What is lipoprotein(a) cholesterol, or Lp(a)? And can you lower yours?

The Conversation · · 877 words · By Kirsten Adlard; Lauren Ball

The article explains the role of lipoprotein(a), a genetically determined cholesterol particle that increases the risk of cardiovascular disease. It discusses the limitations of current treatments, the development of new 'gene silencing' drugs, and the current guidelines for testing.
