Measuring Lipoprotein(a) in Clinical Practice to Reduce the Burden of Cardiovascular Disease? Still Work in Progress.
J Osei et al, CDC Blog Post, August 9, 2022
A recent review suggested that the use of lipoprotein (Lp) (a) measurement in clinical practice may have clinical and economic benefits for patients, healthcare systems, and society as a whole. However, widespread adoption of Lp(a) measurement in the general population has been hindered by limited treatment options targeting Lp(a) reduction.
Impact of a Population Genomic Screening Program on Health Behaviors Related to Familial Hypercholesterolemia Risk Reduction.

We conducted a retrospective cohort study of MyCode participants with an FH risk variant beginning 2 years before disclosure until January 16, 2019. We analyzed lipid-lowering prescriptions (clinician behavior), medication adherence (participant behavior), and LDL (low-density lipoprotein) cholesterol levels (health outcome impact) pre- and post-disclosure. Data were collected from electronic health records and claims. Despite disclosure of an FH risk variant, nonprescribing and nonadherence to lipid-lowering therapy remained high. However, when clinicians intensified medication regimens and participants adhered to medications, lipid levels decreased.
Everyone deserves a diagnosis
The Family Heart Foundation, July 18, 2022
“Runs in the family” is not a diagnosis- Over the past 10 years, we have heard from thousands of people who have heart disease or had a stroke caused by an inherited cholesterol disorder. Unfortunately, they did not learn of their genetic condition until it was too late. The damage was done. They were told that heart disease or high cholesterol “runs in the family” but were never given the name of the genetic cause that leads to so much heartache across generations. We believe families deserve a diagnosis so they can get the care they deserve. That is why we have launched this campaign. We hope you will join us to help reach people who have never heard of FH or elevated Lipoprotein(a).

High levels of lipoprotein (a) increase your likelihood of having a heart attack, a stroke, and aortic stenosis, especially if you have familial hypercholesterolemia or signs of coronary heart disease. High Lp(a) levels, defined as greater than 50 mg/dL (125 nmol/L),3 are common. Median Lp(a) levels vary by race and sex.4 High Lp(a) is seen in people of all races and ethnicities but appears to be more common in Black people.4 Many people with high Lp(a) have no symptoms. However, your doctor may suspect that you have high Lp(a) if you have one or more risk factors such as family history, familial hypercholesterolemia, peripheral artery disease and others.
