Atherosclerotic Plaque Seen in Aortic Arch

My husband is 63, trim, in great physical health, able to exercise to his fullest. He had a triple CABG 2 years ago and had a stress test last month that his cardiologist said he passed with flying colors. His cholesterol has gone from 271 to 145. He had a very very small artery that was 40% blocked that was not bypassed. He recently had a chest xray for asthma and the results were atherosclerotic plaque is seen in the aortic arch. Postoperative changes of CABG are noted. The cardiomediastinal silhouette and boens are unremarkable. He feels great. Is there any need for concern?
Many thanks!

The report is very good.  The small artery, if a problem, would most likely cause symptoms such as chest pain.  If the atherosclerotic plaque seen in the aortic arch is a problem, it would likely increase blood pressure and possibly enlarge the left ventricle.  

Thanks for sharing.
