Factors relating with exercise duration of phase I cardiac rehabilitation for patients after percutaneous coronary intervention
摘要
Objective To investigate the current status of exercise duration of phase I cardiac rehabilitation for patients after percutaneous coronary intervention (PCI), and analyze its related factors. Methods A total of 120 patients who underwent PCI and participated in phase I cardiac rehabilitation from May, 2022 to May, 2024 were reviewed. Their clinical data were collected using a self-designed questionnaire, and the exercises duration of cardiac rehabilitation was recorded. Results The average daily exercise duration of cardiac rehabilitation was (19.45±6.32) minutes. The scores of fatigue, family support and exercise fear were (62.55±4.37), (84.87±10.65) and (41.98±5.24), respectively. There were significant differences in the exercise duration of rehabilitation among patients with different ages, body mass, cardiac function grades, presence or absence of postoperative angina pectoris, and presence or absence of postoperative nutritional intervention (P＜0.05). Pearson's correlation analysis showed that the exercise duration of rehabilitation correlated with the scores of fatigue (r=-0.247, P＜0.05), exercise fear (r=-0.235, P＜0.05) and family support (r=0.206, P＜0.05). Multiple linear regression analysis revealed that postoperative angina pectoris (B=-3.210, 95%CI -5.564 to -0.855), postoperative nutritional intervention (B=-3.738, 95%CI -6.790 to-0.686), fatigue (B=-0.182, 95%CI -0.349 to -0.014), family support (B=0.086, 95%CI 0.003 to 0.169) and exercise fear (B=-0.139, 95%CI -0.248 to -0.030) were independent factors relating to the duration of rehabilitation exercise (P＜0.05). Structural equation modeling showed that there were direct effects of all the five independent factors on the exercise duration of rehabilitation, while indirect effects were found in postoperative angina pectoris and postoperative nutritional intervention. Conclusion It is needed to improve the exercise duration of phase I cardiac rehabilitation for patients after PCI. Postoperative angina
