Serum troponin elevation above the 99th percentile of the upper reference limit in healthy subjects (<0.01 ng/ml measured using currently available high.sensitivity cardiac troponin laboratory assays) is required to establish the diagnosis the diagnosis of myocardial necrosis in acute cardiovascular syndromes, as well as guide prognosis and therapy. In the perioperative period, for patients with cardiac disease undergoing noncardiac surgery, it is a particularly critical biomarker universally used to assess the myocardial damage. The value of troponin testing and elevation (as well as its significance) in patients with chronic cardiac valvular, vascular, and renal disease is relatively less well understood. This evidence.based review seeks to examine the currently available data assessing the significance of troponin elevation in certain chronic valvular and other disease states.
