Lipoprotein(a) [Lp(a)]

Your standard lipid panel measures LDL cholesterol. It doesn’t measure Lp(a). Yet elevated Lp(a) affects roughly one in five people worldwide and substantially increases risk of heart attack, stroke, and aortic valve disease. Unlike LDL cholesterol, Lp(a) levels are almost entirely determined by your genes. Diet, exercise, and most medications barely move it.

Decades of genetic and epidemiological research confirm that Lp(a) is a causal risk factor for cardiovascular disease. Mendelian randomization studies show that people born with genetic variants for lower Lp(a) have proportionally lower rates of coronary artery disease, peripheral artery disease, and calcific aortic stenosis. The risk is continuous, with no clear safe threshold.

Yet most people have never had their Lp(a) measured. Most doctors don’t order it routinely. And until recently, no approved therapies existed to lower it substantially.

The landscape is changing. New RNA-targeted therapies can reduce Lp(a) by 80% or more. Large outcomes trials are underway. Guidelines increasingly recommend measuring Lp(a) at least once in every adult. The articles below provide a comprehensive guide for understanding this overlooked risk factor and making informed decisions about testing, monitoring, and management.
