RESUMEN
La cardiopatía isquémica representa a nivel mundial una de las principales causas de mortalidad y de costo para los sistemas nacionales de salud. El número de consultas anuales en los Estado Unidos por dolor torácico en los servicios de urgencias llega a los 5 millones. El número de muertes anuales por infarto agudo al miocardio llega a 750,000. El diagnóstico de síndrome coronario agudo puede ser difícil en las primeras horas de atención del paciente, hecho que lo pone en riesgo de complicaciones. El tiempo es miocardio. El objetivo de la presente revisión es hacer un análisis de la literatura para que, con medicina basada en evidencia, se haga uso correcto de las herramientas diagnósticas disponibles, logrando un diagnóstico de síndrome coronario agudo lo más rápido posible. No se discutirán los casos de los pacientes con dolor torácico agudo y cambios electrocardiográficos como supradesnivel del segmento ST y/o bloqueo de rama izquierda de reciente aparición, ya que estos pacientes deben de ser manejados como infarto agudo al miocardio en evolución, tema que requiere una revisión aparte.
