Introduction: Heart failure is currently a global public health problem associated with significant morbidity and mortality. Iron deficiency is the most common nutritional deficiency in these patients, it contributes to both the clinical worsening and the left ventricular ejection fraction. It is important to study the relationship between both pathologies and treat this comorbidity to have better results. Objective: Determine if there is a relationship between iron deficiency and functional limitation and ejection fraction in heart failure at the Adolfo Guevara Velasco National Hospital, August - November 2023. Methodology: Quantitative, correlational, observational, prospective and crosssectional study. The sample was for convenience, a total of 100 patients participated, who met the inclusion criteria. Significance was calculated using the χ2 statistical test for bivariate analysis. Results: Of the 100 patients studied, the age group ≥ 60 years represented 70%, 52% were male and the type of medical care with the highest percentage was hospital (56%). Regarding the clinical evaluation of functional capacity (NYHA), classes III and IV were in a greater proportion (65%) compared to classes I and II (35%). Patients with reduced LVEF were the majority (52%), followed by preserved (33%) and slightly reduced (15%). Iron deficiency was determined according to serum ferritin, where 65% had it < 100 ng/ml (absolute iron deficiency), transferrin saturation was not counted for the diagnosis of functional ID. Hemoglobin was used as an indicator of advanced phase of iron deficiency, where 30% of all patients had this parameter below normal values. It was found that there is an association between iron deficiency and functional classification III and IV according to NYHA (p <0.001), likewise, there is an association between iron deficiency and reduced LVEF (p <0.001). Conclusions: There is a relationship between absolute iron deficiency and class III and IV functional limitations according to NYHA. There is also a relationship between absolute iron deficiency and reduced ejection fraction in patients with HF at the Adolfo Guevara Velasco National Hospital, August - November 2023.
