[|Human|] Is there anything to worry about with a calcium score of 71-non-obstructive disease of anterior descending coronary artery 25-50% stenosis and right coronary artery 0-25% stenosis with ejection fraction that appears reduced?  Was denied insurance coverage because of this but my physician told me all was normal.
[|AI|]  Hi, Thank you for query As per your question CT coronary angiogram has very low sensitivity of about 60%Only stenosis more than 755 are normal. Developing plaques is a natural process, and it starts soon after age of 10 years, Every one has some amount of blockage, however clinically blockages which are more than 75% are significant only. Pleasespecify your ejection fraction value clearly. Yes if ejection fraction is critically or moderately low then detailed and specific test like coronary angiogram has to be done
