The diagnostic challenge of myocardial infarction in critically ill patients: Do high-sensitivity troponin measurements add more clarity or more confusion?

Abstract

In ICU settings, the diagnosis and treatment of acute myocardial infarction (AMI) are challenging, partly because cardiac troponin increase occurs frequently. In the previous issue of Critical Care, Ostermann and colleagues reported that myocardial infarction (MI), screened by plasma troponin and electrocardiography changes, is common and often clinically unrecognized in the ICU. Although the clinical significance of underdiagnosed MIs remains unclear, this approach may help to target and further investigate the at-risk population for appropriate therapy. © 2014 Klouche et al.; licensee BioMed Central Ltd.
