Introduction: Dilated cardiomyopathy (DCM) is a pathology that affects the left ventricle resulting in high morbidity and mortality. It is the most common clinical form of cardiomyopathy in the pediatric population, although it is difficult to diagnose due to late treatment. Objective: To identify the death profile of pediatric patients with IDCD in Brazil. Method: This is an epidemiological, observational, analytical, cross-sectional study with data from the Hospital Admission System (SIH-DATASUS) from 2018 to 2020. The study population consisted of 678 children, aged 0 to 19 years , with the variables used: sex, age group, nationality, ethnicity, type of hospitalization, place of hospitalization, legal nature, management, ICU stay, specialty, diagnosis and treatment. A bivariate analysis was performed using the Mantel-Haenszel chi-square method, considering the relative risk of death and its respective 95% confidence interval as a measure of association. in search. Results: The prevalence was female, over 5 years old, Brazilian, of brown ethnicity and had no comorbidities. We highlight the higher mortality rate in the specialty of pediatrics, in children younger than 5 years old, with comorbidities and who needed to be admitted to the ICU. Conclusion: Children under 5 years old, especially those with comorbidities, especially heart failure, should be analyzed with greater caution and that health service professionals can monitor them rigorously and intervene early, in order to avoid possible negative outcomes such as to evolve unfavorably and/or to death.
