Background: Remote ischaemic preconditioning (RIPC) induced by brief ischaemia and reperfusion of the arm reduces myocardial injury in coronary artery bypass (CABG) surgery patients receiving predominantly crossclamp fibrillation for myocardial protection. However, coldblood cardioplegia is the more commonly used method world wide. Objective: To assess whether RIPC is cardioprotective in CABG patients receiving cold-blood cardioplegia.

DMF as measured by EQ-CMR is elevated in severe AS vs. normal controls but with a considerable overlap. It correlates with functional capacity at baseline. LV hypertrophy regression 6 months after AVR is cellular rather than fibrosis resolution.
