“Lp(a) is important because it is more strongly associated with cardiovascular morbidity and mortality than many traditional lipids such as LDL cholesterol. For a long time, it didn't receive much attention. Elevated Lp(a) is common. Depending on what cut point you use, about one in every five individuals has an Lp(a) level in a range where there is increased risk. That's more than 1 billion people on our planet, and it has taken a while for the guidelines to recognize it.”
