Cardiorenal anemia syndrome as a prognosticator for death in heart failure

Abstract

Anemia and chronic kidney disease are common in patients with heart failure (HF) and are associated with adverse outcomes. We analyzed the effect of cardiorenal anemia (CRA) syndrome, defined as anemia (hemoglobin <130 g/L for men, <120 g/L for women) and stage 3 or greater chronic kidney disease (estimated glomerular filtration rate <60 ml/min/1.73 m2), in outpatients with HF. Consecutive patients with HF were prospectively enrolled from 2000 to 2005 (n = 748). The baseline clinical characteristics, pathology test results, and medication use were compared between those with and without CRA syndrome. The primary end point was all-cause mortality. The mean follow-up was 2.5 ± 1.6 years, with ..
