Which lipid parameter is most strongly associated with increased cardiovascular risk due to atherogenesis?

• A. HDL
• B. LDL
• C. Triglycerides
• D. VLDL

Answer: (B)

LDL cholesterol is the lipid parameter most strongly linked to atherogenesis because LDL particles infiltrate the arterial intima, where they become oxidized. Oxidized LDL triggers an inflammatory response, recruits macrophages, and leads to foam cell formation and fatty streaks that progressively develop into atherosclerotic plaques. The amount of cholesterol carried by LDL directly correlates with the extent of plaque burden and cardiovascular risk, making it the primary driver of atherogenesis.

HDL, in contrast, helps remove cholesterol from arteries and is generally associated with lower risk, but it does not contribute to plaque formation in the same direct, causal way. Triglycerides and VLDL are linked to cardiovascular risk as part of a broader metabolic syndrome picture and can contribute to risk, but their direct role in plaque formation is not as strong or consistent as that of LDL. Clinically, reducing LDL is the main strategy to lower cardiovascular events, highlighting its central role in atherogenesis.
