Dear friend, welcome to HCM.
your report shows changes due to old heart bypass
mild changes of arthritis
in thoracic(chest) vertebrae, which is acceptable for age.
but the aorta
(the main supplying blood vessel of the body) shows calcium deposits, which occurs with age, but is still capable of causing arterial blocks/ flown into smaller arteries and blocking them , like your heart vessels did.
you should continue the medicines advised by your heart surgeon/ cardiologist.
you need not see a doc soon , as not much can be done to the aortic calcification right now. but be aware of pain, discoloration, coldness, numbness
, abdominal pain
in future and report immediately , if these occur.
if you get money and see your doc , pl. ask him about aortic calcification. and ber guided.
take care and keep posted.
