 The purpose of this trial is to compare the long-term effects on MI and total mortality of BMS vs DES. The trial will recruit 8000 patients from 8 Norwegian hospitals. The patients will be randomized to treatment with BMS or DES. Clinical events will be registered for 5 years after treatment. The study hypothesis is that there is no difference in the risk of death or myocardial infarction after treatment with BMS vs DES. The trial is initiated and run by university researchers and is sponsored by not-for-profit organizations.
