Which lipid parameter ratio is associated with higher ASCVD risk?

Atherogenic burden relative to protective HDL is what this ratio captures. Total cholesterol sums all cholesterol carried by lipoproteins, including LDL and other atherogenic particles, while HDL-C represents the protective, cholesterol-collecting fraction. When total cholesterol is high and HDL-C is relatively low, the ratio rises, signaling more cholesterol carried by potentially harmful particles and less protection. This higher TC to HDL-C ratio has long been linked with greater ASCVD risk in population studies and is simple to calculate from a standard lipid panel, making it a practical and well-supported risk marker. Other ratios reflect related ideas but are not as consistently predictive across diverse populations. For example, triglyceride to HDL-C highlights metabolic issues like insulin resistance and small dense LDL formation, but it’s more about a particular lipid pattern than overall atherogenic burden. LDL-C to HDL-C emphasizes the balance between a major atherogenic lipoprotein and HDL, but TC/HDL-C is a broader, widely used measure of overall cholesterol balance with regard to risk. Non-HDL-C to HDL-C also relates to atherogenic particle load but is less commonly used as a standalone global risk marker.
