COVID-19 myocarditis and prospective heart failure burden

Area of Science:

• Cardiology
• Infectious Diseases
• Cardiovascular Medicine

Background:

• COVID-19 causes significant global morbidity and mortality.
• Cardiac involvement is common, with myocardial injury observed in many hospitalized patients.
• The long-term cardiovascular outcomes for COVID-19 survivors remain unclear.

Purpose of the Study:

• To investigate the extent and mechanisms of myocardial injury in COVID-19.
• To understand the short and long-term cardiovascular sequelae in COVID-19 survivors.
• To assess the risk of persistent myocardial injury and its consequences.

Main Methods:

• Review of observational studies on viral myocarditis and COVID-19.
• Analysis of reported cardiovascular complications in COVID-19 survivors.
• Discussion of cardiac magnetic resonance (CMR) findings in myocarditis-like changes.

Main Results:

• Myocardial injury in COVID-19 patients is linked to a worse prognosis.
• Late-onset cardiovascular complications, including myocarditis-like changes, have been reported in survivors.
• Viral myocarditis studies suggest incomplete recovery with potential left ventricular dysfunction.

Conclusions:

• COVID-19 poses a significant threat to cardiac health.
• Persistent myocardial inflammation and injury may occur in COVID-19 survivors.
• Early detection of residual myocardial changes is vital for identifying at-risk patients.
