Cardiac rehabilitation
The exercise training prescription adopted the FITT (frequency, intensity, time duration, and type of exercise) model. The following procedures were used in hospital-based CR and remote CR: (1) preparatory exercises, (2) using a bicycle ergometer or treadmill walking, (3) resistance training of the upper and lower extremities, and (4) organisational exercises. In addition, the exercise frequency was twice weekly, and the intensity of the bicycle ergometer was 40–60% of aerobic VT or PeakVO
