RESUMEN

Introducción: La enfermedad aterosclerótica coronaria es causa importante de muerte en Cuba y el resto del mundo. El volumen de grasa epicárdica se considera un nuevo factor de riesgo cardiovascular por su asociación con la aterogénesis coronaria.
Objetivo: Determinar, mediante tomografía computarizada multicorte, la asociación entre el volumen de grasa epicárdica y la presencia de placas ateroscleróticas coronarias.
Método: Se desarrolló un estudio descriptivo, con un universo de 130 pacientes con dolor torácico sugestivo de cardiopatía isquémica, de donde seleccionaron 117 por muestreo opinático. Se les realizó calcio score, angiotomografía coronaria y medición del volumen de grasa epicárdica.
Resultados: Predominaron los hombres (54,7 %) y las edades comprendidas entre 60- 69 años (32,5 %). El 51,3 % de los pacientes tuvo un volumen de grasa epicárdica elevado, situación que afectó al 52,8 % de las mujeres. El 78,9 % de los pacientes con calcio score entre 100-399 UH tenían un volumen de grasa epicárdico elevado; al igual que el 71,2 % de los que tenían placas de ateroma y el 100 % de los que tenían un nú- mero de 4 o 5 placas. El 41 % de los pacientes tenían varios tipos de placa, las que se localizaron mayoritariamente en la arteria descendente anterior (88,1 %).
Conclusiones: La medición del volumen de grasa epicárdica es una herramienta útil para estimar la presencia de enfermedad coronaria. Cuando estuvo elevado, se asoció a la mayor edad, al sexo femenino y a la presencia de mayor calcio score, más placas de ateroma, mayor número de lesiones y más afectación de la arteria descendente anterior.
