Inclusion criteria
Inclusion criteria: Participants must meet all of the following criteria to be eligible for inclusion:Age: =18 years.Surgical procedure: Scheduled to undergo elective CABG or AVR via median sternotomy; Allowed concomitant procedures: Isolated procedures or in combination with concomitant procedures (i.e., MAZE, Pulmonary Vein Isolation (PVI), clip Left Arterial Appendage (LAA)).High-risk classification: Participants are classified as high-risk for postoperative in-hospital complications or delayed functional recovery during hospitalization using a predefined two-stage screening process.Stage 1: Elevated surgical risk Patients are initially screened based on surgical risk, defined as a EuroSCORE II = 1.33.Stage 2: Multivariable confirmation Patients meeting Stage 1 criteria undergo further risk stratification using internally developed and validated multivariable prediction models. These models integrate surgical risk and modifiable physical risk factors, including:EuroSCORE II (ESII); cardiorespiratory fitness (FitMáx); frailty (Edmonton Frail Scale, EFS); body mass index (BMI). Following logistic regression model is applied:Prediction of delayed postoperative recovery of physical functioning: Phigh risk=<img src="data:image/png;base64,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
