Increased C-reactive Protein Concentrations in Patients Admitted to the Emergency Department With Troponin Level Elevations Aids to Rule Out Coronary Ischemia

The investigators hypothesized that the CRP/troponin ratio measured in patients presenting to the ED with elevated troponin levels could differentiate between patients with cardiac ischemia and those who present due to a systemic inflammatory or infectious disease. The aim of the study was to determine the necessary CRP/troponin ratio required to rule out cardiac ischemia in a large ED population and determine its impact on long-term prognosis.
