Final answer:
Prinzmetal's angina is the term for vasospasms associated with chest pain.
Step-by-step explanation:
Vasospasms associated with chest pain are known as Prinzmetal's angina.
Angina is chest pain or pressure that occurs when heart muscle cells do not receive adequate blood flow and become starved of oxygen. Stable angina is angina in which pain is precipitated by exertion and improves quickly with rest or the administration of nitroglycerin, while unstable angina is angina in which pain occurs during rest, lasts more than 15 minutes, and is of new onset. Prinzmetal's angina is a variant of angina in which chest pain is caused by vasospasms of the coronary arteries, leading to reduced blood flow and oxygen supply to the heart.
