Design outcomes

Primary

Measure	Time frame
Categorical data: sex, euroSCORE, ASA-score, comorbidity, educational status, smoking status, number of grafts, number of complications. Echographic data: TTE and TOE strain and strain rate. Data will be described as mean and standard deviation.	—

Secondary

Measure	Time frame
Systolic myocardial function: Ejection fraction (2ch and 4ch), Fraction of shortening, Fraction of area change, Stroke volume, dP/dt, Mitral tissue doppler (systolic curve). Diastolic myocardial function: Mitral wave (E/A ratio, E wave, A wave), Pulmonary wave (S/D, S wave, D wave, A wave), Mitral tissue doppler (diastolic curves). NIRS: myocardial tissue oxygenation values.	—
