Is ct cardiac calcium scan accurate in diagnosing mild ectatic ascending aorta? have fam. history of heart disease (father died at 46 with chf) and slight heart murmur. should i have other tests done

Ectasia: The ectasia is likely. You need good BP control, lipid control, not smoking, cholesterol control in any case and that's all you can do about the ectasia anyway.

No: You need an aortic ultrasound to determine if it is too large. A calcium score of the abdominal aorta is useless. A vest x-ray with abdominal view can tell you if you have a mildly ecstatic aorta or not but that is not harmful. If your doc is concerned the best test would be a stress test of your heart. Talk to your doc.
