Which lipid parameter is the primary target to reduce ASCVD risk in lipid management?

Lowering LDL cholesterol is the main target for reducing ASCVD risk because LDL particles are the primary drivers of atherogenesis. Lower LDL-C has the strongest and most consistent evidence across many randomized trials that it translates into fewer heart attacks and strokes. Treatments like statins, and add-ons such as ezetimibe or PCSK9 inhibitors, reduce events largely by decreasing LDL-C levels. Other lipids don’t offer the same, broad-cut evidence. Raising HDL-C, despite observational associations with reduced risk, has not reliably lowered ASCVD events when targeted therapeutically. Triglycerides are linked to risk, especially in insulin resistance and high TG states, and lowering them helps in specific high-risk groups, but it hasn’t shown the same universal benefit as lowering LDL-C. Lp(a) is an independent risk factor, but therapies to specifically lower it are not yet as established in routine practice as LDL-C–lowering strategies. So, the primary focus to reduce ASCVD risk is lowering LDL cholesterol.
