The hypothesis is that the preoperative Clinical Frailty Score (CFS) is a predictive factor for a loss in quality-adjusted life years (QALYs) one year after emergency cardiac surgery under cardiopulmonary bypass (CPB) in patients aged 75 years and older.
Immediate emergency surgery: intervention performed before the start of the next working day following the decision to operate,
Urgent (relative) emergency surgery: patients not admitted electively for surgery but requiring an intervention during the current hospital stay for medical reasons, and who cannot be discharged without undergoing a definitive procedure
Patients requiring preoperative cardiopulmonary resuscitation
Scheduled (elective) surgery
Lack of informed consent
Impaired consciousness at the time of inclusion (defined by a Glasgow Coma Scale score < 15)
