I feel inadequate in answering your questions, but since no one has commented and you sound anxious, I will share my experience. I recently had a carotid US. My numbers are nearly identical to yours. I am not concerned nor is my cardiologist. The US says you have a mild, slight amount of plaque and no significant stenosis in either carotid bifurcation. You have adequate cerebral blood supply and oxygenation.
How and why do you have a slight amount of plaque in your carotid artery?
You didn't mention your age, if you've had a CAC scan, or if you've had a comprehensive lipid panel including APOB and Ap(a).
If no one else replies, ask chat GPT to interpret your results like a functional medical doctor. I did this for one of my blood tests and I did a good job explaining so I could understand.
