If it were me, I would seek an echo-cardiogram or another type of test to determine CA deposition/plaque in the heart's own blood supply, but also in the carotid artery (Doppler ultrasound can help in this particular instance). But you really ought to put these questions to an expert, even a second or a third opinion if it will help you to 'triangulate' your way ahead. I'm no expert, but your LDL ratio doesn't look very promising, and when added to your CA score, PLUS....your genetic history...I would think you're going to need at least another helper advising you, maybe a cardiologist.....??

All that verbiage posted, I would have to say yes!
