Acute ST-elevation myocardial infarction in early puerperium due to severe left main coronary stenosis in a woman with familial hyperlipidaemia : online article - case report

Abstract

Acute myocardial infarction (AMI) is a rare but often catastrophic event during pregnancy, delivery or puerperium, leading to a high mortality rate. It has different pathogenic mechanisms, such as atherosclerosis, vasospasm, thrombosis and coronary dissection. Although MI has been reported in pregnant women at all stages of pregnancy and postpartum, it occurs more commonly in the third trimester and most commonly involves the anterior wall. Evidence suggests that pregnancy itself is an independent risk factor for MI, conferring a three- to four-fold higher risk than that of nonpregnant women matched for age, possibly due to the unique physiological changes required to meet the demands of a growing foetus. We report a case of a 27-year-old woman with familial hyperlipidaemia presenting with myocardial infarction six days after caesarean delivery, secondary to severe left main coronary stenosis (LMCA), who was treated with emergency coronary artery bypass grafting (CABG).
