Abstract
Objective To investigate the effect of ambulatory electrocardiogram combined with myocardial injury markers in the as-sessment of myocardial injury in children with pneumonia.Methods A total of 80 children with community-acquired viral pneumonia admit-ted to our hospital from 2022 to 2024 were retrospectively analyzed.All patients underwent 24 hour ambulatory ECG and myocardial marker detection,and were divided into a non-myocardial injury group(control group,n=45)and a myocardial injury group(n=35).Evaluation indicators included myocardial injury markers[creatine kinase isoenzyme MB mass(CK-MB mass),myoglobin(MYO),and cardiac tropo-nin(cTnT)],as well as microvolt-level T-wave alternans(MTWA)levels and the number of fragmented QRS complexes(fQRS).The pre-dictive value of combined detection in myocardial injury in children with community-acquired viral pneumonia was assessed using ROC curve analysis.Results Compared with the non-myocardial injury group,the number of fQRS cases and MTWA level were significantly increased in the myocardial injury group(P＜0.05);the CK-MB mass,MYO,and cTnT levels were significantly increased in the myocardial injury group(P＜0.05);the AUC of the combined diagnosis was 0.921(95％CI:0.763～0.966),with a sensitivity of 84.95％and a specificity of 88.32％,which was better than the single diagnostic indicator.Conclusion 24-hour ambulatory electrocardiogram combined with myocardial injury markers has high application value in the evaluation of myocardial injury in children with pneumonia.关键词
