In the past, people thought that heart disease treatment was limited to passive injections and medication, and at most they underwent heart surgery and stent treatment, and they wrongly believed that these heart disease patients could only recuperate at home in bed every day, so that they could not do any exercise anymore, that is, heart disease all need “recuperation”, and some heart disease patients who want to exercise are also very worried about “moving”. Some heart patients who want to exercise are very worried about “moving out”. Some people who have just recovered from a heart attack, or who have just had heart surgery, or who have been diagnosed with heart failure, may be discouraged to think that they can only recuperate and have little hope of resuming their work and life as before. It is because of these misconceptions about the treatment of heart disease that many heart patients have a reduced or even lost workforce and a significantly lower quality of life than before the onset of the disease. The number of people who are repeatedly hospitalized or even die due to serious cardiovascular events such as myocardial infarction and heart failure is relatively high, and the resulting medical expenses are huge and burdensome. At present, the treatment of heart disease is not only the treatment of the disease itself, but also should include the prevention of heart disease and the rehabilitation of heart disease; especially after the occurrence of heart disease such as myocardial infarction, rehabilitation training and clinical drug therapy are two complementary and indispensable treatment links, appropriate drug therapy can relatively enhance the exercise ability of patients and improve the level and effect of training. The beneficial effects of exercise training also help to gradually reduce the amount of medication, and in some cases, patients can even stop some of their medication. Some data show that patients who undergo cardiac rehabilitation are able to reduce overall mortality by 27% and coronary heart disease mortality by 31% compared to patients who do not receive rehabilitation. Moreover, cardiac rehabilitation activities significantly improve patients’ symptoms, reduce fatigue, reduce angina attacks, patients are less anxious and depressed, physical activity capacity is increased, and patients’ subjective perceived quality of life is significantly improved. Cardiac rehabilitation can significantly shorten the number of hospital days, reduce the rate of re-hospitalization, and reduce medical costs. That is why it is said, “Cardiac rehabilitation is the treatment of choice for the physical and mental health of heart patients.” Patients can benefit from cardiac rehabilitation whether they have coronary artery disease, angina, myocardial infarction or heart failure, cardiomyopathy, or have undergone cardiac surgery or other treatments such as coronary artery bypass, coronary balloon dilation, stent implantation or valve replacement surgery. Cardiac rehabilitation is an exercise based non-pharmacological treatment added to the correct diagnosis of heart disease and conventional medication and surgical treatment. Cardiac rehabilitation is not a fitness exercise, but a comprehensive and long-term treatment process, and a gradual process, including cardiopulmonary function assessment, supervised functional recovery training (i.e., the doctor will give the patient a personalized exercise program according to the patient’s condition and the patient’s cardiopulmonary function and other different conditions, and make flexible adjustments according to the patient’s recovery situation. The exercise here is not as simple as moving the legs and hands, but a special “exercise prescription”, which is very specific in terms of exercise mode, intensity, time and frequency). This can help patients understand the knowledge related to their disease, correctly understand the disease and judge their condition, build up confidence to overcome the disease, and cooperate with the doctor, under the guidance of the doctor to carry out the exercise treatment suitable for their own situation, so as to resume activities early, not only to achieve self-care, but also to reduce the psychological pressure and disease, early return to life, return to society, return to work, also. It is also beneficial to reduce the occurrence of heart disease complications, prevent the deterioration of heart disease, reduce the economic burden of society, families and patients, and greatly save medical resources. Cardiac rehabilitation treatment can be divided into four phases, each of which has a clear “goal” and “training intensity”. Inpatient Phase: This phase of rehabilitation should begin with a heart attack or admission to the hospital for a heart attack and continue throughout the hospital stay. The cardiac rehabilitation team will give the patient a progressive program that begins with easy activities, bed sitting, joint mobility and self-care, such as shaving. This is followed by walking in the ward or hallway and restricted stair climbing. Without these activities, the patient’s strength will quickly diminish. Early recovery period: Between 2 and 12 weeks after discharge from the hospital. Patients may be rehabilitated at a medical center near their home, return to a cardiac rehabilitation center, or follow the advice of a medical specialist for treatment at home. A specialized rehabilitation team will give patients advice on safe exercises to do at home, such as walking and calisthenics. Patients also need to learn how to eat healthily, stop smoking, adjust psychologically, resume sexual life and return to society. Later recovery period: medically supervised exercise and weight control. Experts say the so-called late recovery period is generally a procedure that begins about 6 to 12 weeks after hospitalization and typically lasts 3 to 6 months. During this time patients can exercise under medical supervision, especially in a rehabilitation center. Health education on nutrition, lifestyle, weight control and continued counseling continue. Lifetime Maintenance: At this point the patient has learned the correct exercise regimen and has begun to practice a healthy diet and lifestyle, so the patient no longer needs to exercise under medical supervision and the task at this stage is to maintain health status for life and receive regular follow-up visits.
