Stents convencionais de aço inoxidável vs. cromo-cobalto: impacto clínico da liga metálica no cenário atual - registro InCor

ABSTRACT Stainless Steel versus Cobalt-ChromiumBare Metal Stents: Clinical Impact of theMetal Alloy in a “Real World” Scenario –InCor Registry Background: Years ago studies demonstrated that the use ofcobalt-chromium stents with thinner struts significantly reducedcoronary restenosis when compared to conventional stainlesssteel stents available at the time. Since then, stents with struts< 100 µm and different metal alloys are available for clinicaluse. The objective of this study was to assess differences inthe clinical outcomes of patients undergoing percutaneouscoronary intervention (PCI) with thin strut stents and differentmetal alloys. Methods: Single center registry comparing theresults of patients undergoing PCI with stainless steel stents(n = 135) vs. cobalt-chromium bare metal stents (n = 181).The primary endpoint was the occurrence of major adversecardiac events (MACE), defined by death, acute myocardialinfarction (AMI) or target vessel revascularization (TVR) in thelate follow-up.
