Les patients hospitalisés en réanimation pour un syndrome coronarien aigu de 2012 à 2021 : une étude rétrospective monocentrique

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.
