Phase angle determined by bioelectrical impedance analysis is a strong prognostic factor in several medical areas as clinical nutrition, nephrology, infectious disease, oncology. Inflammation, frailty status and fluid overload can lead to a phase angle decreased. Some studies support its use for risk stratification in intensive care unit and other in preoperative for cardiac surgery. The investigators would like to evaluate its relevance for risk stratification at intensive care unit admission in the context of postoperative cardiac surgery with cardiopulmonary bypass.
Study Type
OBSERVATIONAL
Enrollment
220
Segmental multi-frequency bioelectrical impedance analysis are carried out at all patient admitted to our ICU for postoperative care after cardiac surgery with cardiopulmonary bypass. Our objective is to evaluate the relevance of phase angle to predict mortality or a prolonged hospital length of stay. Phase angle is evaluated at ICU admission and will be compared to well-known prognostic scores computed in preoperative (EuroSCORE II) and at day one after surgery (SOFA, CASUS and SAPS II).

Area under the receiver operating characteristic curve to predict a composite criterion including in-hospital mortality or prolonged hospital length of stay.
The phase angle's area under the receptor operative curve to predict a composite criteria evaluated at hospital discharge and combining: * In hospital mortality * Prolonged hospital length of stay, defined by an in hospital length of stay greater than the 75th percentile of length of stay in the study population"
Time frame: at 6 months after the cardiac surgery
