<unk>  is a multi-factorial, transient, and abrupt reduction of luminal diameter of an epicardial coronary artery due to inappropriate constriction of coronary smooth muscle that can generate distal ischemia.  This may occur spontaneously or in the context of angioplasty, particularly if denudation of the endothelium or dissection occurs.  In addition, the<unk>  can either be focal or multifocal (which compromises more than one vessel).
