Objective:To investigate the prognostic value of left ventricular ejection fraction(LVEF)combined with angiogenin-2(Ang2)in chronic heart failure(CHF). Methods:LVEF and angiogenin-2 of 143 patients with chronic heart failure were measured from January 2010 to December 2012. The patients were followed up for one time every 3 months,and the follow-up period was 3 years. Cardiovascular death was considered as the end event. Logistic regression was used to analyze the risk factors for death in 3 years. ROC curv...
