[Acute coronary syndrome during a cesarean section in a healthy young woman].

Acute coronary syndrome (ACS) during pregnancy and delivery is a rare event that is usually related to prior disease or family history. Factors that contribute to the appearance of ACS during delivery in women with healthy coronary arteries include high doses of drugs to suppress contractions or increase uterine muscle tone and cardiovascular instability of any kind. Clinical and electrocardiographic abnormalities (eg, ST segment depression) that are suggestive of ACS have been reported to occur during cesarean section but without subsequent enzyme or echocardiographic abnormalities.
