Fracción aminoterminal del propéptido natriurético cerebral y troponina ultrasensible en el dolor torácico agudo de origen incierto. Un subestudio del estudio PITAGORAS
Resumen Introduccion y objetivos La troponina ultrasensible ha mejorado el diagnostico del sindrome coronario agudo en los pacientes que se presentan con dolor toracico y troponina convencional normal. Nuestro objetivo es analizar si la fraccion aminoterminal del propeptido natriuretico cerebral aporta informacion adicional. Metodos Se estudio a 398 pacientes, incluidos en el estudio PITAGORAS, que acudieron a urgencias por dolor toracico con troponina convencional normal en dos muestras seriadas (a la llegada y a las 6-8 h). Se midio de forma centralizada la troponina T ultrasensible en las dos muestras y la fraccion aminoterminal del propeptido natriuretico cerebral en la segunda. Los obj…
N-terminal Pro-brain Natriuretic Peptide and High-sensitivity Troponin in the Evaluation of Acute Chest Pain of Uncertain Etiology. A PITAGORAS Substudy
Abstract Introduction and objectives High-sensitivity troponin assays have improved the diagnosis of acute coronary syndrome in patients presenting with chest pain and normal troponin levels as measured by conventional assays. Our aim was to investigate whether N-terminal pro-brain natriuretic peptide provides additional information to troponin determination in these patients. Methods A total of 398 patients, included in the PITAGORAS study, presenting to the emergency department with chest pain and normal troponin levels as measured by conventional assay in 2 serial samples (on arrival and 6 h to 8 h later) were studied. The samples were also analyzed in a central laboratory for high-sensi…
