Myocarditis Leading to Severe Dilated Cardiomyopathy in a Patient with Dengue Fever

Abstract EN

Background.

Majority of dengue fever cases follow a benign self-limiting course but recently rare presentations and complications are increasingly seen due to rising burden of disease.

Cardiac involvement in dengue fever with fatal outcome is a very rare complication.

We report a case of 44-year-old patient who presented with symptoms of severe acute congestive heart secondary to myocarditis induced cardiomyopathy caused by dengue virus infection.

Case Presentation.

A 44-year-old man presented to ER with the complaints of high fever, fatigue, and shortness of breath.

Patient was lethargic and blood pressure was low when he was brought to the ER.

CXR showed cardiomegaly with pulmonary congestion and echocardiography revealed dilated left ventricle and ejection fraction of 10%.

Patient condition worsened and he got admitted to the ICU because of acute hypoxic respiratory failure.

Despite aggressive measures, patient died on day 5.

Conclusion.

Dilated cardiomyopathy is a rare complication of dengue myocarditis.

Early recognition of acute DCM caused by dengue myocarditis is imperative in the management of dengue fever as early detection and management of cardiac failure can improve the survival of patient.
