ABSTRACT

Objective: The objective is to expose the cardiovascular alterations in patients diagnosed with pediatric inflammatory multisystem syndrome (PIMS) associated with COVID-19 during the SARS-CoV-2 pandemic, in order to understand the disease, its evolution, and optimal management upon diagnosis. Method: Retrospective, observational, cross-sectional analytical study of patients diagnosed with PIMS according to the criteria of the World Health Organization at the National Institute of Pediatrics, from March 2020 to December 2021. Results: During the study period, 77 patients with PIMS were diagnosed. The results showed correlation between the shock state and alteration of laboratory markers (platelets 144217.29 ± 139321.6 µL [p < 0.001], procalcitonin 27.37 ± 38.37 ng/ml [p = 0.05] and ferritin 1937.87 ± 2562.63 [p < 0.001]). The ventricular function in patients with shock was significantly lower compared to those without shock (49.6 ± 9.1% vs. 58.1 ± 8.4 %; t-Student p < 0.001), as well as injury to the left coronary artery (p = 0.02). There is a correlation between NT-proBNP and ventricular dysfunction (Kruskal-Wallis p = 0.007). Statistical significance was found in the association between death, elevation of inflammatory markers and ventricular dysfunction (p < 0.001). Conclusions: The cardiovascular alterations observed, in order of frequency, were pericardial effusion (25.7%), myocarditis (15%), mild ventricular dysfunction (13.5%) and small coronary aneurysm with predominance of the left coronary artery and the anterior descending one.


Objetivo: Exponer las alteraciones cardiovasculares en los pacientes diagnosticados con síndrome inflamatorio multisistémico pediátrico (PIMS) asociado a COVID-19 durante la pandemia por SARS-CoV-2 con el fin de comprender la enfermedad, su evolución y el manejo óptimo al diagnóstico. Método: Estudio retrospectivo, observacional, transversal y analítico de pacientes con diagnóstico de PIMS de acuerdo con los criterios de la Organización Mundial de la Salud en el Instituto Nacional de Pediatría, de marzo de 2020 a diciembre de 2021. Resultados: Durante el periodo de estudio se diagnosticaron 77 pacientes con PIMS. Los resultados demostraron una correlación entre el estado de choque y la alteración de los marcadores de laboratorio (plaquetas 144217.29 ± 139321.6 µl [p < 0.001], procalcitonina 27.37 ± 38.37 ng/ml [p = 0.05] y ferritina 1937.87 ± 2562.63 [p < 0.001]). La función ventricular en los pacientes con choque se registró significativamente menor en comparación con aquellos sin choque (49.6 ± 9.1 % vs. 58.1 ± 8.4 %; t de Student p < 0.001), así como lesión en la arteria coronaria izquierda (p = 0.02). Existe una correlación entre el NT-proBNP y la disfunción ventricular (Kruskal-Wallis p = 0.007). Se encontró significancia estadística en la asociación entre fallecimiento, elevación de los marcadores inflamatorios y disfunción ventricular (p < 0.001). Conclusiones: Las alteraciones cardiovasculares observadas fueron, en orden de frecuencia, derrame pericárdico (25.7%), miocarditis (15%), disfunción ventricular leve (13.5%) y aneurisma pequeño coronario con predominio de la arteria coronaria izquierda y la descendente anterior.
