““Most people now have the ‘LDL-C is bad and HDL-C is good’ concept down pat. But there is more to the story. It is well established that not all LDL particles are created equal. Moreover, certain types of LDL have been shown to correlate with abnormal lipid profiles and promote atherosclerosis. As noted previously, the larger more buoyant LDL particles are less harmful than smaller ones. Small LDL particles reside in the circulation longer, have greater susceptibility to oxidative damage by free radicals, and more easily penetrate the arterial wall, contributing to atherosclerosis. No matter what your total LDL-C concentration, if you have relatively more small particles (referred to as Pattern B) it puts you at a several-fold higher risk for heart disease compared to people with larger LDL particles (Pattern A)[49]. And once again, this is independent of your LDL-C concentration.””
