Parametric data presented as mean ± SD; non-parametric data as median (25th–75th IQR).
AVR: aortic valve replacement; CABG: coronary artery bypass graft operation; CVA: cerebrovascular accident; IABP: intra-aortic balloon pump; TIA: transient ischaemic attack; MACCE: major adverse cardiac and cerebrovascular events; LGE: late gadolinium enhancement.
