          Abstract

          INTRODUÇÃO: Considerado um fármaco com adequado perfil de eficácia e segurança no tratamento da síndrome coronária aguda sem supradesnivelamento do segmento ST, o fondaparinux, utilizado de forma isolada, associa-se a maior ocorrência de complicações trombóticas durante a realização de procedimentos coronários invasivos, requerendo a adição de agente com atividade anti-IIa. Este estudo teve como objetivo avaliar a eficácia e a segurança da intervenção coronária percutânea (ICP) em pacientes admitidos com diagnóstico de síndrome coronária aguda sem supradesnivelamento do segmento ST, previamente tratados com fondaparinux. MÉTODOS: Registro prospectivo, controlado, envolvendo 127 pacientes consecutivos submetidos a estratificação invasiva precoce na vigência de fondaparinux, com suplementação de heparina não-fracionada intravenosa na dose de 85 U/kg no momento da ICP. RESULTADOS: A taxa do desfecho primário, composto por morte, infarto agudo do miocárdio, acidente vascular encefálico, trombose de stent ou revascularização miocárdica de urgência, foi de 3,2%. A incidência acumulada de sangramento grave e complicações vasculares foi de 3,2%. Não houve casos de trombose do cateter-guia ou oclusão abrupta do vaso. CONCLUSÕES: A ICP em pacientes com síndrome coronária aguda em uso de fondaparinux associa-se a baixas taxas de eventos cardiovasculares adversos isquêmicos e de complicações hemorrágicas graves. A suplementação com heparina não-fracionada durante o procedimento invasivo elimina o risco de trombose do cateter.

          BACKGROUND: Fondaparinux is considered an agent with a well-established safety and efficacy profile in the treatment of non-ST segment elevation acute coronary syndromes, but when used alone, is associated to a higher incidence of thrombotic complications during invasive coronary procedures, requiring the supplementation of an anti-IIa agent. This study aimed to evaluate the efficacy and safety of percutaneous coronary intervention (PCI) in patients with non-ST segment elevation acute coronary syndromes previously treated with fondaparinux. METHODS: Prospective, controlled registry enrolling 127 consecutive patients submitted to an early invasive stratification during treatment with fondaparinux, with supplementation of intravenous unfractionated heparin at a dose of 85 U/kg at the time of PCI. RESULTS: The rate of the composite primary endpoint including death, acute myocardial infarction, stroke, stent thrombosis or emergency myocardial revascularization was 3.2%. The cumulative incidence of major bleeding and vascular complications was 3.2%. There were no cases of guide-catheter thrombosis or abrupt vessel closure. CONCLUSIONS: PCI in patients with acute coronary syndromes receiving fondaparinux is associated with a low rate of major adverse cardiovascular ischemic events and severe hemorrhagic complications. Supplementation of unfractionated heparin during the invasive procedures eliminates the risk of catheter-related thrombosis.
