No evidence of cardiac stunning or decoupling immediately after cardiopulmonary bypass for elective coronary surgery

Background There is significant uncertainty regarding the timing of onset of cardiovascular stunning after cardiac surgery. Cardiovascular stunning is affecting both contractility (Ees) and arterial load. Arterial load may be represented by arterial elastance (Ea) and participates in ventriculo‐arterial coupling through the Ea/Ees ratio, giving information on efficiency and performance. An alternative approach to ventriculo‐arterial interaction...
