In-Hospital Mortality in Cardiac Surgery Patients After Readmission to the Intensive Care Unit: A Single-Center Experience with 10,992 Patients

Patient readmission to the ICU following cardiac surgery was associated with a 5-fold increase in hospital mortality rate compared to non-readmitted patients. The highest mortality rate was observed among readmitted patients who underwent CABG. Older age, previous myocardial infarction, and initial long length of stay in the post-operative ward were independent risk factors for death after readmission to the ICU.
