Effect of Individualized Exercise in Elderly Patients With Coronary Heart Disease

Effect of Individualized Exercise Based on CPET on Multiple Cardiovascular Risk Factors and Cardiopulmonary Function in Elderly Patients With Coronary Heart Disease

The benefits of cardiac rehabilitation have been supported by a large amount of evidence-based medicine. Cardiac rehabilitation can correct cardiovascular risk factors, reduce morbidity and mortality, and improve quality of life.

Cardiac rehabilitation includes drug, exercise, nutrition, psychological and behavioral intervention, smoking and alcohol restriction five prescription comprehensive medical measures, so as to improve the symptoms and prognosis of patients. Cardiac rehabilitation can not only delay the progress of the disease and improve the prognosis, but also improve the physical and mental state of patients, which has been recommended by the European Cardiology Association, the American Heart Association and the American Heart Association as Class I in the treatment of cardiovascular disease. Through the comprehensive intervention of patients, their physical, psychological and social functions can be restored to the best state, which can prolong life and significantly improve the quality of life, which is the essence of modern cardiac rehabilitation. Exercise rehabilitation is the core content of cardiac rehabilitation, which refers to the use of appropriate body exercise to help patients promote physical and mental health through exercise prescription and exercise guidance on the basis of comprehensive evaluation. The realization of sports rehabilitation requires a reasonable exercise prescription, which refers to the method of prescribing patients' exercise content and amount of exercise in the form of prescription according to individual physical condition and combining with environment and preference as far as possible. The best exercise prescription should be able to comprehensively promote health-related physical fitness, that is, cardiopulmonary endurance, muscle strength and endurance, flexibility, body composition and neuromotor fitness, and should be formulated in accordance with the principles of FITTVP, including frequency (several times a week), intensity (exertion), time (duration or total time), mode (pattern or type), as well as total and progress.
