[Acute myocardial infarction during the second trimester of pregnancy]

Acute myocardial infarction during pregnancy is a very rare event. It occurs from 1 per 10,000 to 1 per 30,000 deliveries. Diagnosis of myocardial ischaemia is difficult because of typical complaints in pregnancy such as breathlessness and pain in chest. Its first recognisable symptom is very often loss of consciousness and cardiac death. We present the case of a 36-year-old woman with cardiac arrest in the second trimester of pregnancy. The defibrillation was applied four times with power ranging from 150 J to 200 J. Acute myocardial infarction was diagnosed on the basis of biochemical and electrocardiological examinations. Pharmacological treatment consisted of adrenalin, lidocaine, dopamine, heparin, insulin and cordarone. Uncomplicated pregnancy and delivery by caesarean section is described. A review of literature follows.

Although myocardial infarction is a rare complication of pregnancy, it always should be taken in consideration, especially in case of multipara older than 32, suffered from hypercholesterolemia or diabetes, treated with beta-mimetics or ergot alkaloid.
