A Rare Culprit Or An Elusive Culprit In Disguise? Unraveling Wild-Type Attr Cardiac Amyloidosis In Heart Failure With Reduced Ejection Fraction, Jose J. Loayza Pintado, Taiwo Ajani, Daniela Hernandez, Everardo Cobos

School of Medicine Publications

Cardiac amyloidosis (CA) is a rare disorder caused by the deposition of abnormal proteins called amyloid in the myocardium, leading to dysfunction. The 2 most common forms of amyloidosis are AL (light chain) and ATTR (transthyretin). Diagnosing amyloidosis is challenging, especially in its early stages, due to its nonspecific symptoms and overlap with other conditions. Recent studies suggest that the incidence of wild-type transthyretin amyloidosis is rising, likely due to improved diagnostic techniques and an aging population. We present the case of a 72-year-old male with lower extremity edema, progressive shortness of breath, and worsening renal function. He had a …
