I Had A Scan Without Contrast For A Lung Check,

I had a Scan without contrast for a lung check, everything was good, except the report from Radiologist stated on findings: "There is a borderline mild aneurysmal dilatation of the ascending thoracic aorta measuring 4.0 cm maximum transverse diameter." I am nervous. I am a male, 47 almost 48 5'10" 240 pounds with moderate high blood pressure. Is there any possible information or new studies to help this condition? Thank you.
