"Flu and COVID Increase Risk of Myocarditis"

Respiratory and viral illnesses, including the flu and COVID-19, can lead to myocarditis, an inflammatory disease of the heart muscle. Symptoms may go unnoticed or be attributed to the initial illness, but warning signs include weakness, heart palpitations, and chest pains. Diagnosis involves EKG, blood tests, and heart imaging, with treatment focusing on symptom management and rest. Severe cases may require specific medication and mechanical heart support. Vaccination against the flu and COVID-19 is recommended, and caution is advised for persistent chest pain, particularly in cases of viral illness.
