La revista ECA: Estudios Centroamericanos, fundada en 1946 por la Compañía de Jesús y vinculada desde 1965 a la Universidad Cetroamericana José Simeón Cañas (UCA), constituye una de las publicaciones académicas de mayor continuidad y densidad intelectual en la historia reciente de Centroamérica y El Salvador.

Este artículo propone una aproximación interdisciplinaria a su trayectoria, articulada en dos líneas complementarias: una histórica, que reconstruye el origen, la evolución editorial y el sentido crítico de la revista en el contexto salvadoreño y centroamericano; y otra bibliométrica, que examina su producción, impacto citacional, presencia autoral y comportamiento editorial a lo largo del tiempo. A partir de este análisis descriptivo, se busca demostrar, mediante el método bibliométrico, que la voz de autores como los padres jesuitas y autores vinculados a la tradición de los mártires de la UCA continúa teniendo incidencia, vigencia e impacto dentro del debate académico contemporáneo.

En ese sentido, el análisis no solo examina su presencia autoral en la producción científica, sino también la persistencia de su pensamiento en la comprensión de la realidad social centroamericana y en la construcción de una reflexión crítica comprometida con la transformación social.
