Variant angina differs from stable angina in that it commonly occurs in individuals who are at rest or even asleep, whereas stable angina is generally triggered by exertion or intense exercise. Variant angina is caused by vasospasm, a narrowing of the coronary arteries due to contraction of the heart's smooth muscle tissue in the vessel walls. [3]
Vasospasm is the major cause of Prinzmetal's angina. Cerebral vasospasm may arise in the context of subarachnoid hemorrhage as symptomatic vasospasm (or delayed cerebral ischemia), where it is a major contributor to post-operative stroke and mortality. Vasospasm typically appears 4 to 10 days after subarachnoid hemorrhage, however the ...
This discovery led to this type of angina being referred to in the literature as Prinzmetal angina. [ 3 ] [ 20 ] A following study further distinguished this angina from classical angina pectoris due to the fact that the results showed that the patients with chest pain due to coronary vasospasm lacked evidence of atherosclerosis on cardiac ...

There are many conditions of or affecting the human circulatory system — the biological system that includes the pumping and channeling of blood to and from the body and lungs with heart, blood and blood vessels.

Angina, also known as angina pectoris, is chest pain or pressure, usually caused by insufficient blood flow to the heart muscle (myocardium). [2] It is most commonly a symptom of coronary artery disease. [2] Angina is typically the result of partial obstruction or spasm of the arteries that supply blood to the heart muscle. [3]
[5] [6] [14] It is the most common of the cardiovascular diseases. [15] CAD can cause stable angina, unstable angina, myocardial ischemia, [16] and myocardial infarction. [17] A common symptom is angina, which is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. [4] Occasionally it may feel like heartburn.
