deinonychus commented on the word coronary steal
Coronary steal (with its symptoms termed 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. (Wikipedia)
