Insights
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes myocardial injury (MI) in COVID-19 patients, increasing mortality risk. Understanding the mechanisms of SARS-CoV-2-induced MI is crucial for developing targeted therapies.
Area of Science:
- Cardiology
- Infectious Diseases
- Pathophysiology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) impacts multiple organs, including the cardiovascular system.
- Myocardial injury (MI) is a significant complication of coronavirus infectious disease 2019 (COVID-19), linked to poor outcomes and increased mortality.
- Manifestations of COVID-19-related MI include myocarditis, stress cardiomyopathy, acute coronary syndrome, and pulmonary embolism.
Purpose of the Study:
- To review the current understanding of potential mechanisms underlying COVID-19-induced MI.
- To discuss advancements in therapeutic strategies for managing MI in COVID-19 patients.
Main Methods:
- Literature review of studies investigating SARS-CoV-2 and cardiovascular complications.
- Analysis of proposed pathophysiological pathways for myocardial injury.
- Synthesis of current therapeutic approaches and future directions.
Main Results:
- Multiple mechanisms contribute to COVID-19-related MI, including direct viral invasion and indirect inflammatory/thrombotic pathways.
- The interaction with angiotensin I converting enzyme 2 (ACE2) and endothelial dysfunction are implicated.
- Understanding these mechanisms is key to developing effective treatments.
Conclusions:
- COVID-19 poses a significant threat to cardiovascular health, with MI being a critical concern.
- Further research into the complex mechanisms of SARS-CoV-2-induced MI is warranted.
- Targeted therapeutic strategies are needed to mitigate cardiovascular complications and improve patient outcomes.
Abstract:
Severe acute respiratory syndrome coronavirus 2 infection affects not only the lungs, but also the cardiovascular system, having a major impact on patients' outcomes. Myocardial injury (MI) occurs in the context of coronavirus infectious disease 2019 (COVID-19) and is associated with a higher risk of severe clinical outcome and mortality. COVID-19-related MI can have various clinical manifestations, of which the main ones are myocarditis, stress cardiomyopathy, acute coronary syndrome, and pulmonary embolism. The exact mechanisms of how MI occurs in these patients are not yet fully known. Direct injury, through direct viral myocardial invasion, and indirect injury, through interaction with angiotensin I converting enzyme 2, increased inflammation, and thrombocyte and endothelial dysfunction, could be involved in acute MI in patients with COVID-19. A better understanding of these multiple potential mechanisms may help to develop new targeted therapeutic strategies. The purpose of this review is to provide the current understanding of the potential mechanisms involved in MI induced by COVID-19 and to discuss the current progress in the therapeutic strategies.
