I have mild calcific thoracic aorta, is there something to do with heart disease.?

Yes. Most people are speaking about atherosclerosis, when talking about heart disease. Calcification in the thoracic aorta is not necessarily atherosclerosis; however, atherosclerosis is often found upon further investigation. Other risk factors that should be addressed include smoking cessation and blood pressure control. Your primary physician can manage these and discuss further testing.
