I have a score of 205 and am on statins.

The score doesn't necessarily mean a blockage. Plaque builds up on the walls of the arteries. It's like a drain pipe that has buildup so that there's a narrower space for the water to flow. A stent widens the space (I don't have one, by the way.) If the artery gets completely blocked, then bypass surgery is a possibility.

Also, important to note that you don't need perfectly clear arteries to live. I have a 40% narrowing in an artery, I go jogging 3x week and I go to the gym. I feel fine. The statin, along with a better diet, helps keep things from getting worse. And if you get your LDL low enough, the plaque can regress somewhat. Nothing can remove it, though.
