Popis: AimsThe purpose of the present study was to assess the incidence, predictors and long term prognosis of stent edge dissections identified by (OCT) after the implantation of bare metal (BMS) and drug eluting stents (DES). Methods and ResultsWe studied 74 patients who underwent percutaneous coronary intervention (PCI) because of an acute coronary syndrome. Edge dissections were found in 29 of 74 patients (39.1%). Independent predictors of edge dissections were: the presence of ST-elevation myocardial infarction (STEMI) (P=0.005, odds ratio 11.78; 95% Cl 2.06-67.10), the small reference lumen diameter (P=0.009, odds ratio 0.11; 95% Cl 0.02-0.58) and the short stents implanted (P=0.013, odds ratio 0.83; 95% Cl 0.72-0.96). During a follow-up period of 25.69.4 months 11 patients presented with at least one major adverse cardiac event. Event free survival was significantly decreased in patients with edge dissection with a flap thickness >0.31 mm compared to patients with thinner flap or without any dissection (P
