Abstract

Introduction and objectives: There is a great variability in the prevalence of anemia in heart failure (HF) according to cohort based studies where the majority of patients have depressed left ventricular ejection fraction (LVEF). Our study has aimed to evaluate the prevalence of anemia in HF within the usual hospital clinical practice.

Methods: An initial analysis was made of a prospective cohort of inpatients with HF admitted during 3 months in 15 Internal Medicine Services including all health system levels. We used the World Health Organization (WHO) criteria to define anemia (hemoglobin [Hb] < 12 g/l in women and < 13 g/l in men) and a value > or = 45% as preserved LVEF.

Results: A total of 391 patients with an average age of 77.9 +/- 9.4; 239 women (61.1%). The 52.7% of the cases had anemia. Regarding multiple associated factors to anemia in the bivariant analysis, the regression model indicated the following variables: preserved LVEF (odds ratio [OR] 3.03), not being HF debut (OR 1.85), glomerular filtration (OR 0.97), functional class III-IV of the New York Heart Association (NYHA) (OR 0.53), arterial vascular disease (OR 0.41), antiaggregant treatment (OR 0.56) and treatment with nitrites (OR 0.48).

Conclusion: Prevalence of anemia in HF is very high in usual clinical practice, that most frequently occurs in subjects with preserved LVEF.
