What Does "mildly Ectatic Aorta" In A Chest X-ray Indicate?

I am 59 years old and had a chest x-ray done. the lungs were cleared but it stated that I had a heart normal in size with a mildly ectatic aorta. what does this mean?
it also said that degenerative changes are present in the spine. What does this mean and what can be done to correct or take care of these results?
Thank You........
