Coronary steal (with its symptoms termed coronary steal syndrome or cardiac steal syndrome) is a phenomenon where an alteration of circulation patterns lead to a reduction in the blood directed to the coronary circulation. It is caused when there is narrowing of the coronary arteries and a coronary vasodilator is used – "stealing" blood away from those parts of the heart. This happens as a result of the narrowed coronary arteries being always maximally dilated to compensate for the decreased upstream blood supply. Thus, dilating the resistance vessels in the coronary circulation causes blood to be shunted away from the coronary vessels supplying the ischemic zones, creating more ischemia.

  • El término robo coronario (que, junto con los síntomas, se denomina también síndrome de robo cardiaco) define a un fenómeno en el que una alteración de los patrones de circulación conlleva a una reducción en el flujo de sangre dirigida a la circulación coronaria del corazón. Se produce cuando existe un estrechamiento de las arterias coronarias y, al administrar un medicamento vasodilatador, las zonas que no sufrieron el estrechamiento inicial logran dilatarse en mayor proporción que las arterias afectadas, "robando" la sangre desde las partes estrechas del corazón. Por lo tanto, la dilatación de los vasos sanguíneos en la circulación coronaria hace que la sangre se desvíe de los vasos coronarios que suministran las zonas isquémicas, creando más isquemia.
