Serum retinol‐binding protein 4 as a predictor of cardiovascular events in elderly patients with chronic heart failure

Aims RBP4 is an adipokine with adverse effects on cardiovascular system. Increased circulating retinol‐binding protein 4 (RBP4) has been linked to chronic heart failure (CHF). However, whether elevated RBP4 is correlated with a poor prognosis in elderly patients with CHF remains unclear. The aim of this study was to evaluate the prognostic value of serum RBP4 in elderly patients with CHF. Methods and results We enrolled 934 consecutive elderly...
