ABSTRACT
OBJECTIVE:
To investigate the specific role of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in inducing elevation of marker of myocardial injury in infants with acute coronavirus disease 2019 (COVID-19). STUDYDESIGN:
A prospective, multicentric 3-arm comparative study (March 2020 through March 2022) enrolling 152 infants hospitalized for COVID-19, 79 children with acute infections other than SARS-CoV-2, and 71 healthy controls. Determination of high-sensitivity cardiac troponin (hs-cTn) levels was the primary outcome.RESULTS:
The proportion of children with hs-cTn values above the upper limit of normal (44 [28.9%]), as well as with a 3-fold increased value (20 [13.2%]) were significantly higher in the COVID-19 group than those in both control groups. The risk of presenting a 3-fold increased hs-cTn value was higher in children with SARS-CoV-2 infection compared with either healthy children (OR, 5.23; 95% CI, 1.19-23.02) or those with other infections (OR, 11.89; 95% CI, 1.56-89.79). In children with COVID-19, hs-cTn elevation was associated with neither clinical nor biochemical characteristics, nor perinatal risk factors, but with an age of <3 months (P < .001). After adjustment for age, sex, and underlying clinical conditions, elevated hs-cTn was independently associated with COVID-19 in a multivariable regression model. All children showed a progressive reduction of hs-cTn until normalization over time, without clinical, ECG, or echocardiographic manifestations up to 1 year of follow-up.CONCLUSIONS:
Infants with acute SARS-CoV-2 infection may show a subclinical and transient alteration of myocardial injury markers, especially in the first months of life. hs-cTn levels normalized during follow-up and were not associated with cardiac functional impairment; nevertheless, long-term consequences are unknown and should be followed carefully.Key words
