ABSTRACT
Background: Data from over 4 decades have reported a higher incidence of silent infarction among patients with diabetes mellitus (DM), but recent publications have shown conflicting results regarding the correlation between DM and presence of pain in patients with acute coronary syndromes (ACS). Objective: Our primary objective was to analyze the association between DM and precordial pain at hospital arrival. Secondary analyses evaluated the association between hyperglycemia and precordial pain at presentation, and the subgroup of patients presenting within 6 hours of symptom onset. Methods: We analyzed a prospectively designed registry of 3,544 patients with ACS admitted to a Coronary Care Unit of a tertiary hospital. We developed multivariable models to adjust for potential confounders. Results: Patients with precordial pain were less likely to have DM (30.3%) than those without pain (34.0%; unadjusted p = 0.029), but this difference was not significant after multivariable adjustment, for the global population (p = 0.84), and for subset of patients that presented within 6 hours from symptom onset (p = 0.51). In contrast, precordial pain was more likely among patients with hyperglycemia (41.2% vs 37.0% without hyperglycemia, p = 0.035) in the overall population and also among those who presented within 6 hours (41.6% vs. 32.3%, p = 0.001). Adjusted models showed an independent association between hyperglycemia and pain at presentation, especially among patients who presented within 6 hours (OR = 1.41, p = 0.008). Conclusion: In this non-selected ACS population, there was no correlation between DM and hospital presentation without precordial pain. Moreover, hyperglycemia correlated significantly with pain at presentation, especially in the population that arrived within 6 hours from symptom onset. .
Fundamento: Dados de mais de 4 décadas relataram maior incidência de infarto silencioso entre os pacientes com diabetes mellitus (DM), mas publicações recentes mostraram resultados conflitantes quanto à correlação entre DM e presença de dor em pacientes com síndromes coronárias agudas (SCA). Objetivo: Nosso objetivo principal foi analisar a associação entre dor precordial e DM na chegada ao hospital. Análises secundárias avaliaram a associação entre hiperglicemia e dor precordial na apresentação, e o subgrupo de pacientes que se apresentaram em até 6 horas após o início dos sintomas. Métodos: Analisamos um registro prospectivo de 3.544 pacientes com SCA internados em unidade coronária de um hospital terciário. Desenvolvemos modelos multivariados para ajustar potenciais fatores de confusão. Resultados: Os pacientes com dor precordial eram menos propensos a ter DM (30,3%) do que aqueles sem dor (34,0 %, p não ajustado = 0,029), mas essa diferença não foi significativa após ajuste multivariado, para a população global (p = 0,84), e para o subgrupo de pacientes que se apresentaram dentro do período de 6 horas após o início dos sintomas (p = 0,51). Em contraste, a dor precordial era mais provável entre os pacientes com hiperglicemia (41,2% vs. 37,0% sem hiperglicemia, p = 0,035) na população total, e também entre aqueles que se apresentaram no período de 6 horas (41,6% vs. 32,3%, p = 0,001). Modelos ajustados mostraram uma associação independente entre hiperglicemia e dor na apresentação, especialmente entre os pacientes que se apresentaram no período de até 6 horas (OR = 1,41, p = 0,008). Conclusão: Nesta população não-selecionada com SCA, não houve correlação entre DM e a ...

There are several excellent alternatives to warfarin on the horizon for atrial fibrillation. Results from the trials, as well as pharmacokinetic data from the edoxaban studies, suggest that dose selection, based on pharmacokinetic and pharmacodynamic properties, is a critical component in the development of novel anticoagulants. Greater flexibility in dosing with edoxaban and the opportunity for dose adjustment throughout the ENGAGE AF-TIMI 48 trial may be advantageous in the competitive field of novel oral anticoagulants.
Existen excelentes alternativas al tratamiento con warfarina en el campo de la fibrilación auricular. Los resultados de los ensayos con RE-LY, ROCKET-AF y ARISTOTLE, así como los datos fármaco cinéticos obtenidos en estudios con edoxaban, sugieren que la selección de la dosis, basada en propiedades fármaco cinéticas y fármaco dinámicas, es un componente crítico en el desarrollo de nuevos anticoagulantes. Una mayor flexibilidad en establecer la dosis de edoxaban y la oportunidad de ajustar la dosis mediante ENGAGE AF-TIMI 48, puede constituir una ventaja en el campo de los nuevos anticoagulantes orales.
