  1. Data are shown as mean (SD) or n (%) as appropriate, unless indicated otherwise
  2. VO2 Max is the maximal oxygen uptake in 1 min during maximal exhaustive exercise
  3. VE/VCO2 is the ventilatory equivalent for carbon dioxide (an indicator of ventilatory efficiency)
  4. V-POSSUM stands for the risk profile measured by the Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity
  5. ACEI = angiotensin converting enzyme inhibitor
