RESUMEN

Se calcula que en los Estados Unidos de Norteámerica ocurren alrededor de 300,000 nuevos casos de isquemia cerebral transitoria (ICT) por año1 y alrededor de 15 a 20% de los pacientes con un infarto cerebral tienen historia de ICT2. En los últimos años se ha de-mostrado que la isquemia cerebral transitoria (ICT) es un fuerte predictor a corto plazo de infarto cerebral, enfermedad cardiovascular y muerte3. En teoría es- tos eventos de isquemia transitoria dan la oportunidad de investigar el mecanismo de producción de la isquemia y de iniciar tratamientos preventivos en un paciente integro. Sin embargo, en la práctica, estos episodios son frecuentemente poco reconocidos, sub y sobre diagnosticados, lo que implica la no modifi-cación de factores de riesgo y el retraso de tratamientos tanto de fase aguda como de prevención secundaria. Se revisan los conceptos actuales sobre la enfermedad, así como los datos de estudios clínicos recientes y las estrategias de tratamiento.
