Interventions	Intervention: 1) Exercise mode: Walk or jog on the exercise board (T2100 exercise board equipped with 12 leads ECG and blood pressure monitoring) 2) Exercise intensity: The heart rate reserve method was used combining self‐perceived fatigue of the participant to reach 50% to 80% of the maximum exercise intensity or Borg rate of perceived exertion at 12 to 16 3) Exercise time: 30 ‐ 60 mins, including 5 ‐ 10 mins warm‐up and relaxation exercises 4) After discharge, participants can choose one or more kinds of aerobic exercise rehabilitation from walking, jogging, walking on the treadmill, cycling, swimming, and playing badminton etc. for 3 to 5 times a week.
