Coronary steal is also the mechanism in most drug-based cardiac stress tests; When a patient is incapable of doing physical activity they are given a vasodilator that produces a "cardiac steal syndrome" as a diagnostic procedure.
Pharmacologic stress testing relies on coronary steal.

Arteriolar vasodilator

Arteriolar vasodilator
When used on people with certain heart conditions, it causes a phenomenon known as the cardiac steal syndrome.

Coronary arteries

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.

Ischemia

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.

Sodium nitroprusside

It has been associated with nitroprusside.

Clevidipine

No increase in myocardial lactate production in coronary sinus blood has been seen, confirming the absence of myocardial ischemia due to coronary steal.

Teratoma

In the case of large sacrococcygeal teratomas, a significant portion of the fetus' blood flow is redirected toward the teratoma (a phenomenon called steal syndrome), causing heart failure, or hydrops, of the fetus.

Redistribution indicates the existence of coronary steal and the presence of ischemic coronary artery disease.

This produces coronary steal by areas where arteries are maximally dilated.

Within the contexts of nephrology and dialysis, vascular access steal syndrome is also less precisely just called steal syndrome (for short), but in wider contexts that term is ambiguous because it can refer to other steal syndromes, such as subclavian steal syndrome or coronary steal syndrome.
