Ischemic heart disease in pregnancy

While ischemic heart disease in reproductive-age women is rare, cardiac disease is a leading cause of maternal mortality. In turn, coronary artery disease is one of the most common causes of maternal cardiac death. The incidence of coronary artery disease in pregnancy may be rising due to the increasing prevalence of comorbid risk factors. Diagnosis and clinical management of ischemic cardiac disease is largely similar in the pregnant and non-pregnant patient, and the majority of medications and diagnostic and interventional procedures are compatible with pregnancy with a few important exceptions. Care for ischemic cardiac disease in pregnancy may be suboptimal because: (1) diagnosis is delayed because many symptoms of ischemic cardiac disease are common in pregnancy, (2) a diagnostic workup is insufficiently thorough, and/or (3) consultants may be hesitant to perform diagnostic and interventional procedures in obstetric patients. Obstetric providers should be aware of the possibility of ischemic cardiac disease in pregnancy, particularly in patients with comorbid risk factors. If ischemic cardiac disease is suspected, a thorough workup should be performed.
