Cardiac amyloidosis: A case report and review of literature

Cardiac amyloidosis, a disease caused by the precipitation of amyloid proteins in the myocardial extracellular matrix has been historically difficult to diagnose due to lack of specific clinical manifestations and necessity of biopsy to demonstrate amyloid deposition. However, advances in cardiovascular imaging techniques have facilitated earlier recognition of this disease. In addition, while once thought of as incurable, treatment strategies are emerging for cardiac amyloidosis, making early diagnosis essential.

We outline the case of a 73 years old African American female who was admitted with sudden onset shortness of breath and found to be in cardiogenic shock. Cardiac amyloidosis was suspected due to discordance between electrocardiogram and echocardiogram findings and this was subsequently confirmed with the aid of scintigraphy and an endomyocardial biopsy.

Our objective is to highlight the diagnostic evaluation and clinical implications of cardiac amyloidosis.
