Angina acelerante; Angina de aparición reciente; Angina progresiva
Es una afección en la cual el corazón no recibe suficiente flujo de sangre y oxígeno y puede llevar a un ataque cardíaco.
La angina es un tipo de molestia en el pecho causada por el flujo deficiente de sangre a través de los vasos sanguíneos (vasos coronarios) del músculo cardíaco (miocardio).

La arteriopatía coronaria debido a ateroesclerosis es de lejos la causa más común de la angina inestable. La ateroesclerosis es la acumulación de material graso llamado placa a lo largo de las paredes de las arterias. Esto hace que dichas arterias se vuelvan menos flexibles y se estrechen, lo cual interrumpe el flujo sanguíneo al corazón, causando dolor torácico.
Las personas con angina inestable están en mayor riesgo de tener un ataque cardíaco.
Un espasmo de la arteria coronaria es una causa poco común de angina.
Los factores de riesgo para la arteriopatía coronaria comprenden:
