Amyloidosis is a group of diseases that result from the abnormal deposition of a particular protein, called amyloid, in your heart. These proteins are produced in excess by the body and slowly deposited where they replace normal heart tissue and causes your heart to not function properly. The cause of amyloidosis is unknown but is thought to result from many factors. It is not, however, a form of cancer.

  • Echocardiogram
  • Chest x-ray
  • CT scan
  • Coronary angiography
  • Nuclear heart scan, such as MUGA scan
