression.
