COVID-19-Associated Myocarditis: An Evolving Concern in Cardiology and Beyond

Area of Science:

• Cardiology
• Infectious Diseases
• Immunology

Background:

• Direct and indirect adverse effects of SARS-CoV-2 infection on the cardiovascular system are critical, impacting disease course, clinical outcomes, and recovery.
• Myocarditis, an inflammation of the heart muscle, is a significant concern associated with SARS-CoV-2 infection.
• Rapidly evolving knowledge necessitates continuous updates for the scientific and medical community regarding COVID-19-associated cardiovascular complications.

Purpose of the Study:

• To provide an updated review on the incidence of Coronavirus disease 2019 (COVID-19)-associated myocarditis.
• To summarize recent data on the pathophysiology and diagnostic evaluation of COVID-19-associated myocarditis.
• To include an update on proposed mechanisms of myocarditis in COVID-19 vaccine recipients.

Main Methods:

• Literature review and synthesis of recent data.
• Analysis of incidence rates and risk factors for COVID-19-associated myocarditis.
• Review of diagnostic tools, including serum biomarkers and imaging modalities.
• Examination of proposed mechanisms for vaccine-induced myocarditis.

Main Results:

• Recent data indicate a relatively low overall incidence of SARS-CoV-2-associated myocarditis.
• Individuals infected with SARS-CoV-2 exhibit a substantially increased risk of developing myocarditis.
• Understanding pathophysiology and diagnostic evaluation remains crucial for managing COVID-19-associated myocarditis.

Conclusions:

• COVID-19-associated myocarditis, though not highly frequent, poses a significant risk to infected individuals.
• Continued research into diagnostic strategies and pathophysiological mechanisms is essential.
• Emerging data on vaccine-associated myocarditis warrant attention and further investigation.
