Template:ICD10 Guideline Myocarditis
Template to make sure extra information is consistent for the various Myocarditis diagnoses.
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
It can be an acute, subacute, or chronic disorder, and may present with focal or diffuse involvement of the myocardium. Myocarditis can be produced by a variety of infectious and noninfectious causes. In addition, many inherited cardiomyopathies (eg, Fabry disease and arrhythmogenic right ventricular [RV] cardiomyopathy) may present with features of acute or chronic myocarditis.
Acute myocarditis has been defined as a condition with symptoms of HF developing over three months or less, while chronic myocarditis has been defined as developing over greater than three months.
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)
