RESUMO

Objetivo: Los objetivos del estudio son evaluar el rendimiento diagnóstico de la troponina cardiaca T de alta sensibilidad (TnTc-hs) en pacientes con sospecha de síndrome coronario agudo sin elevación del segmento ST (SCASEST), confirmar si permite acortar el tiempo hasta el diagnóstico y analizar las consecuencias clínicas derivadas de su utilización. Método: Se trata de un estudio observacional, longitudinal y prospectivo, realizado en 5 servicios de urgencias hospitalarias. Se incluyó de forma consecutiva a los pacientes que acudían por dolor torácico sospechoso de SCASEST. El manejo del paciente y el tratamiento aplicado siguieron los protocolos internos basados en las guías de consenso de la Sociedad Europea de Cardiología. Se realizaron determinaciones seriadas de Tnc convencional (4ªG) y de TnTc-hs. Resultados: Se incluyó en el estudio a 351 pacientes. El diagnóstico final de infarto agudo de miocardio (IAM) se estableció en 77 pacientes del total, angina inestable en 102 y 172 fueron pacientes diagnosticados como sin síndrome coronario agudo. Los valores de TnTc-hs estaban por encima del p99 en un alto número de pacientes sin IAM. En la determinación inicial del paciente, la sensibilidad diagnóstica de la TnTc-hs fue significativamente superior a la de la TnTc 4ªG (87,0 vs. 42,9%), lo que comportó un valor predictivo negativo del 95,1%. Conclusiones: La TnTc-hs mejora el rendimiento diagnóstico al compararla con el ensayo de Tnc convencional, acorta el tiempo hasta el diagnóstico y reconoce mayor número de pacientes con IAM más pequeños


Objective: To assess the diagnostic performance of high-sensitivity troponin T (hs-TnT) in patients with suspected non-ST elevation acute coronary syndrome (NSTE-ACS); confirm whether it shortens the time to diagnosis; and analyze the clinical consequences derived from its use. Method: A prospective, longitudinal observational study was carried out in 5 emergency care departments. Patients seen for chest pain with suspected of NSTE-ACS were consecutively included. Patient care followed the internal protocols of the center, based on the consensus guidelines of the European Society of Cardiology. Serial conventional cardiac troponin (cTn) and hs-TnT determinations were made. Results: A total of 351 patients were included in the study. A final diagnosis of acute myocardial infarction (AMI) was established in 77 patients, with unstable angina in 102, and no acute coronary syndrome in 172 patients. The hs-TnT values were above percentile 99% in a large number of patients without AMI. In the initial determination, the diagnostic sensitivity of the hs-TnT was significantly greater than that of cTn (87.0% vs. 42.9%), which led to a negative predictive value of 95.1%. Conclusions: High-sensitivity troponin T improves diagnostic performance compared with conventional troponin assay, shortens the time to diagnosis, and identifies a larger number of patients with smaller myocardial infarctions

RESUMO

En los últimos años ha habido novedades significativas en las estrategias de manejo yen los fármacos utilizados en el tratamiento del síndrome coronario agudo (SCA). Hasta hoy, las guías de práctica clínica recomendaban el uso de doble terapia antiagregante con aspirina y clopidogrel. Dos nuevos inhibidores del receptor P2Y12 (prasugrel y ticagrelor) han sido aprobados como tratamiento del SCA, y muestran una inhibición plaquetaria más rápida y más eficaz. Esta incorporación a la práctica clínica implica un cambio importante en el manejo de estos pacientes en su fase aguda. Se revisa brevemente la fisiopatología del proceso trombótico, los inicios de la antiagregación y los ensayos clínicos llevados a cabo con estos nuevos fármacos, así como su utilización en los servicios de urgencias (AU)


New pharmacologic strategies for managing acute coronary syndrome (ACS) have emerged in recent years. Clinical guidelines continue to recommend dual antiplatelet therapy with aspirin and clopidogrel. Two recently approved P2Y12inhibitors, prasugrel and ticagrelor, have been shown to act faster and more effectively in treating ACS. These drugs mark an important turning point in the emergency management of ACS. We briefly review the pathophysiology of the thrombotic process and recall the early history of antiplatelet therapy. We explain the results of clinical trials of these new drugs and their use in the emergency department (AU)
