Diagnosis of Myocarditis
The diagnosis of myocarditis as per the European Society of Cardiology
Working Group on Myocardial and Pericardial Diseases, requires
fulfillment of ≥1 clinical presentation and ≥1 diagnostic criteria.
These criteria have to be fulfilled in the absence of coronary artery
disease as detected by coronary angiography, and absence of pre-existing
cardiovascular disorder that can otherwise explain the presentation(9). All studies included in the
meta-analysis made a clinical diagnosis of myocarditis that fulfilled
international criteria as per European Society of Working Group on
Myocardial and Pericardial diseases. Whilst the majority of studies used
CMR diagnostic criteria (non-ischemic late gadolinium enhancement and/or
Lake Louise Criteria) (10) ,
others used echocardiography and/or endo-myocardial biopsy for
diagnosis.
