Abstract
Objectives

It is known that COVID-19 has multisystemic effects. However, its early effects on muscle tissue have not been clearly elucidated. The aim of this study is to investigate early changes in the pectoral muscle in patients with COVID-19 infection.

Materials and methods

The pectoral muscle areas (PMA) and pectoral muscle index (PMI) of 139 patients diagnosed with COVID-19 were measured from chest CTs taken at the time of the first diagnosis and within 6 months after the diagnosis. The effect of the infection on the muscle area was investigated by evaluating whether there was a change between the two measurements. Lung involvement of the infection in the first CT was scored with the CT severity score (CT-SS). In addition, the effects of patients' clinics, CT-SS, length of hospital stay, and intubation history on changes in the muscle area were investigated.

Results

When the PMA and PMI values were compared, there was a statistically significant decrease in the values in the control CT group compared to the first diagnosis CT group. The difference was found higher in intubated patients. CT-SS was associated with a decrease in PMI.

Conclusion

COVID-19 is one of the causes of acute sarcopenia. Pectoralis muscle is part of the skeletal muscle, and there may be a decrease in the muscle area in the early period of the disease.

Resumen
Objetivos

Sabemos que la COVID-19 afecta a múltiples órganos. Sin embargo, sus primeros efectos en el tejido muscular todavía no se han esclarecido. Este estudio tiene por objetivo investigar las alteraciones iniciales que se observan en el músculo pectoral de pacientes con COVID-19.

Materiales y métodos

Las áreas del músculo pectoral (AMP) y el índice del músculo pectoral (IMP) de 139 pacientes diagnosticados de COVID-19 se midieron a partir de TC (tomografías computarizadas) torácicas obtenidas en el momento de establecer el primer diagnóstico y en los 6 meses posteriores al mismo. El efecto de la infección en el área muscular se investigó mediante la evaluación de alteraciones entre las dos mediciones. La afectación pulmonar de la infección en la primera TC se puntuó según la puntuación de gravedad de la TC (CT severity score, CT-SS). También se investigaron los efectos de la clínica del paciente, la CT-SS, la duración del ingreso y los antecedentes de intubación en las alteraciones del área muscular.

Resultados

Al comparar los valores del AMP y el IMP, se observó una disminución estadísticamente significativa de los valores en el grupo con una TC de control en comparación con el grupo con una TC de primer diagnóstico. Se observó una mayor diferencia en los pacientes intubados. La CT-SS se asoció a una disminución del IMP.

Conclusión

La COVID-19 es una de las causas de sarcopenia aguda. El músculo pectoral forma parte del músculo esquelético, y puede producirse una disminución del área muscular en los periodos iniciales de la enfermedad.
