چکیده

Resumen Objetivo: El propósito del estudio era investigar si la hipoalbuminemia y otros factores de riesgo de mortalidad tras un ictus tenían el mismo valor pronóstico tras un ictus a corto (1 mes), medio (3 meses), largo (1 año) o muy largo plazo (5 años). Métodos: Se estudiaron 254 pacientes ingresados en nuestro hospital con ictus isquémico y seguidos prospecti-vamente durante dos años con un procolo estándar de forma prospectiva. Se recogieron datos adicionales hasta 5 años de las Historias Clínicas, los datos del laboratorio, un cuestionario enviado por correo, una llamada telefó-nica y la revisión de los Registros de Mortalidad de los ayuntamientos. Los factores de riesgo de mortalidad en cada periodo se calcularon con regresión logistica y el modelo de riesgos proporcionales de Cox. Resultados: Se asociaron de forma significativa con la mortalidad al mes el mecanismo cardioembólico, la hipo-albuminemia, la glucemia al ingreso, la edad, la presión arterial diastólica más baja y la puntuación en la Escala Canadiense. A los tres meses, la existencia de ictus previos y el índice de Barthel al alta. Al año la existencia previa de demencia y el índice de Barthel a los 3 meses y a los cinco años la edad, la puntuación en la escala Canadiense al alta y un colesterol menor al ingreso. El análisis de regresión de Cox considerando el tiempo de supervivencia, mostró una asociación independiente con la mortalidad de la hipoalbuminemia al ingreso ((HR) 2; p = 0,03), la edad (HR 1,06; p < 0,00), la demencia previa (HR 2; p < 0,00), el mecanismo cardioembólico (HR 2; p < 0,00) y la severi-dad según la escala Canadiense (HR 1.2; p < 0,00). Conclusión: La mortalidad tras un ictus isquémico parece depender de distintos factores según el tiempo transcurrido. Abstract Objective: The aim of this study was to investigate whether hypoalbuminemia and other risk factors for mortality after stroke have the same or different short (1 month), medium (3 months), long (1 year) or very long term (5 years) prognostic value. Subjects/methods: clinical and analytical data from 254 patients admitted to our Hospital with an ischemic stroke and followed up prospectively for 2 years were collected with a prospective standard protocol. Additional data up to 5 years were obtained from Clinical and Laboratory Registries of the Hospital, a mailed questionnaire, a phone call and the Council Registry of Mortality. Risk factors for mortality at different time …
