|- Brief summary||The MISSION! Intervention Study is a prospective randomized study comparing non-coated, thin strut, cobalt chromium stents (Vision TM) and sirolimus eluting stents (Cypher TM) for the treatment of patients with acute myocardial infarction. |
300 patients will be randomized and treated by primary percutaneous coronary intervention with stent implantation. All patients will have angiographic follow-up at 9 months to assess the primary endpoint with Quantitative Coronary Angiography. In all patients, IVUS will be performed post-intervention and at 9 months follow-up to assess acute and late incomplete stent apposition and neointimal volume.
Moreover fractional flow reserve will be measured at 9 months to assess functional stent patency. At 12 months major adverse events will be counted and analysed according to life table methods.
Clinical and angiographic data will be analyzed according to the principle of intention-to-treat and evaluable group analyses. End-point variables will be presented by means of 95% confidence intervals.
