Delayed Diagnosis of Cardiac Amyloidosis Masked by Chronic Coronary Artery Disease and Ischemic Cardiomyopathy: A Case Report of an Overlooked and Underdiagnosed Etiology.

Cardiac amyloidosis (CA) is an infiltrative disease of the heart characterized by the deposition of insoluble protein aggregates in the myocardium. There are two subtypes of CA, and they are named after the misfolded protein. Transthyretin cardiac amyloidosis (ATTR-CA) is caused by the accumulation of the tetrameric transthyretin protein produced in the liver, and light-chain cardiac amyloidosis (AL-CA) occurs due to circulating abnormal light-chain deposition. Disease manifestation can be very non-specific, and there can be overlap with other cardiac processes. This often leads to a delay in diagnosis and a poor prognosis. Here, we present a case of delayed diagnosis of CA spanning over several years that required a multidisciplinary approach but ultimately resulted in fatality six years after the initial diagnosis.
