JCL roundtable-Lipoprotein(a): The emerging risk factor.
Lipoprotein(a), or Lp(a), is a major risk factor for atherothrombotic events along with low-density lipoprotein cholesterol and, inversely, high-density lipoprotein cholesterol. Lp(a) also contributes to the progression of calcific aortic stenosis and to the rare occurrence of arterial thrombotic strokes without atherosclerosis in children and younger women. Much has been learned about the inheritance of Lp(a) levels and the relationship between apolipoprotein(a) structure and function. Recent work suggests an intriguing interaction between oxidized phospholipids on Lp(a) and inflammatory interleukin-1 genotypes. New pharmaceutical approaches with antisense and RNA interference technology may achieve up to 90% lowering of Lp(a). This Roundtable includes practical considerations for clinically measuring and responding to Lp(a) levels.
