| Prinzmetal's a. |
a variant of angina pectoris, often considered a form of unstable angina, in which the attacks occur during rest, exercise capacity is often well preserved, and attacks are associated electrocardiographically with elevation of the ST segment. Focal spasm of an epicardial coronary artery causes transient abrupt reduction of arterial diameter, resulting in myocardial ischemia. Called also variant a. pectoris and vasospastic a.
