Electrocardiographic findings over time and their prognostic value in patients with COVID-19

To explore the application of serum cardiac troponin T (cTnT), brain natriuretic peptide (BNP) levels, and electrocardiogram changes in the treatment and prognosis evaluation of severe pneumonia in children. Methods: 120 children with severe pneumonia (severe group) admitted to our hospital from June 2020 to December 2022 were selected as the study subjects with prospective study. They were divided into survival group (n=78) and death group (n=42) based on their survival status; 120 children with mild pneumonia were selected as the control group. Compare the levels of serum cTnT and BNP, as well as the changes in electrocardiogram, to analyze their predictive value for the prognosis of pediatric patients and the influencing factors of prognosis. Results: The proportion of children with cTnT, BNP, and abnormal electrocardiogram after treatment was lower than before treatment (P<0.05). The proportion of children with cTnT, BNP, and abnormal electrocardiogram in the severe group was higher than that in the mild group (P<0.05). The proportion of children with serum cTnT, BNP levels, and abnormal electrocardiogram in the death group after treatment was higher than that in the survival group (P<0.05). Bundle branch block, low or inverted T waves, cTnT, and BNP are prognostic factors for children with severe pneumonia (P<0.05). The combined prediction of serum cTnT and BNP for the prognosis of severe pneumonia in children is better than that of single prediction (Z combined detection -cTnT=2.474, Z combined detection -BNP=2.494, P=0.013, 0.013). Conclusion:The proportion of abnormal cTnT, BNP, and electrocardiogram is increased in patients with severe pneumonia, and those with high expression and abnormalities have poor prognosis. cTnT and BNP have high predictive value for the prognosis of children with severe pneumonia.
