Cardiac amyloidosis is a rare but increasingly recognized cause of heart failure, often underdiagnosed until later stages of the disease. This report describes a case of transthyretin amyloidosis (ATTR) in a 68-year-old male patient with a significant medical history of rheumatoid arthritis (RA), a combination seldom documented in the literature. The patient presented with progressive symptoms of heart failure, and diagnostic testing confirmed ATTR cardiac amyloidosis through pyrophosphate (PYP) scanning.

Symmetric inflammatory polyarthritis is the most prominent manifestation of rheumatoid arthritis (RA). However, RA can practically affect any organ system, whether hematologic, neurological, cardiac, lung, skin, eyes, or kidneys. Systemic involvement in RA can be severe when there is interstitial lung disease, scleritis, amyloidosis, pure red cell aplasia, or myelodysplasia.

Alkaptonuria (AKU) is a rare autosomal recessive metabolic disorder caused by mutations in the homogentisate 1,2-dioxygenase (HGD) gene, leading to the accumulation of homogentisic acid (HGA), causing severe inflammatory conditions. Recently, the presence of serum amyloid A (SAA) has been reported in AKU tissues, classifying AKU as novel secondary amyloidosis; AA amyloidosis is characterized by the extracellular tissue deposition of fibrils composed of fragments of SAA. AA amyloidosis may complicate several chronic inflammatory conditions, like rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel disease, chronic infections, neoplasms, etc.
