看看医生写为我妈的胸透结果

Tt was reported that you have some plaque formation in your aorta (the large blood vessel coming from the heart, taking blood to the lower half of your body.) Many people have this in their arteries, but it represents an increased risk of stroke and heart disease. The aspirin 81 mg daily is a good idea, and I would ask that you consider resuming the lipitor.

严重吗？ 要遵医嘱吗？
