Abstract
Background
Recent reports in the literature have indicated that infection by coronavirus disease 2019 (COVID-19) causes cardiac complications, such as heart failure, arrhythmia, myocardial infarction, and even fulminant myocarditis. These complications have been identified as the cause of death in some patients infected with SARS-CoV-2.
Objectives
To analyze echocardiographic and electrocardiographic changes, treatments used, and clinical outcomes in patients with myocarditis and COVID-19.
Methods
The items described for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were followed. This review included articles in English, Portuguese, and Spanish that reported cardiac involvement, injury, or myocardial inflammation in patients who acquired COVID-19 (SARS-CoV-2).
Results
Five databases were consulted to find 1,726 articles. After applying the eligibility criteria, a total of 22 studies were considered qualified. ST-segment (section of the electrocardiogram corresponding the end of the S wave to the beginning of the T wave) elevation and tachyarrhythmia were the most common changes found in the electrocardiographic analysis of patients affected with COVID-19. Concerning echocardiography, there was a high frequency of decreased ejection fraction and occurrence of pericardial effusion.
Conclusion
This systematic review provides a potential tool for the analysis of cardiac changes and implications caused in patients affected by SARS-CoV-2 infection, with emphasis on the presence of tachyarrhythmia on electrocardiogram (ECG) and decreased ejection fraction on echocardiogram.
