Question 126
Small, dense LDL is most likely to interact with arterial walls, leading to deposition of cholesterol, and initiating or worsening atherosclerosis. Small, dense LDL is associated with more than a three-fold increase in the risk of coronary heart disease.
Large, buoyant LDL is less atherogenic than small, dense LDL.
The LDL phenotype A is normal. It is the so called 'B' pattern that is associated with increased risk.
Which of the following is most likely to interact with arterial walls, leading to deposition of cholesterol, and initiating or worsening atherosclerosis?
