Importance and Application of Exercise Rehabilitation after PCI in Elderly Patients with Coronary Heart Disease

Focusing on exercise rehabilitation for elderly patients with coronary artery disease after coronary angiography, this paper systematically analyzes the multifaceted significance of exercise rehabilitation in restoring physical function, improving mental health, and enhancing quality of life. The paper explores the mechanisms and clinical effects of rehabilitation modalities, including aerobic exercise to promote collateral circulation and cardiac function, resistance training to improve lipid profile by increasing muscle mass, flexibility training to prevent joint stiffness, and balance training to reduce the risk of falls. Key findings emphasize that exercise rehabilitation can promote the aerobic metabolism of myocardium, increase myocardial oxygen uptake, enhance myocardial contractility, improve cardiac pumping function, improve cardiac function, significantly reduce cardiovascular events and postoperative complications, and improve patients' quality of life. Meanwhile, early exercise rehabilitation has a positive impact on patients' psychological state through neurobiological mechanisms, improves psychological comfort, reduces anxiety and depression, and improves the negative psychological state of patients after coronary heart disease surgery. The study provides both theoretical frameworks and practical guidance for integrating scientific exercise programs into post-PCI rehabilitation, emphasizing its role in achieving comprehensive physical and psychological recovery for elderly patients.
