- QUESTION: Something is affecting my father's heart which is causing it to
- fail. The doctors call it a "stiff heart" and that a "protein" is collecting
- in the muscles of the heart, preventing them from contracting properly. We
- were told it is rare, and that there is no treatment. Have you ever heard of
- this condition, and do you know of any treatment that can be used to help my
- father? Please help us in any way you can.

- ANSWER: Though a "stiff heart" may develop from many causes, your letter (and
- some of the information you provided for which I do not have room here)
- indicates to me that your father is suffering from "myocardial amyloidosis".
- Amyloid is an insoluble fibrous protein which can collect in many of the
- body's organs, the heart, liver, kidneys, spleen and others. Three forms of
- the disease are recognized: primary amyloidosis where no apparent reason
- exists for the deposition of the amyloid; secondary amyloidosis, which results
- as a result of other diseases which include tuberculosis, multiple myeloma,
- rheumatoid arthritis and others; and a third type called hereditary
- amyloidosis, in which a genetic link can be identified. The amyloid collects
- in the heart muscles, changing their properties and rendering them less
- elastic. In addition the walls of the heart's chambers become thicker, and
- require more force to contract. Over time, the heart can't propel the blood
- forward into the arteries in the normal quantities, and the blood "backs up"
- into the lung tissue. And that results in the condition known as "heart
- failure".
- No one knows the exact mechanism by which the amyloid is deposited in the
- heart and other organs. If this is the result of other diseases, the
- treatment is directed at the underlying disease, which, when effective, can
- slow down or stop the progress of the amyloidosis. When no cause is apparent,
- doctors treat the heart failure as they would treat failure from any cause.
- Currently research is in progress that seeks to evaluate the use of
- prednisone, melaphalan, and colchicine in the treatment of primary
- amyloidosis.
