Postpartum acute myocardial infarction: a rare occurrence of uncertain etiology.
Two women who had an acute myocardial infarction during the early postpartum period are described, and the findings in nine other women previously reported on are summarized. Attention is called to the atypical nature of ischemic heart disease and myocardial infarction in these patients when compared with myocardial infarction during pregnancy and with ischemic heart disease in men. Postpartum infarcts most often occur in women in their 20s during their first pregnancy, frequently a pregnancy complicated by the preeclampsia-eclampsia syndrome, and are associated with a high mortality rate. In one of our patients and one patient previously reported on, the results of coronary arteriography were normal, suggesting that coronary arterial thromboembolism or spasm was a cause of the infarction. Because postpartum myocardial infarction may be unrelated to atherosclerotic narrowing, detailed angiographic studies in such patients appear warranted. These cases indicate the variety and complexity of ischemic heart disease in women.
