Coronary heart disease is a common disease among middle-aged and elderly people. Since there is no specific medicine to cure coronary heart disease so far, the main thing for patients is how to improve the symptoms and the quality of life. Rehabilitation is an effective method that is currently recommended internationally. Coronary heart disease rehabilitation is to help patients relieve symptoms, improve cardiovascular function and enhance quality of life through proactive training in physical, psychological, behavioral and social activities. It also actively intervenes in coronary heart disease risk factors to reduce the risk of reoccurrence. So, which patients can participate in rehabilitation exercises for coronary heart disease? The main ones are as follows: Stable coronary heart disease (including old myocardial infarction and stable angina) Occult coronary heart disease Patients after coronary artery bypass surgery Patients after percutaneous coronary balloon dilation. Exercise is mainly aerobic training, including walking, cycling, climbing, swimming, playing gateball, table tennis and badminton, etc. Rhythmic dance and traditional Chinese boxing exercises are also appropriate forms of exercise. The amount of exercise is the energy consumed during exercise, which is a key indicator of the effect of exercise. The sign of suitable exercise volume is: feeling comfortable when waking up in the morning and no fatigue. The total amount of exercise per week should be equivalent to walking 10 to 20 kilometers. The amount of exercise is composed of three elements: intensity, time and frequency. The easiest way to determine whether the intensity of exercise is appropriate is to sweat slightly while exercising and to breathe lightly faster but without affecting the conversation. Exercise time is the time it takes to reach training intensity each time, usually 10 to 30 minutes. Training frequency refers to the number of times per week training, generally 3 to 5?times per week exercise is enough. Each exercise must have three stages, namely, preparatory activities, training activities and end activities. Preparatory activities, also known as warm-up, the intensity of the activity is relatively small, the purpose is to fully active various joints, muscles and ligaments, but also to prepare the cardiovascular system. Training activities are divided into continuous training and intermittent training, the latter is more suitable for patients with coronary heart disease. Ending activities, also known as finishing, are designed to gradually restore the highly active cardiovascular system to a quiet state, generally using small-intensity relaxation exercises. Inadequate preparation and finishing activities are the most common causes of exercise accidents. In addition to this should also pay attention to: 1, to choose the appropriate exercise, both to achieve the training effect, but also easy to adhere to. To avoid competitive sports. 2, only when feeling good exercise. After a cold or fever to be in the signs and symptoms disappear for more than two days before resuming exercise. 3, pay attention to the impact of the surrounding environmental factors on the response to exercise, including: cold and hot climate to relatively reduce the amount of exercise and exercise intensity; wear loose, comfortable, breathable clothing and footwear; uphill to slow down; do not do strenuous exercise after meals. 4, patients should regularly check and amend the exercise prescription according to their personal ability to avoid overtraining. When medication changes, the exercise program should be adjusted. Physical examination should be conducted before participating in training. 5.Be alert to symptoms. If the following symptoms are found during exercise, stop exercising and seek medical attention promptly: upper body discomfort (including chest, arms, neck or jaw, manifested as soreness, burning, tightness or distension), weakness, shortness of breath, bone and joint discomfort (joint pain or back pain). 6, training must be persistent.
