Amyloid cardiomyopathy


Amyloid cardiomyopathy is a condition resulting in the death of part of the myocardium. It is associated with the systemic production and release of many amyloidogenic proteins, especially immunoglobulin light chain or transthyretin. It can be characterized by the extracellular deposition of amyloids, foldable proteins that stick together to build fibrils in the heart. The amyloid can be seen under polarized light in congo red stained biopsy.
