The pathophysiology of unstable<unk>  is controversial. Until recently, unstable<unk>  was assumed to be<unk>  pectoris caused by disruption of an atherosclerotic plaque with partial thrombosis and possibly embolization or vasospasm leading to myocardial ischemia. However, sensitive troponin assays reveal rise of cardiac troponin in the bloodstream with episodes of even mild myocardial ischemia. Since unstable<unk>  is assumed to occur in the setting of acute myocardial ischemia without troponin release, the concept of unstable<unk>  is being questioned with some calling for retiring the term altogether.
