Abstract

Background— Anemia is known to be a prognostic marker for patients with heart failure. However, little is known about the prognostic value of changes in hemoglobin (Hgb) over time or about the causes of anemia. Methods and Results— Retrospective analysis of Valsartan Heart Failure Trial data indicated that the quartile of patients with the biggest average decrease in Hgb over 12 months (from 14.2 to 12.6 g/dL) had significantly ( P ≤0.01) increased risk of subsequent hospitalization (hazard ratio [HR], 1.47), morbid events (HR, 1.41), and death (HR, 1.6) compared with the quartile that exhibited little change in Hgb over 12 months (from 13.7 to 13.8 g/dL). Increasing Hgb was significantly associated with lower mortality in patients with (HR, 0.78) and without (HR, 0.79) anemia at baseline. Anemia at baseline and the changes in Hgb were independently associated with serum albumin, blood pressure, glomerular filtration rate, B-type natriuretic peptide, and C-reactive protein. Lack of anemia at baseline and increases in Hgb over 12 months were not associated with smaller left ventricular diameters or higher ejection fractions. Conclusions— Changes in Hgb over 12 months were inversely associated with subsequent risk of mortality and morbidity, independently of the effects of baseline anemia and other important predictors. Several factors were independently related to anemia at baseline and changes in Hgb, suggesting multiple causes of anemia in patients with heart failure. These findings raise important questions about the optimal level of Hgb in patients with moderate to severe heart failure and how to achieve them.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
