Prognostic value of myocardial injury and chronic kidney disease in an emergency unit

Abstract Background Cardiac troponin is independently associated with cardiovascular events and mortality in patients with chronic kidney disease (CKD). Their joint effect is yet to be clarified. Purpose This study aims to evaluate the prognostic implication of myocardial injury and CKD in patients attended in an emergency room. Methods Retrospective study carried out between January 2012 and December 2013 with consecutive patients attended in an emergency room with troponin determination, who were distributed into four cohorts according to positive troponin and/or glomerular filtration rate (GFR)
