There are different lipid levels consisting of LDL,HDL, Cholesterol etc which affects atherosclerosis of coronaries. What is the impact of remanent cholesterol for causing IHD whether is it more toxic over LDL & cholesterol or otherwise.
The key lipid risk factor is the balance between LDL-c and HDL-c, but especially the ratio between these two--a ratio such as the Cholesterol Retention Fraction (CRF, defined as [LDL-HDL]/LDL). (The LDL-c:HDL-c ratio is slightly less sensitive and suffers from poor reproducibility.) There is no doubt that HDL-c--or more specifically, apo A-1--is protective against atherothrombotic disease, so the amount of LDL-c accumulating within the artery wall depends upon its associated HDL-c level. Non-HDL-c is simply LDL-c with TG-c, but whn TG-c is high HDL-c is virtually always low. IDL-c is not a player in most people. CT should be relegated to the dylsipidemia historical files
