Hi, Thanks for using healthcaremagic. I understand you must have undergone a coronary CT study which would have given you the calcium scores and measurement of ascending aorta. Calcium score upto 400 in total is normal and is not associated with significant stenosis. However, it is an arbitrary method and just shows a general trend rather than a specific person s clinical condition. People with less calcium scores can also have blockages while people with more calcium scores can live disease free. So it is not a very good marker for disease rather only a trend for determining disease status in community. Aneurysmal dilatation of aorta is something you need to be worried about, especially in the ascending aorta segment as it is the most dangerous segment. The normal diameter is upto 4 cms so it is slightly dilated and regular follow up should be done. If there is an increase in size or if you are having any sudden chest pain you should immediately get a repeat study done to assess the aorta. So your greatest concern should be the aneurysmal dilatation of aorta and you should be careful about it. Hope it sorts your problem and wishing you a speedy recovery.
