ESCURRA, Lizzie e TORRES DE TABOADA, Estela. Frequency of iron deficiency in patients with heart failure. Rev. Nac. (Itauguá) [online]. 2019, vol.11, n.1, pp.68-79. ISSN 2072-8174. https://doi.org/10.18004/rdn2019.0011.01.068-079.
Introduction:
iron deficiency is a comorbidity in patients with heart failure with can cause serious clinical consequences and generate poor prognosis.
Objectives:
to determine the frequency of iron deficiency anemia in patients hospitalized with heart failure and to describe their demographic and clinical characteristics.
Methodology:
observational, descriptive, prospective, cross-sectional. Were included male and female patients, older than 18 years of age, with heart failure, admitted to the National Hospital (Itauguá, Paraguay) in the years 2017-2018. Clinical and laboratory variables were measured. Iron-deficiency anemia was considered in patients with hemoglobin value ≤ 13 g / dL in men and ≤ 12 g / dL in women with ferritin <100 μg / L.
Results:
152 patients were included, with a mean age of 68 ± 14 years being 57% males. Between comorbidities, arterial hypertension was prevalent (95%). 72% of subjects with iron deficiency anemia were found, the frequency being higher in grades II and III of the NYHA functional classification
Conclusion:
The frequency of iron deficiency anemia in patients with HF was 72% and was prevalent in males with functional class II-III. The most frequent comorbidity was arterial hypertension.
