Tomografía computarizada del corazón - Results

Nombres alternativos

TAC del corazón; Tomografía axial computarizada del corazón; TAC cardíaco; Cuantificación del calcio; Tomografía computarizada del corazón con multidetectores; Tomografía computarizada del corazón por haz de electrones; Puntuación de Agatston; Gammagrafía de calcio coronario

Valores normales:

Los resultados se consideran normales si el corazón y las arterias examinadas son normales en apariencia.

El médico puede usar los resultados de este examen para determinar su "puntaje de calcio". Dicho puntaje se basa en la cantidad de calcio encontrado en las arterias del corazón.

El examen es normal (negativo) si su puntaje de calcio es 0. Esto significa que la posibilidad de tener un ataque cardíaco durante los próximos dos a cinco años es muy baja. Si el puntaje del calcio es muy bajo, es improbable que usted tenga arteriopatía coronaria.

Significado de los resultados anormales:

Los resultados anormales pueden deberse a:

  • Aneurisma.
  • Cardiopatía congénita.
  • Arteriopatía coronaria.
  • Problemas de válvulas cardíacas.
  • Inflamación de la cubierta alrededor del corazón (pericarditis).
  • Estrechamiento de una o más arterias coronarias (estenosis de arterias coronarias).
  • Tumores del corazón o áreas circundantes.

Su médico también puede darle un "puntaje del calcio" después de este examen. Si dicho puntaje es alto, eso significa que usted tiene acumulación de este elemento en las paredes de las arterias coronarias, lo cual es un signo de ateroesclerosis o endurecimiento de dichas arterias. Cuanto más alto sea su puntaje, más grave puede ser esta afección. Hable con su médico respecto a los resultados de su tomografía computarizada del corazón y de su puntaje del calcio.
