Cardiovascular Medications in Pregnancy: A Primer.

Cardiovascular disease and cardiovascular disease-related disorders remain among the most common causes of maternal morbidity and mortality in the United States.

Obstetricians and cardiologists must familiarize themselves with the pharmacokinetics of the most commonly used cardiovascular medications in pregnancy and how these medications respond to the physiologic changes related to pregnancy, embryogenesis, and lactation.
