CARDIOPULMONARY
(1) The patients received health education on cardiac rehabilitation. (2) Cardiopulmonary function, health-related physical fitness, and risk factors were evaluated at the time of enrollment. (3) Individualized exercises for cardiac rehabilitation were prescribed based on the evaluation results: exercise 3–5 times a week, 30 min each time. Exercise methods: jogging or power cycling was used for exercise, low and medium intensity aerobic endurance exercise training, 3–5 times a week, 40 min each training, a total of 12 weeks. The specific methods were as follows: ① 5 min warm-up exercise. Mainly stretching gymnastics and walking. (2) 30 min aerobic training: (a) low intensity aerobic endurance training with target heart rate 40–60% of the maximum heart rate, subjective body sensation calculation RPE < 13 (mild), and 35–45% maximal oxygen uptake; (b) medium-intensity endurance training with the target heart rate 60–75% of the maximum heart rate, subjective body sensation calculation RPE 12–13 (medium), and 46–63% maximal oxygen uptake. ③ 5 min finishing exercise: patients could choose slow walking or relaxation gymnastics. (4) Return to the hospital at 4 and 12 weeks for follow-up evaluation and renewal of exercise prescriptions. The cardiac rehabilitation execution period was 12 weeks, during which 3 evaluations are completed, and at the time of enrollment (week 0), ± 7 days at week 4 and ± 7 days at week 12.
