Long-term cardiac surveillance and outcomes of COVID-19 patients

Area of Science:

• Cardiology
• Infectious Diseases
• Public Health

Background:

• Acute cardiac manifestations of COVID-19 are known, but chronic cardiac sequelae are less understood.
• Conflicting data exists regarding the prevalence of new or worsening cardiovascular disease, myocarditis, or arrhythmias post-COVID-19 recovery.
• Emerging data suggests an increased incidence of myocarditis and arrhythmias in COVID-19 survivors compared to controls.

Purpose of the Study:

• To clarify the chronic cardiac sequelae following COVID-19 infection.
• To assess the incidence of myocarditis and arrhythmias in recovered COVID-19 patients.
• To provide guidance for the return to exercise and competition for athletes post-COVID-19.

Main Methods:

• Review of existing studies on cardiovascular outcomes after COVID-19.
• Analysis of data from athletes undergoing screening protocols before returning to activity.
• Synthesis of consensus statements regarding cardiovascular assessment in post-COVID-19 athletes.

Main Results:

• The incidence of myocarditis post-COVID-19 infection is low but significantly higher than vaccine-associated myocarditis.
• Studies on athletes show possible, probable, or definite myocarditis or cardiac injury in 0.4-3.0% of cases.
• Consensus suggests athletes with full recovery and no cardiopulmonary symptoms can return to exercise without cardiac testing.

Conclusions:

• Patients recovering from COVID-19 have an increased risk of cardiovascular disease, myocarditis, or arrhythmias during convalescence.
• The majority of patients, including athletes, can return to normal activities after COVID-19 recovery if asymptomatic.
• Continued monitoring and research are needed to fully understand long-term cardiac implications of COVID-19.
