Aggressive versus conservative therapy in unstable angina

In patients with unstable angina, non-Q-wave, and Q-wave myocardial infarction, atherosclerotic plaque rupture leads to a variable amount of platelet adhesion and aggregation, vasoconstriction, and partially or totally occlusive thrombus formation. This article focuses on the role of aggressive (routine angiography and revascularization) versus conservative (maximal medical therapy, with catheterization and revascularization reserved for those with spontaneous or provable ischemia) management of the patient with unstable angina.
