Gedetailleerde beschrijving
The question of whether DES are safe, has become an area of considerable interest and controversy with the publication of a relatively small randomized trial (BASKET-LATE), an observational study and a meta-analysis reporting increased rates of ST, MI, and death with DES compared to BMS. The motivating factor was the presentation of a meta-analysis at the European Society of Cardiology meeting in Barcelona in September 2006, which suggested an increase in the risk of death and MI following implantation of sirolimus-eluting stents.
The major issue in these meta-analyses is that they were limited either by small sample sizes, duration of follow-ups, lack of access to source data, or by using landmark analyses that excluded events in first 6 months.
Moreover, the largest meta-analysis of DES vs. BMS and SES vs. PES published recently in The Lancet by Settler et al performed a network analyses with a mixed-treatment comparison of 38 randomized trials (18023 patients) with a follow-up of up to 4 years. This analysis again confirmed that DES and BMS were associated with similar rates of overall and cardiac mortality Regarding "real world" population, two observational registries recently published, i.e. the Western Denmark Heart Registry and the SCAAR (Swedish Coronary Angiography and Angioplasty Registry) confirmed no difference in the hard endpoints between DES and BMS. However, it must be remembered that these studies are observational and at best are hypothesis-generating.
Some autoptic studies have observed an incomplete healing following first generation DES implantation as compared to BMS; in these series late ST was associated with more delayed healing compared with patent DES. Among all the unsettled or not fully tested indications for usage of DES, ACS is most probably the one where implantation of BMS remains the most used approach because of the uncertainty regarding the thrombotic risk of DES in a thrombus rich milieu and the low risk for restenosis following BMS implantation in patients with acute MI. Despite encouraging results from currently published data with DES, well designed and appropriately powered clinical trials are warranted in order to establish long term safety and efficacy (incremental advantage over BMS) of DES in this setting. Moreover, recently it was reported that exposed struts were more frequent with first generation DES, and percent neointimal hyperplasia(NIH) area was smaller in ACS lesions than in non-ACS lesions.
For this specific purpose, we will evaluate, using OCT, complete neointimal coverage of Everolimus- vs. Zotarolimus Eluting Stent implanted in the novo lesions on native coronary arteries in patients with ACS. Rates of exposed and/or malaposed stent struts will be analysed and neointimal hyperplasia (NIH) area will be calculated.

Evaluate the completeness of neointimal coverage following stent implantation (everolimus vs. zotarolimus-eluting stent) in patients with ACS.
The degree of neointimal coverage will be assessed using optical coherence tomography (OCT) calculating the rate of exposed stent struts in the study stents.
