    Critically ill patients have raised troponins. This study aimed to assess the incidence of myocardial injury in the intensive care unit (ICU) at a tertiary care hospital and assess the management and prognosis. This retrospective study included adult patients who were admitted to the ICU of Sultan Qaboos University Hospital, Muscat, Oman, between January and December 2019 and had undergone a high-sensitive cardiac troponin (hs-cTn) assay. Patients admitted with a primary diagnosis of myocardial infarction were excluded. A total of 264 patients had their hs-cTn measured during the study period. Of these, 128 (64.3 ± 17.1 years; 58.6% male) had elevated levels, giving an incidence rate of approximately 48.5%. Those with raised troponin were older and had more co-morbidities. These patients were also more critically ill with lower blood pressure, higher heart rates and increased hypotensive episodes. Of these, 47 were treated for acute coronary syndrome, 32 underwent coronary angiography and only three required stenting. Patients with raised troponin had a poor outcome with only 45 (35.2%) surviving to discharge compared to 101 (74.3%) with normal troponin. Patients with raised troponin had shorter hospital stays than those with normal troponin (16 versus 19 days; P = 0.017). A high proportion of critically ill patients showed evidence of myocardial injury without significant coronary artery disease, which is associated with a poor prognosis. Further prospective studies are required to ascertain the best course of treatment for these patients. © Copyright 2022, Sultan Qaboos University Medical Journal, All Rights Reserved.
