Myocarditis

Myocarditis is inflammation of the heart muscle that can present with chest pain, heart failure, arrhythmias, or cardiogenic shock.

In this episode, Chris and Mars review:

• The classic post-viral presentation
• Why myocarditis can mimic myocardial infarction
• Troponin, E C G, echocardiography, and cardiac M R I findings
• Myocarditis versus pericarditis
• When endomyocardial biopsy is indicated
• Fulminant and giant-cell myocarditis
• Heart-failure and arrhythmia management
• Exercise restriction and return to activity
• Dilated cardiomyopathy and sudden cardiac death as important complications

Episode pearl: Elevated troponin means myocardial injury—not necessarily myocardial infarction. In the right clinical setting, think myocarditis.
