Short term morbidity after elective cardiac surgery remains significant. Standard predictive models, considering simple patient demographics and clinical parameters, show limited efficiency in individual operative risk assessment. There is growing evidence about daily physical activity as a relevant indicator of preoperative "frailty". Although cardiopulmonary exercise testing remains a gold standard, we are looking for more simple tools in order to identify patients with poor physical condition. Accelerometry may be an objective and reproductible method to measure physical activity at patient's home.
The aim of this study is to compare accelerometer-assessed preoperative physical activity between two groups of patients with different postoperative length of stay following elective cardiac surgery. In the future, accelerometry could be used to identify patients that may benefit from prehabilitation programs including exercise therapy before elective cardiac surgery.

Analysis of questionary Duke Activity Status Index (DASI) over a period of 7 days
Questionary Duke Activity Status Index (DASI) estimates the maximum volume of oxygen used in one minute (VO2 Max) as well as its effort capacity in metabolic equivalent. It contains 11 items. The higher the score indicates better functional capacity.
Time frame: Day: 7
Analysis of questionary Short Nutritional Assessment Questionnaire (SNAQ) over a period of 7 days
Questionary Short Nutritional Assessment Questionnaire (SNAQ) evaluates nutritional status. The higher the score indicates an important nutritional support.
Time frame: Day: 7

Measured by blood sample.
Time frame: Day: 7
Dosage of prealbumin (g/L)
Measured by blood sample.
Time frame: Day: 7

Measured by Hand Grip test.
Time frame: Day: 14
