With the improvement of living standard and change of lifestyle, the morbidity and mortality rate of coronary heart disease is on the increasing trend. Many patients with coronary heart disease have a misconception in their minds that a successful surgery means the condition is cured, but in fact, if the high-risk factors of coronary heart disease are not controlled, new lesions are likely to appear in the originally normal coronary arteries. Therefore, the precautions after coronary heart disease surgery become especially important. 1.Control of exercise The tolerance ability of each operated patient to exercise is different, related to heart function, degree of stenosis, stent opening and other factors. Some patients can gradually return to normal health after surgery, while some patients may not return to the original level. Therefore, post-operative exercise should be carried out gradually according to the doctor’s recommendation, and the amount of exercise should not be increased suddenly in a short period of time. 2.Regular review Regular review is a must for patients with coronary artery disease. Regular review helps to understand whether the blood pressure is stable and whether the indicators are normal to prevent the recurrence of coronary artery disease after surgery. Improper postoperative care may result in some danger signs, such as chest tightness and chest pain. Once these symptoms appear, be alert to the recurrence of the disease and need to be hospitalized again to facilitate the control of the disease. 3, quit smoking Quit smoking, there is no doubt about it. Cigarettes can not only accelerate the process of atherosclerosis, but also directly lead to coronary artery damage, spasm, etc.. Therefore, whether or not suffering from coronary heart disease, should be strictly quit smoking, including second-hand smoke. 4, change the lifestyle Coronary heart disease patients should pay attention to improve the lifestyle after surgery, a good routine, conducive to faster recovery, according to their actual situation, appropriate exercise, diet, to light food, eat more fresh fruits and vegetables. 5, actively prevent the risk factors of coronary heart disease The risk factors of coronary heart disease include smoking, hypertension, high blood pressure, high blood pressure, weight, age, genetic factors, etc. Postoperative patients should do a good job of prevention so as not to affect the recovery of the disease. 6, a good attitude to life Postoperative patients with coronary heart disease should usually maintain an optimistic mood, open-minded, not angry, generous to others, happy to do good deeds, family harmony, so as to maintain a calm state of mind, relaxation of blood vessels, and then with the use of drugs, angina and other attacks will also be reduced or disappear. You have to be open-minded and relaxed when things happen. After a successful recovery from coronary heart disease surgery is more desirable, you should not fail to pay attention to your daily life, if the disease recurs, it will bring considerable harm to your body.
