ABSTRACT
INTRODUCTION: Acute Coronary Syndrome (ACS) are one of the main causes of mortality in France. Patients presenting with ACS are typically hospitalized in a specialized cardiology ward. The main objective of this study was to describe, characterize and evaluate the outcome of patients hospitalized for ACS in a generalist intensive care unit (rather than a cardiac care unit). METHODS: This was a retrospective study. Our population consisted of ACS patients admitted to an intensive care unit in a hospital center (Centre Hospitalier de Troyes) between 2012 and 2021. All patients admitted for ACS to the intensive care unit and who underwent coronary angiography were included. RESULTS: In 10 years, 104 patients, or 3.8% of ACS patients who underwent coronary angiography were admitted to intensive care. The majority were admitted after recovered cardiac arrest (72%) and were in cardiogenic shock (68%), accounting for a high in-hospital mortality (45.2%). In-hospital mortality was 45.2%. In multivariate analysis, the GRACE score was associated with in-hospital mortality (OR for each additional point = 1.024, 95% confidence interval 1.006-1.045, p = 0.01). Among the survivors, 88% had good neurological function when leaving the hospital. DISCUSSION: Mortality of ACS patients in intensive care was close to 50%. However, the neurological prognosis of the surviving patients was good. This population is rarely mentioned in the literature, and deserves to be evaluated by multicenter, prospective registries, with a view to improving management and prognosis.
