LDL-c doesn't start to be problematic above 190 mg/dl. The risk starts growing well below that amount, and it continues to rise more quickly.
Here's a rough estimate of coronary heart disease risk vs LDL-c levels, normalized to 100 mg/dL:

For optimal heart health, I'd aim for as low an LDL-c level as you can manage. The medical guidelines call for controlling to less than 100, but I think that is still too high.
