Relationship of oxidized phospholipids on apolipoprotein B-100 particles to race/ethnicity, apolipoprotein(a) isoform size, and cardiovascular risk factors: results from the Dallas Heart Study.

abstract：BACKGROUND:Chronic heart failure is associated with endothelial dysfunction including impaired endothelium-mediated, flow-dependent dilation (FDD). Since endothelial function is thought to play an important role in coordinating tissue perfusion and modulating arterial compliance, interventions to improve endothelial dy...
