Coronary vasospasm
Coronary Vasospasm
Coronary vasospasm (pronunciation: kuh-ROH-nuh-ree vay-spaz-uhm), also known as Prinzmetal's angina, is a condition characterized by the temporary narrowing or constriction of the coronary arteries, which supply blood to the heart.
Etymology
The term "coronary" is derived from the Latin word "corona", meaning crown, referring to the crown-like appearance of the coronary arteries surrounding the heart. "Vasospasm" is a combination of the Greek words "vaso", meaning vessel, and "spasm", meaning sudden contraction.
