Abstract: Background/aim: The aim of this study was to determine the patient profile, treatment, and outcomes of a coronary care unit (CCU) by retrospective screening of 12-year patient records. Materials and methods: The data of 13,463 patients admitted to the CCU of a tertiary referral hospital between 1 January 1997 and 30 June 2008 were collected. The patients were assessed with respect to demographics, admission diagnosis, treatment, and outcomes. Results: The mean age of patients was 61 ± 13 years (66.7%, male). While the diagnosis of acute coronary syndrome (ACS) accounted for 65%, the rate of ST elevation myocardial infarction (STEMI) was 43.4%. Thrombolytic therapy was administered to 48.7% of the patients with STEMI. Systolic heart failure was the most frequent disease (11.9%) among the non-ACS diagnoses. The mortality rate of the CCU was 12.7% on average; it increased gradually after 2005 when the CCU became a general intensive care unit. Conclusion: This study is one of the largest comprehensive analyses of patient profile and outcomes of a CCU. Despite advances in the diagnosis and treatment of cardiac emergencies, the mortality rate of the CCU was high. Serving as a general intensive care unit, the absence of a coronary angiography laboratory and lower use of thrombolytic therapy for STEMI might be responsible factors.
