Insights
This study confirms lymphocytic viral myocarditis can occur in elderly patients with coronavirus disease (COVID-19). Autopsy findings revealed characteristic myocardial inflammation and potential co-occurrence with other cardiac inflammatory conditions.
Area of Science:
- Cardiology
- Pathology
- Infectious Diseases
Background:
- Myocarditis, inflammation of the heart muscle, is a potential complication of viral infections.
- Elderly patients with confirmed coronavirus infection present unique challenges for diagnosis and management.
Observation:
- The study examined four autopsy cases of elderly patients with confirmed coronavirus infection.
- Morphological and immunohistochemical analyses were conducted on heart specimens to characterize myocardial inflammation and cellular infiltrates.
Findings:
- Lymphocytic viral myocarditis was morphologically and immunohistochemically confirmed in COVID-19 patients.
- Key features included the presence of coronaritis (inflammation of coronary arteries) and potential concurrent endo- and pericarditis.
Implications:
- These findings highlight the importance of considering myocarditis in elderly COVID-19 patients, even in autopsy cases.
- Understanding the specific features of COVID-19-associated myocarditis can aid in diagnosis and management of cardiac complications.
Abstract:
The paper describes 4 autopsy cases of myocarditis in elderly patients with confirmed coronavirus infection. It gives the data of a morphological study of heart specimens and a detailed characterization of a myocardial infiltrate. An immunohistochemical study with cellular infiltrate typing was performed. The fact that lymphocytic viral myocarditis can develop in COVID-19 was morphologically and immunohistochemically confirmed. The features of myocarditis in COVID-19 are the development of the former in the presence of coronaritis and the possibility of its concurrence with lymphocytic endo- and pericarditis.
