A 49-year-old female was admitted to our hospital because of an acute anteroseptal wall myocardial infarction. The patient had no previous coronary artery or heart disease. Chest pain with radiation to the left shoulder associated with severe transpiration and nausea had been present since one hour before presentation. After transportation to the catheterisation laboratory she underwent a primary percutaneous coronary intervention (PCI) procedure of the left anterior descending coronary artery which was occluded after the first septal branch. A bare metal stent (Vision, Guidant) was implanted. The other coronary arteries showed no significant lesions.
