Retrospective Analysis of Hospitalizations in the Cardiac Intensive Care Unit

This retrospective study analyzes 670 hospitalizations in the Cardiac Intensive Care Unit (CICU) at Joseph Imbert Hospital Center in Arles, France, between December 2022 and December 2023. The objective was to evaluate patient profiles, reasons for admission, length of stay, and outcomes, including mortality and readmission. The most common causes of admission were Acute Coronary Syndrome (ACS, 28%) and supraventricular tachycardia (17%). The median age was 73.4 years, and 60% of admissions were male. The in-hospital mortality rate was 4.18%, increasing with age, and reached 90% in patients with cardiogenic shock. Non-cardiac causes such as pneumonia and COPD accounted for 32% of in-hospital deaths. Hemodynamic and respiratory failures were the most fatal during hospitalization. The study highlights the need for improved triage and orientation of patients with respiratory pathologies and better post-discharge monitoring, especially for those with heart failure.
