In patients with acute myocardial infarction, the protection of the myocardium was often overemphasized in the past, and patients were advocated to stay in bed for 6 weeks to await myocardial scar formation. However, prolonged bed rest itself can lead to a decrease in blood volume and an increase in blood viscosity, which aggravates the already impaired cardiovascular dysfunction and at the same time leads to an increase in physical exercise capacity impairment. Therefore, there are many conditions and traumas that can be treated acutely and then rehabilitated within a month to actively prevent and reduce complications. Rehabilitation is a systematic “project” and is completely different from simple home exercises. Rehabilitation is a teamwork medical system, which usually consists of a rehabilitation physician to assess the patient’s functions, and a physical therapist and an occupational therapist to conduct exercise training and functional training (most of these are active treatments in which the patient actively participates), together with passive stimulation such as acupuncture and massage to enhance the treatment and the sound, light, electricity, heat and wave effects of physical therapy to maximize the rehabilitation effect.
