Dr. Eugene Braunwald in 1989 proposed a classification system for unstable angina based on severity and clinical circumstances. This classification system was employed in various clinical trials and studies to determine its prognostic importance and clinical usefulness. In the recent years with more detailed understanding of the pathophysiology of unstable angina and the discovery of improved markers of myocardial injury, acute phase proteins and hemostatic markers, especially cardiac troponin I and troponin T, it was suggested to extend Class IIIB (angina at rest within the past 48 hrs) of the original classification, by subclassifying it into troponin negative and troponin positive patients.
