Coronary vasospasm refers to when a coronary artery suddenly undergoes either complete or sub-total temporary occlusion. [1] In 1959, Prinzmetal et al. described a type of chest pain resulting from coronary vasospasm, referring to it as a variant form of classical angina pectoris. [2] Consequently, this angina has come to be reported and ...
a reduction of blood flow to the heart that can be caused by stenosis, spasm, or acute occlusion (by an embolus) of the heart's arteries. resistance of the blood vessels. This can be caused by narrowing of the blood vessels; a decrease in radius. [33] Blood flow is proportional to the radius of the artery to the fourth power.
Variant angina. Variant angina, also known as Prinzmetal angina, vasospastic angina, angina inversa, coronary vessel spasm, or coronary artery vasospasm, [2] is a syndrome typically consisting of angina (cardiac chest pain). Variant angina differs from stable angina in that it commonly occurs in individuals who are at rest or even asleep ...

Vasospasm refers to a condition in which an arterial spasm leads to vasoconstriction. This can lead to tissue ischemia (insufficient blood flow) and tissue death (necrosis). Cerebral vasospasm may arise in the context of subarachnoid hemorrhage. Symptomatic vasospasm or delayed cerebral ischemia is a major contributor to post-operative stroke ...
