1, maintain a proactive health attitude It is hard to imagine that the most important factor affecting the recovery of patients after surgery does not lie in medicine, but depends more on the attitude of the patient’s recovery. For example, many pairs of patients think that after surviving such a big operation, they must rest well in bed, plus the wound pain, so that they dare not move, or even cough; poor appetite, they are also reluctant to eat, or simply ask the doctor to use intravenous nutrition. This negative viewpoint commands to miss the condition. Studies have proven that early physical exercise after surgery helps patients recover early, therefore, we ask patients to get out of bed early and start functional exercise once they are transferred to the general ward. Likewise, even if the appetite is poor, try to eat (not overeating, of course), set, “take the meal as to eat|; in order to recover faster. If the patient does not have a proactive attitude towards recovery and just waits for the doctor to prescribe medication, instead, various complications are likely to occur. 2. Active rehabilitation during hospitalization The patient’s departure from the care unit means that the perioperative risk has been significantly reduced, which also means the arrival of the active rehabilitation phase. In terms of diet, the willing person should try to ensure adequate nutritional intake. As mentioned before, it is common to lose appetite after surgery, and sometimes one even has to force oneself more or less to increase the amount of food a little. Or adopting the method of eating less and more for a few more meals is also a proven means. Generally speaking, if the amount of food eaten in the early postoperative period is half of what it was before surgery, the standard can already be met. Patients with diabetes, if their health condition allows, can transition from semi-liquid to normal diet earlier, which is easier to regulate blood sugar. After entering the general ward, patients can start to get out of bed and increase their activities gradually according to their physical condition. If things go well, before discharge (5-7 days after surgery), most patients can walk in the corridor on their own for a short time, and the amount of activity is adjusted so that the patient does not feel too tired. Due to the intraoperative tracheal intubation, patients will have more or less sputum after surgery. Do not be afraid to cough for fear of pain. When coughing, you can embrace pillows and so on to limit thoracic movement, and family members should also actively pat the back to assist in sputum excretion. 3.Establish good living habits To some extent, coronary heart disease is a social disease and a disease closely related to personal behavior. After being discharged from the hospital, patients should use this opportunity to rebuild good living habits. This area of work is full of sweat, only a few aspects can be said individually. One is healthy eating. The general principle is to appropriately reduce the intake of carbohydrates (that is, staple foods), minimize the consumption of high-fat, cholesterol diet, and enrich the quality of eating. Second, appropriate exercise. The combination of diet and exercise to receive good results. After discharge from the hospital, it is still necessary to gradually increase the amount of activity. According to your own feelings, choose the appropriate way you should. Do not rush to increase the activity, must be gradual, such as from indoor to outdoor, from short distance road long distance, from slow to fast walk, etc.. If, during exercise, chest pain, shortness of breath, asthma, etc., or particular fatigue occurs, it should be stopped immediately. On the other hand, patients should not have psychological barriers, thinking that having had surgery, people are wasted, in fact, most patients can still achieve normal or near-normal exercise and quality of life. The third is to live a regular life, get enough rest, and quit bad habits (especially smoking). In fact, not only coronary heart disease, the recovery of various diseases are inseparable from this point. 4, post-operative drug treatment The full name of coronary heart disease is “coronary atherosclerotic heart disease”, as the name implies, its cause is atherosclerosis. Although coronary artery bypass surgery can restore coronary artery blood flow, it cannot remove the root of the disease, atherosclerosis, in this sense, coronary heart disease cannot be cured. Therefore, patients still need to insist on taking medications after surgery to prevent the continued development of atherosclerosis. Some of these drugs are vasodilators, including nitrates (such as nitroglycerin, isosorbide mononitrate, etc.), calcium antagonists (such as thiodiazepines, etc.) are also taken orally regularly in the morning after discharge, and often need to be carried when going out to control symptoms when angina attacks, and can be reduced and stopped if there is no recurrence for more than six months after surgery. Next is the beta-blocker, such as metoprolol, long-term application, has the role of protecting the function of the heart; anti-platelet drugs, currently commonly used enteric aspirin, Bolivar, and lipid-lowering drugs, such as a variety of statins, have the role of stabilizing atheroma, reducing the incidence of cardiovascular events, should be long-term, regular intake, such as physical conditions allow, or even lifelong use. There are also some drugs that need to be taken according to the patient’s individual condition and past medical history. For example, patients with poor heart function can use cardiac drugs like digitalis (such as digoxin, etc.) and diuretics (such as furosemide, rotenone, etc.) Patients with a history of hypertension should take antihypertensive drugs, and diabetic patients should pay attention to blood sugar control. In conclusion, in addition to drugs that act directly on the heart, most of the postoperative medications target various risk factors of coronary artery disease, hoping to achieve the purpose of stabilizing the patient’s condition, perpetuating the development of lesions, and extending the effective period of surgery. In addition, patients must pay attention to review after discharge from the hospital, establish a long-term review relationship with the doctor, and adjust the dosage of drugs and increase or decrease the type of drugs under the guidance of the physician. Do not take matters into your own hands and stop the medication at will.
