What this trial studies

This study examines how breastfeeding affects lipid profiles and cardiovascular risk markers in women diagnosed with familial hypercholesterolemia (FH) compared to those without FH. Women who are pregnant or planning pregnancy will be recruited from Norway, the Netherlands, and the Czech Republic, and will participate in multiple study visits from late pregnancy through the first year postpartum. Blood samples and data on health, lifestyle, and diet will be collected, along with measurements of statin transfer into breast milk. The goal is to better understand the implications of breastfeeding on cholesterol management in women with FH.

Who should consider this trial

Good fit: Ideal candidates include women aged 18 and older who are pregnant or planning pregnancy, with a confirmed diagnosis of familial hypercholesterolemia or without any history of hypercholesterolemia.

Not a fit: Patients who have known pre-pregnancy hypercholesterolemia or a history of atherosclerotic cardiovascular disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into managing cholesterol levels and cardiovascular risks in women with familial hypercholesterolemia during and after pregnancy.

How similar studies have performed: Limited studies have explored the effects of breastfeeding on lipid profiles in women with familial hypercholesterolemia, making this approach relatively novel.
