RATIONALE AND OBJECTIVES: The aim of our study was to evaluate whether there is any correlation between a histogram analysis of the pectoralis muscle derived from chest computed tomography (CT) and the mortality rate for COVID-19 pneumonia in the adult population. METHOD: Chest CT derived measurements were evaluated retrospectively for 217 patients with a diagnosis of COVID-19 pneumonia. Using a CT histogram analysis, we measured pectoralis muscle volume (PV) and pectoralis muscle density (PD). Patients were divided into groups first according to gender and then subgroups, which are age and outcome. RESULTS: The COVID-19 diagnoses were confirmed by RT-PCR testing, chest CT and clinical findings in 217 patients (108 men, 109 women), aged 21-92 years (mean 61 years). PD measurements were lower in the exitus group (p = 0.001) and in patients aged >/=65 than in those aged <65 years (p < 0.05). There was a significant difference between PD measurements of outpatient and inpatient under 65 years age (p < 0.05). Additionally, there was a statistically significant difference between fatty volume measurements according to the exitus status of cases (p < 0.05). CONCLUSION: CT-derived measurements of the pectoralis muscle can be useful in predicting disease severity and mortality rate of COVID-19 pneumonia in adult patients.
