Additional Info
Myocarditis is an inflammatory disease of cardiac muscle that is caused by a variety of infectious and noninfectious conditions. We differentiate between the following in this database:
- Myocarditis/carditis, acute infective
- Myocarditis, chronic
- Myocarditis, acute noninfective
- Myocarditis, acute NOS
Acute myocarditis has been defined as a condition with symptoms (most commonly of heart failure) developing over three months or less, while chronic myocarditis has been defined as developing over greater than three months.
The relationship between myocarditis and cardiomyopathies is complex. Myocarditis can (but may not) result in a cardiomyopathy, or it may resolve completely. In many people with cardiomyopathy, there may have been a myocarditis in the past, but the inflammatory component is gone by the time the cardiomyopathy is diagnosed.
Diagnostic criteria: New 12-lead ECG and/or Holter and/or stress testing abnormalities
- Elevated troponin T or troponin I.
- Functional and structural abnormalities on cardiac imaging (echocardiogram, angiogram, or CMR)
- Tissue characterization by CMR (cardiovascular magnetic resonance) or EMB (endomyocardial biopsy)
