Patients with coronary heart disease are diagnosed and treated by doctors, some of whom take medication and some of whom undergo surgery, which is familiar to everyone. In addition, “exercise” treatment should be combined with the condition, and the rehabilitation doctor should guide the patient to do the right amount of beneficial exercise to promote the early recovery of coronary heart disease. What is the best way to achieve beneficial and moderate exercise? This requires another prescription – an exercise prescription. The exercise prescription is based on the patient’s condition, age, history of exercise and personal preference. The prescription will tell the patient what activities should be performed, how to control the amount of exercise and precautions. The following are the details of the exercise prescription for patients with coronary heart disease. Types of exercise Among the various exercises, walking, jogging, cycling or exercise bike, swimming, etc. are more suitable for patients with coronary artery disease. This is because these exercises are low to moderate intensity exercises, mainly endurance exercises. The energy metabolism of these exercises is mainly in the form of aerobic metabolism, so the medical term “aerobic exercise.” Long-term exercise can improve the body’s oxygen-carrying capacity, improve heart and lung function. Exercise volume It is mainly composed of exercise intensity, exercise duration and the number of exercises, the three can be coordinated with each other. Exercise intensity is an important indicator to ensure that the exercise effect does not cause danger, exercise intensity can be divided into three levels (low intensity, medium intensity and greater intensity). It is measured by the amount of oxygen consumed by the body during exercise. The greater the oxygen consumption, the greater the intensity of exercise. However, because it is difficult to clinically measure oxygen consumption, heart rate is often used as the most practical indicator of exercise intensity in actual exercise. This is because the heart rate is parallel to the oxygen consumption during exercise, and the measurement of heart rate is simple and easy to grasp. Patients only need to count their pulse for 15 seconds and then multiply it by 4 to get the heart rate per minute. However, this method is only suitable for patients without cardiac arrhythmias. The highest heart rate during low and moderate intensity exercise is expressed as 100 beats per minute and 100-120 beats per minute heart rate, respectively. In general, patients with coronary artery disease can achieve the purpose of exercise by engaging in low to moderate intensity exercise. Exercise frequency 3-5 times a week can achieve the purpose of exercise. Exercise timeliness Each time about 30-40 minutes. This includes 5-10 minutes of preparatory exercise; 15-20 minutes of formal exercise during which the expected heart rate can be achieved; and 5-10 minutes of finishing exercise. In general, a mild increase in systolic blood pressure (systolic blood pressure increase of no more than 20 mmHg) and an increase in heart rate (heart rate after the activity compared with the pre-activity ratio of no more than 20 beats/min or a maximum heart rate of no more than 120 beats/min during the activity) after exercise are normal reactions. However, if shortness of breath, angina pectoris, arrhythmia, dizziness, nausea, pallor, and prolonged fatigue and insomnia occur during the activity, it is normal. This indicates that the exercise is too much and should be reduced or suspended in the next exercise. The following points should be noted in the exercise of patients with coronary heart disease: 1, step by step: start with low-intensity exercise, do not reach the load at the first activity. 2, patients should choose the type and intensity of exercise according to their age, disease, physical condition, personal preferences and exercise base. Each activity can be alternated with various exercises. Such as walking and jogging alternately. 3.After illness or trauma, exercise should be suspended. 4, the elderly have many concurrent diseases, symptoms are not typical, more attention should be paid not to exercise too much and take into account the treatment of other diseases. Extend the preparation and finishing time during exercise. It is worth mentioning that the exercise prescription should be adjusted regularly according to the patient’s condition. Therefore, patients should always keep in touch with their doctors to change and adjust the exercise prescription.
