Prevalencia de deficiencia de hierro en pacientes con insuficiencia cardíaca en el Hospital Teodoro Maldonado Carbo en los años 2017-2019.

Abstract

Objectives: Estimate iron deficiency prevalence in congestive heart failure inpatient record from Hospital Teodoro Maldonado Carbo during 2017-2019 years. Methods and materials: Retrospective and transversal study from congestive heart failure diagnosed patients. Data was filtered with inclusion and exclusion criteria before statistic analysis. Qualitative variables were analyzed with frequencies and percentages while quantitative variables were analyzed with mean and standard deviation. Results: There were 143 patients included. It was found that 34% of patients with heart failure fulfilled the criteria for iron deficiency, based on low serum iron. Ferritin was found normal or elevated in 96.94% of patients with iron deficiency. Average age of patients was 71.24-year-old. The 60.13% of patients had anemia from low hemoglobin. Anemia was more frequent in women (79%) than in men (47.05%) (p=0.000). Conclusions: Iron deficiency is a frequent comorbidity in patients with heart failure, but ferritin values seem to not be trustworthy biomarkers to study iron deficiency in patients with other diseases, for further studies are recommended. Patients over 55 years are the most affected from iron deficiency, so this is a late life stage comorbidity. Iron deficiency seems to tend to be more frequent in women than in men, but data was not conclusive.
