It is a clinical syndrome within cardiology and emergency medicine that presents as episodic chest discomfort from myocardial ischemia. It is most commonly discussed in the context of electrocardiography (ECG) changes during symptoms and evaluation for acute coronary syndrome (ACS). It is also known as vasospastic angina and is historically associated with the term Prinzmetal angina."}
