[Myocardial infarction due to spontaneous coronary dissection during the postpartum period].
The authors report the case of a 34 year old woman, admitted to hospital because of myocardial infarction two months after delivery of her fifth child. The infarction was caused by spontaneous dissection of the left main coronary and left anterior descending arteries. Twenty-three months later, the patient was well with medical therapy. This case is an example of spontaneous post-partum coronary dissection which is the commonest cause of infarction occurring in that period. The physiopathology of this complication is not fully understood. The prognosis is poor, lethal in two thirds of cases. However, it must be emphasised that coronary dissection may regress spontaneously. Patients were previously referred systematically for surgery, but now it is usually reserved for cases with persistent myocardial ischaemia despite medical therapy. Angioplasty may be preferred despite the risks and may be successful in some cases.
