This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
That means you have aortic aneurysm involving ascending aorta measuring 4.5 cm ( normal about 2.8 cm for male).
This may not produce any symptoms.
A CT scan or MRI should be repeated after 6 months to assess its stability.
If it becomes larger than 5.5 cm then surgical repair is indicated to prevent complications like aortic rupture.
A beta blocker like metoprolol should be started to prevent aortic dilatation.
A statin like atorvastatin should be started to prevent plaques.
Also aortic valve should be assessed for any abnormalities.
A cardiologist should be consulted with.
It was my pleasure to help you today.
