A case of painless anteroseptal and high lateral wall infarction presenting as cardiogenic shock with pulmonary oedema 24 hours after childbirth complicated by severe post partum haemorrhage with a coagulation defect, is reported. Coronary angiography performed one month later was normal, with a negative ergometrine provocation test. The authors review five previous reports in the medical literature, and discuss the possible physiopathological mechanisms which, alone or in association could have operated in the reported case.
