Abstract
Unstable angina is a high risk syndrome which may be defined by the new onset of angina symptoms, a crescendo pattern of angina, and the occurrence of rest angina. The pathophysiology of this condition is complex, and involves a combination of fixed coronary atherosclerosis and superimposed dynamic coronary obstruction, mediated by coronary vasoconstriction, and/or platelet aggregation and thrombosis (1,2). Although aggressive medical therapy for patients with unstable angina often successfully controls symptoms in the coronary care unit, a significant proportion of patients whose symptoms are initially ameliorated nevertheless experience cardiac death, myocardial infarction, and recurrent angina requiring revascularization (3–6).
