Methods The levels of serum Ang-2, N-terminal pro-B-type natriuretic peptide (NT-proBNP) and left ventricular ejection fraction (LVEF) were detected in 113 patients with CHF, who were divided into four groups according to New York Heart Association (NYHA: class Ⅰ, n=32; Ⅱ, n=30; Ⅲ, n=26; Ⅳ, n=25). Another 20 healthy volunteers for physical check-up were chosen as the control group. Results With the change of cardiac function (from Ⅰ to Ⅳ), the levels of plasma Ang-2 and NT-proBNP were increased significantly (P<0.05). The level of serum Ang-2 was positively correlated with NT-proBNP (r=0.774, P<0.001), but negatively correlated with left ventricular ejection fraction (r=-0.725, P<0.001). Conclusion The level of serum Ang-2 has a significant correlation with the severity of heart failure. Ang-2 is expected to be used to predict and evaluate the severity of CHF %K 慢性心力衰竭 %K 血管生成素-2 %K N-末端脑钠肽前体 %K 左室射血分数 %K 相关性分析< %K br> %K chronic heart failure %K angiopoietin-2 %K N-terminal pro-B-type natriuretic peptide %K left ventricular ejection fraction %K correlation analysis %U http://yxxb.xjtu.edu.cn//oa/darticle.aspx?type=view&id=201603007
