Coronary Vasospasm is a medical condition where the walls of the arteries in the heart unexpectedly contract, leading to reduced blood flow to the heart muscle. This condition is also known as Prinzmetal's angina or variant angina. Apart from these, there are some other synonyms that are used to refer to this condition, such as coronary artery spasm, coronary artery constriction, coronary artery narrowing, and spastic angina. The symptoms of coronary vasospasm include chest pain, shortness of breath, and sweating. It is important to seek medical attention if you experience any of these symptoms as coronary vasospasm can lead to serious heart problems such as heart attack or irregular heartbeat.
