Viral infection of the heart (viral myocarditis)

Case study: A 49-year old lady suffered a viral infection for about 3 weeks before she succumbed to a fatal acute viral myocarditis. Discuss her case in the light of technological advances we have today to diagnose her cause of death.

Myocarditis is inflammation of the heart muscle. Myocarditis may occur after a viral, fungal, or bacterial infection, such as diphtheria, rheumatic fever, or tuberculosis.


Myocarditis is an important and often unrecognized cause of dilated cardiomyopathy (DCM). It is defined as inflammation of the heart muscle that may be identified by clinical or histopathologic criteria. 

Recent developments in the diagnosis and treatment of patients with suspected myocarditis include improved histologic criteria and use of cardiac magnetic resonance imaging (MRI). 

Treatment for myocarditis includes evaluation and treatment of the underlying cause of the inflammation. Treatment may require use of antibiotics, if a bacterial infection is the cause, and medications to relieve pain and inflammation. Lifestyle changes, including increased rest and a low-salt diet, may be part of the treatment.
