"The most dangerous particle when it comes to heart disease and thrombotic stroke is genetically-determined, meaning your family gave it you.  Insurance companies have traditionally refused to pay to have it tested so most of the millions of people who have it are unaware.  It is called “Lp little a or Lp(a).

Lp(a) is a lipoprotein that is similar to LDL. It is very small, dense and dangerous. Like LDL, it contains an apo B molecule and a cholesterol rich lipid core. However, unlike LDL, Lp(a) has a unique sugar protein on its surface which makes it much more likely to cause blood clotting." - Dr. Alan Hopkins
