La isquemia miocárdica es un fenómeno plurifactorial que produce un cambio hacia el metabolismo anaerobio en la célula muscular. Los cambios inducidos pueden ser reversibles en un primer momento antes de llegar al daño irreversible con muerte celular. El aumento en el aporte de oxígeno o la reducción de los requerimientos energéticos del miocardio protegen de la isquemia miocárdica. Desde el punto de vista fisiopatológico, el control y la reducción de la frecuencia cardiaca añadidos al restablecimiento del flujo coronario pueden ser la piedra angular en el tratamiento de esta afección.
