Inherited High Cholesterol Linked to Higher Preeclampsia

What did the study find about inherited cholesterol and preeclampsia?

The study compared 484 women with familial hypercholesterolemia, or FH, with 968 matched controls in the Netherlands and Norway. Participants were aged 40 or older. The reported preeclampsia proportions differed by four percentage points; these historical findings should not be interpreted as a personalized prediction for a current pregnancy. Researchers found no statistically significant differences in the other reproductive outcomes examined.

A separate Norwegian registry study published in Atherosclerosis in 2025 provides supporting context. It examined 3,869 pregnancies among women with genetically confirmed FH and also identified an association with preeclampsia. However, it did not find an excess of adverse outcomes in offspring overall. Together, the studies suggest a relationship worth investigating, while leaving open whether cholesterol itself, accompanying cardiovascular characteristics, or other factors explain it.

Why does preeclampsia require attention during and after pregnancy?

Preeclampsia usually develops after 20 weeks of pregnancy and involves high blood pressure with evidence of organ dysfunction. Findings may include protein in the urine, abnormal kidney or liver function, or low platelets. Some people initially feel well, making routine prenatal blood-pressure checks essential. A cholesterol measurement cannot diagnose or exclude the condition. [ACOG guidance on preeclampsia](https://www.acog.org/womens-health/faqs/preeclampsia-and-high-blood-pressure-during-pregnancy)

A persistent or worsening headache, vision changes, difficulty breathing, or pain on the right side beneath the ribs requires immediate medical attention during pregnancy or after childbirth. Postpartum preeclampsia can occur even when blood pressure was normal during pregnancy. These symptoms should prompt urgent assessment rather than waiting for the next routine appointment.

The implications also extend beyond delivery. A history of preeclampsia is associated with greater subsequent risk of high blood pressure, heart attack, stroke, and kidney disease. Recording pregnancy complications in the long-term medical record helps clinicians assess cardiovascular health alongside cholesterol, smoking, diabetes, and other established risk factors.

How should women with familial hypercholesterolemia plan pregnancy?

FH produces lifelong elevation of LDL cholesterol and increases the risk of premature cardiovascular disease. Managing it around pregnancy therefore requires balancing the mother's underlying cardiovascular risk with medication safety. The National Lipid Association's updated clinical consensus supports individualized counseling and consideration of care involving both lipid specialists and pregnancy clinicians, ideally before conception. A plan should address pregnancy, breastfeeding, and the eventual resumption or adjustment of treatment. [National Lipid Association clinical consensus](https://www.lipidjournal.com/article/S1933-2874%2826%2900010-3/fulltext)

Statin decisions deserve particular care. The FDA advises discontinuation in most pregnancies but allows individualized consideration for patients at very high cardiovascular risk. Anyone who becomes pregnant while taking a statin should promptly contact the prescriber; the FDA states that inadvertent exposure early in pregnancy is unlikely to harm the developing fetus. Its guidance also advises against breastfeeding while taking a statin.

The new association does not establish a treatment for preventing preeclampsia. Current dyslipidemia guidance permits consideration of statins during selected high-risk pregnancies after an individualized benefit-risk discussion, but this is distinct from prescribing them to prevent pregnancy complications. The study should inform clinical conversations, rather than trigger patients to start, stop, or substitute medicines on their own.
