Acute myocardial infarction during pregnancy is a rare disease, nevertheless in recent years its incidence is due to several factors increasing. In the pathogenesis the first place is not held unequivocally by coronary atherosclerosis. Also some other mechanisms are involved, one of them being the hypercoagulation state during pregnancy. From the therapeutic aspect the first place is held by achievement of reperfusion of the ischaemic heart muscle by opening of the infarcted artery which can be achieved by fibrinolytic treatment and nowadays by the method of first choice - coronary angioplasty - which can be performed in somer selected departments. The application of this method as safe and effective treatment is apparent also from the case-history of a 34 year old patient in the second trimester of pregnancy which is presented by the authors.
