Is statin therapy safe for pregnant women?
The long-standing prohibition on statin use during pregnancy has been reconsidered, opening the door for broader clinical discussions between cardiologists and expectant mothers. Laxmi Mehta, MD, a professor of medicine and section director of preventative cardiology and women's cardiovascular health at The Ohio State University Wexner Medical Center, emphasized the importance of these conversations in an interview with Cardiovascular Business.
For years, statins carried a U.S. Food and Drug Administration (FDA) "black box" warning due to concerns about teratogenicity based on animal studies involving rats and rabbits, which showed potential congenital malformations. However, human studies have since provided more clarity. While some data indicate possible associations with low birth weight or preterm labor, congenital malformations have not been confirmed as a significant risk factor in statin-exposed pregnancies. The FDA lifted the black box warning on statins in 2021.
With the increasing prevalence of maternal obesity and rising age of pregnancy, the cardiovascular health among women of childbearing age has become a growing concern. Mehta highlighted that atherosclerotic cardiovascular disease (ASCVD) affects approximately 1.4% of women in this demographic. Additionally, familial hypercholesterolemia (FH), a genetic condition impacting cholesterol levels, is underdiagnosed and undertreated in women, further necessitating effective lipid management strategies.
"They need statin therapy. These women need to improve their overall cardiovascular health and prevent events," Mehta explained.
She said the regulatory change underscores the necessity of shared decision-making between clinicians and patients.
"If a patient has a preexisting cardiovascular condition, we don't need to say, 'no, you can't get pregnant because you can't be on a statin.' We can say, 'let's work with you and we can do it,'" Mehta explained.
This shift in approach allows for individualized care plans, particularly for patients with severe lipid disorders such as homozygous FH. The emphasis now is on informed discussions that consider the benefits of statin therapy against potential risks, ensuring that women are not unduly discouraged from pregnancy due to cardiovascular concerns.
Ultimately, she said the medical community is moving towards a more nuanced understanding of statins in pregnancy, allowing for better treatment options and improved maternal and fetal outcomes.
