Insights
Acute COVID-19 can cause cardiac abnormalities in children. Electrocardiogram and troponin tests help identify children at risk for heart injury during acute coronavirus disease 2019.
Area of Science:
- Pediatric Cardiology
- Infectious Diseases
- Cardiovascular Medicine
Background:
- Coronavirus disease 2019 (COVID-19) is associated with cardiac abnormalities in adults.
- Cardiac effects in children with acute COVID-19 are less understood compared to multisystem inflammatory syndrome.
Purpose of the Study:
- To assess the cardiac effects of acute COVID-19 in hospitalized children (<21 years).
- To identify potential biomarkers for cardiac injury in pediatric COVID-19 patients.
Main Methods:
- Retrospective observational study across three New York City healthcare systems.
- Analysis of electrocardiograms, echocardiograms, troponin, and B-type natriuretic peptide levels.
- Inclusion of 317 hospitalized pediatric patients.
Main Results:
- 41% of tested children (131/317) showed cardiac abnormalities.
- Electrocardiogram abnormalities (39%) and elevated troponin (18%) were common findings.
- Ventricular dysfunction was observed in 19% of echocardiogram-tested patients, resolving by follow-up.
Conclusions:
- Electrocardiogram and troponin levels are valuable tools for identifying children at risk of cardiac injury from acute COVID-19.
- Prompt identification and monitoring can aid in managing cardiac complications in pediatric COVID-19.
Abstract:
Introduction Coronavirus disease 2019 (COVID-19) is known to cause cardiac abnormalities in adults. Cardiac abnormalities are well-described in multisystem inflammatory syndrome in children, but effects in children with acute COVID-19 are less understood. In this multicenter study, we assessed the cardiac effects of acute COVID-19 among hospitalized children (<21 years) admitted to three large healthcare systems in New York City. Methods We performed a retrospective observational study. We examined electrocardiograms, echocardiograms, troponin, or B-type natriuretic peptides. Results Of 317 admitted patients, 131 (41%) underwent cardiac testing with 56 (43%) demonstrating cardiac abnormalities. Electrocardiogram abnormalities were the most common (46/117 patients (39%)), including repolarization abnormalities and QT prolongation. Elevated troponin occurred in 14/77 (18%) patients and B-type natriuretic peptide in 8/39 (21%) patients. Ventricular dysfunction was identified in 5/27 (19%) patients with an echocardiogram, all of whom had elevated troponin. Ventricular dysfunction resolved by first outpatient follow-up. Conclusion Electrocardiogram and troponin can assist clinicians in identifying children at risk for cardiac injury in acute COVID-19.
