Percutaneous coronary intervention for myocardial infarction during pregnancy: a new trend?

Recent studies report that American women are increasingly delaying their first births. While the proportion of births in older women has been increasing, there is also increased prevalence of cardiovascular risk factors and complications of pregnancy with increasing maternal age. We present 2 cases of acute myocardial infarction occurring during pregnancy. The mothers were both over 35 years old, and had significant risk factors for coronary disease. Both were found to have atherosclerotic coronary lesions, and were managed with coronary intervention with successful reperfusion. One woman successfully delivered a healthy infant at term. The other had a spontaneous abortion shortly after discharge from the hospital. Given current demographic trends, it is likely that such cases will be more commonly seen.
