dc.description.abstract | Background: High platelet reactivity (HPR) during therapy with acetylsalicylic acid (ASA) is a poor prognostic factor in acute coronary syndromes (ACS). The prevalence of HPR during ACS is greater than that reported in stable diseases. However, it is unclear whether this prevalence of HPR is a transient phenomenon or a characteristic of this high-risk population. Objective; The main objective is to compare the effects of ASA on platelet function in the initial and late phases of ACS in a single population. Secondary objectives are: correlation between the tests between themselves and the relationship between the tests and the variation of the inflammatory markers (C-reactive protein and interleukin-6). Methods: Seventy patients with non-ST segment elevation (NSTE) ACS in use of 100-200 mg of ASA per day for at least 7 days were prospectively studied. Platelet function was assessed in the first 48 hours and subsequently after 3 months using four methods: VerifyNow (TM) (VFN), whole blood platelet aggregation (WBPA) with arachidonic acid (AA) and collagen as agonists, and platelet function analyzer (PFA). The level of statistical significance considered was < 0.05. Results: According to the more specific methods (WBPA with AA and VFN), the incidence of HPR was significantly higher in the early phase than in the late phase: WBPA with AA: 31% versus 13%, p = 0.015; VFN: 32% versus 16%, p = 0.049. The other methods tested, which were less specific for ASA, did not show significant differences between phases. The correlation between the methods was weak or moderate (r ranging from 0.3 to 0.5, p < 0.05), and there were no significant associations between HPR and inflammatory markers. Conclusion: The prevalence of HPR during AAS therapy, assessed by specific methods for cyclooxygenase 1 (COX-1), is higher during the acute phase than in the late phase of NSTE ACS. | eng |
dc.description.abstract | Fundamento: A alta atividade plaquetária (AAP) durante a terapia com ácido acetilsalicílico (AAS) é fator de mau prognóstico nas síndromes coronarianas agudas (SCA). A prevalência de AAP durante a SCA é maior do que a relatada na doença estável. No entanto, não está claro se esta prevalência de AAP é um fenômeno transitório ou característica dessa população de alto risco. Objetivo: O objetivo principal é comparar, em uma mesma população, os efeitos do AAS sobre a função plaquetária nas fases inicial e tardia da SCA. Os objetivos secundários são: correlação entre os testes entre si e a relação entre os testes e a variação dos marcadores inflamatórios (proteína C reativa e interleucina-6). Métodos: Foram estudados prospectivamente 70 pacientes com SCA sem elevação de ST (SCSST) em uso de 100 a 200 mg de AAS por dia por pelo menos 7 dias. A função plaquetária foi avaliada nas primeiras 48 horas e 3 meses após por quatro métodos: VerifyNow™ (VFN), agregometria de sangue total (AST) com ácido araquidônico (AA) e colágeno como agonistas, e analisador de função plaquetária (PFA). O nível de significância estatístico considerado foi < 0,05. Resultados: A média de idade foi de 65 ±9,7 anos e 54% da população eram do sexo feminino. De acordo com os métodos mais específicos (AST com AA e VFN), a incidência de AAP foi significativamente maior na fase inicial, em relação à tardia: AST com AA 31% versus 13%, p = 0,015; VFN 32% versus 16%, p = 0,049. Os outros métodos testados, menos específicos para o AAS, não mostraram diferenças significativas entre as fases. A correlação entre os métodos foi fraca ou moderada (r variando de 0,3 a 0,5, p < 0,05), e não houve associações significativas entre AAP e marcadores inflamatórios. Conclusão: A prevalência de AAP durante a terapia com AAS, avaliada por métodos específicos para cicloxigenase 1 (COX-1), é maior durante a fase aguda do que na tardia da SCASST. | |
