Association Between Lipoprotein Particles and Atherosclerotic Events in Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD), the most common cause of chronic liver disease, ¹ is independently associated with increased risk of cardiovascular disease (CVD), which is the leading cause of mortality in patients with NAFLD. ² This is likely caused by the centrality of the liver in lipid homeostasis. Prior cross-sectional studies have shown that NAFLD is associated with perturbations in lipid profile and atherogenic lipoprotein subparticles. ³ Although statins improve lipid profile and CVD-associated mortality, residual CVD risk has been demonstrated in major statin trials. ^{4 , 5} A key contributor to this residual risk is the limited ability of the standard lipid profile to precisely quantify atherogenic lipoprotein subparticles, such as small dense low-density lipoprotein (sdLDL), which might confer higher atherogenic risk. There are currently no studies evaluating the longitudinal impact of sdLDL on atherosclerotic events in NAFLD. Thus, we conducted a prospective study in patients with histologically confirmed NAFLD to better define the relationship among NAFLD, residual CVD risk, and sdLDL.
