The importance of exercise in heart bypass surgery The main purpose of heart bypass surgery is to reduce myocardial ischemia and improve the quality of life. The traditional belief is that the surgery will damage the body’s vital energy, so it is logical that you need to rest in bed for a long time after the surgery and be as inactive as possible. Doctors believe that such an approach loses the value of having bypass surgery and not only makes the body weaker, but also allows the heart and blood vessels to lose reserve function due to lack of exercise. After coronary artery bypass surgery, most of the venous bridge vessels become occluded within 5 years, and the internal mammary artery bridge vessels have a high long-term patency rate, but the risk of occlusion increases after 10 years. Exercise combined with medication can significantly reduce the risk of bridge vessel occlusion. Exercise rehabilitation therapy under the guidance of physicians allows the body to gradually improve its tolerance and can restore the working life status before the onset of the disease, or even better quality of life than before the treatment. Cardiac rehabilitation should start before surgery. The main purpose is to enhance physical fitness and organ function. The specific exercise methods are as follows: 1. Pre-operative: Doctors recommend patients to practice deep breathing and coughing exercises every day before surgery. As well as simple strength exercises, such as upper limb fist clenching exercises and alternate lower limb elevation exercises in bed to promote increased lung capacity. 2.Postoperative: Generally, the ventilator can be withdrawn one day after surgery and rehabilitation treatment can be started. a 2~3 days after surgery, lower limbs can be raised with the help of family members and fist clenching exercises can be done. b 4~7 days after surgery, bed and bedside exercises can be performed under the guidance of the doctor. Before discharge from the hospital, the doctor will conduct a comprehensive evaluation of all postoperative indicators, after which an individualized cardiac rehabilitation prescription will be given. For patients just discharged from the hospital with a very successful surgery, a reasonable exercise schedule in the absence of complications and comorbidities of other diseases is: 1. Start with 25 minutes a day, 10 minutes of slow walking before and after, and 5 minutes of slightly faster pace in between. 2, 5 to 7 days a week, feel slightly short of breath can be. Do not be brave, there is obvious discomfort should stop exercise. 3, the second week if there is no discomfort, the exercise time can be increased to 30 minutes, before and after each 10 minutes of slow walking, in the middle of a slightly faster walking time increased to 10 minutes. Later every week or every 2 weeks will be slightly faster walking time in the middle increased by 5 minutes. 4, about 1 and a half months to achieve a daily exercise, each time 50 minutes, that is, before and after each 10 minutes of slow walking, in the middle of the brisk walking time to 30 minutes. In principle, the examination suggests that when the cardiopulmonary function permits, do not bed rest.
