Abstract: Objective: To explore the effects of cardiopulmonary exercise rehabilitation on cardiopulmonary function and quality of life in home-based elderly patients with coronary heart disease accompanied by frailty. Methods: The 98 patients in the community health service center of Hanghai east road in Zhengzhou city were divided into two groups according to their residence, the intervention group and the control group with 49 patients in each group. The control group received cardiopulmonary rehabilitation health education, while the intervention group received cardiopulmonary rehabilitation health education and cardiopulmonary exercise rehabilitation. The changes of cardiopulmonary function, frailty and quality of life in the two groups before and after intervention were compared. Results: After intervention, the heart rate, systolic blood pressure, diastolic blood pressure, and cardiac load of the intervention group were significantly improved compared with the control group, and the differences were statistically significant (P<0.05); The forced vital capacity, forced vital capacity in the first second, and the level of one second rate in the intervention group were significantly improved compared with the control group (P<0.05); The scores of frailty in the intervention group were obviously lower than those in the control group, the differences were statistically significant (P<0.05); The scores of total quality of life in the intervention group were obviously higher than those in the control group, the differences were statistically significant (P<0.05). Conclusion: Cardiopulmonary exercise rehabilitation can improve patients' cardiopulmonary function and improve their quality of life.
