In pregnancy-associated chest pain, which management approach is prioritized in the ED?

• A. Involve obstetrics late after initial stabilization
• B. Minimize radiation exposure but ignore obstetric input
• C. Prioritize maternal and fetal safety; minimize radiation exposure; involve obstetrics early
• D. Rely on radiologic imaging only and avoid clinical assessment

Answer: (C)

In pregnancy-associated chest pain, the priority is to protect both mother and fetus while rapidly determining the cause. The most important steps are to stabilize the mother first because her status directly drives fetal well-being, then address fetal monitoring and obstetric considerations in parallel. This means initiating prompt resuscitation and continuous monitoring, providing oxygen as indicated, and correcting life-threatening issues without delay.

At the same time, bring obstetrics into the care plan early. Early obstetric input helps tailor the assessment and management to the pregnancy, guides decisions about fetal monitoring, possible obstetric interventions, and how imaging and treatments may affect both mother and fetus. Minimizing radiation exposure remains important, but it should never trump timely, accurate diagnosis; choose imaging modalities with the lowest reasonable exposure that still yield the needed information, and use shielding and alternative studies (like ultrasound or echocardiography) when appropriate.

Relying solely on imaging or delaying obstetric involvement would miss critical clinical signs and complicate management, while focusing only on clinical assessment without considering imaging could miss hidden etiologies. The balanced approach—prioritizing maternal and fetal safety, minimizing radiation exposure, and involving obstetrics early—best aligns with the needs of pregnancy-associated chest pain in the ED.
