Espasmo de las arterias coronarias - Symptom

Nombres alternativos

Angina variante; Angina de Prinzmetal; Angina vasoespástica

Síntomas:

Los espasmos pueden ser silenciosos (sin síntomas) o pueden ocasionar dolor torácico o angina. Si el espasmo dura mucho tiempo, puede incluso causar un ataque cardíaco.

El síntoma principal es un tipo de dolor torácico llamado angina, el cual se puede sentir debajo del esternón y se puede describir como:

  • Opresivo
  • Aplastante
  • Presión
  • Compresión
  • Tensión

Generalmente es severo y puede irradiarse al cuello, la mandíbula, el hombro o el brazo.

El dolor:

  • Suele ocurrir en reposo
  • Puede ocurrir a la misma hora cada día, generalmente entre la medianoche y las 8:00 a.m.
  • Dura de 5 a 30 minutos

La persona puede perder el conocimiento.
