What is Myocarditis?
Myocarditis is usually caused by a viral infection. A severe case can weaken the heart, which can lead to heart failure, abnormal heartbeat and sudden death.
3.1 million cases of myocarditis were diagnosed worldwide in 2017 (statistics posted in Lancet, November 2018)
The majority of cases of myocarditis have no symptoms and are not diagnosed.
