Changes of peak VO2
 Initial peak VO2 11.9 10.1 -
 Final peak VO2 15.0 12.6 8.1
 Term between CPX 12 weeks 2 years -
Changes of METs
 Initial METs 3.4 2.9 -
 Final METs 4.3 3.6 2.3
CR: cardiac rehabilitation, wk: week, RPE: rate of perceived exertion, RPM: revolutions per minute, peak VO2: peak oxygen uptake during cardiopulmonary exercise test, CPX: cardiopulmonary exercise test, METs: metabolic equivalents, The unit of VO2 is mL/kg/min, 1 MET is equivalent to 3.5 ml/kg/min
