Intracoronary stenting is an extremely effective method of treating coronary artery disease. Some patients who undergo interventional therapy believe that by implanting a stent in their blocked coronary artery, they are guaranteed a permanent cure. In fact, stenting does not completely eradicate coronary artery disease; it only removes the most severe lesions. Since the patient has undergone interventional treatment, it means that the patient’s coronary vessels are not healthy, and there may be a blockage in one part of the vessel this time, and there may be a new blockage in another part next time, so postoperative cardiac rehabilitation should not be neglected. The purpose of interventional cardiac rehabilitation is to exercise the function of the heart muscle so that the patient can resume a healthy life and return to society as soon as possible. It is well known that poor lifestyle is an important factor in the development of coronary heart disease. Another important purpose of cardiac rehabilitation is to proactively improve the function of the heart by establishing a good lifestyle and taking some medications to improve the patient’s quality of life. What are the components of cardiac rehabilitation? First of all, in order to prevent further development of coronary heart disease, especially to prevent complications such as thrombosis and re-narrowing after stent implantation, it is exceptionally important for patients to take relevant medications regularly after discharge from hospital. After stent placement by interventional procedures, all must be routinely treated with combined antiplatelet therapy, such as combined aspirin and clopidogrel. This is because the part of the vessel in which the stent is implanted is very susceptible to thrombosis in the absence of protection by effective antiplatelet agents, and the consequences are tantamount to another myocardial infarction. However, these drugs may affect platelets and white blood cells, so blood tests need to be repeated at the clinic during the administration period, especially at the beginning (about 1-2 weeks). If rashes, bleeding spots and bruises on the skin, and other bleeding conditions occur, promptly visit the hospital. In today’s increasingly widespread use of drug stents, antiplatelet drugs should be used in combination for at least one year under the guidance of a physician if there is no contraindication. All patients with stenting should take statins routinely. In fact, statins are used in patients with coronary artery disease not only to lower lipids, but because they are the only class of drugs available to slow the progression of atherosclerosis and stabilize its plaque. It is also important to control the factors that predispose to coronary heart disease and to adhere to medications related to lowering blood lipids, lowering blood pressure and treating diabetes. The World Health Organization has proposed four major factors of health, genetic factors account for 15%, social and natural environmental factors account for 17%, medical conditions are only 8%, and personal healthy lifestyle accounts for 60%. Change your lifestyle, have regular work and rest, exercise according to your actual situation, such as walking, doing radio gymnastics, etc., and maintain a normal weight. Rehabilitation exercises for patients with coronary heart disease should be phased and individualized, mainly divided into inpatient, recovery, and continuous periods. Generally, a personalized exercise program should be tailored by the doctor according to the patient’s condition and different conditions such as the patient’s cardiopulmonary function, and should be flexibly adjusted according to the patient’s recovery. Quit smoking and limit alcohol, pay attention to a light diet, and eat more fruits and green vegetables rich in vitamin C. Paying attention to controlling one’s emotions and maintaining an optimistic attitude towards life are also important elements of cardiac rehabilitation treatment. Chest tightness and chest pain are danger signs of recurrence of the disease. If this symptom appears within one month after the intervention, consider whether there is thrombosis. If chest tightness and chest pain appear within six months, especially if the symptoms are similar to those at the previous onset, restenosis (i.e., the site where the stent was placed is stenosed again) should be highly suspected to have occurred. Once such symptoms occur, patients are reminded that they need to be readmitted to the hospital for coronary angiography.
