1, maintain a proactive attitude towards recovery It is hard to imagine that the most important factor affecting patients’ recovery after surgery does not lie in medicine, but depends more on the patients’ attitude towards recovery. For example, many 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; their appetite is not good, so they do not want to eat, or simply ask the doctor to use intravenous nutrition. This negative view will only delay the disease. Studies have shown that early physical exercise after surgery can help patients recover sooner, so we ask patients to get out of bed and start functional exercise as soon as they are transferred to the general ward. Likewise, even if the appetite is low, it is important to eat as much as possible (not overeating, of course) and even to “take food as medicine” in order to recover faster. If the patient does not have a proactive attitude towards rehabilitation and just waits for the doctor to prescribe medication, various complications are likely to occur. 2. Active rehabilitation during hospitalization When a patient leaves the care unit, it means that the perioperative risk has been significantly reduced, and it also means the arrival of the active rehabilitation stage. In terms of diet, patients should try to ensure adequate nutritional intake. As mentioned before, it is common to lose appetite after surgery, and sometimes you even have to force yourself more or less to increase the amount of food you eat a little. Alternatively, taking the approach of eating less and more for a few more meals can be a proven means. Generally speaking, if you can eat half as much as you did before surgery in the early postoperative period, you can already meet the standard. Patients with diabetes, if their physical 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 gradually increase their activities 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. The activity level should be 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. You should actively cough and cough up sputum, do not be afraid to cough for fear of pain. When coughing, you can embrace pillows, etc., 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 hospital, patients should take the opportunity to rebuild good living habits. Works in this area have been sweated, and only a few aspects can be briefly mentioned. The first is healthy eating. The general principle is to appropriately reduce the intake of carbohydrates (that is, staple foods), minimize the consumption of high-fat and cholesterol diet, and enrich the variety of food intake. 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 exercise that suits you. Do not be in a hurry to increase your activity, it must be gradual, such as from indoor to outdoor, from short to long distance, from slow to brisk walking, 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 ruined, 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 medication 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.), which should also be taken orally regularly early after discharge, and often need to be carried when going out to control symptoms during angina attacks, and can be reduced and stopped if there is no recurrence for more than six months after surgery. Secondly, beta-blockers, such as metoprolol, etc., have a long-term application and have the effect of protecting heart function; anti-platelet drugs, such as enteric aspirin, Bolivar, and lipid-lowering drugs, such as various statins, are commonly used to stabilize atheromatous plaques and reduce the incidence of cardiovascular events, which should be taken for a long time and regularly, or even for life if physical conditions allow. There are also some drugs that need to be taken according to the patient’s respective condition and past medical history. For example, cardiac drugs of the digitalis class (e.g., digoxin, etc.) and diuretics (e.g., furosemide, ronolactone, etc.) may be used in patients with poor cardiac function. Patients with a previous 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 heart disease, hoping to achieve the purpose of stabilizing the patient’s condition, delaying the development of lesions, and extending the effective period of surgery. In addition, after discharge, patients must pay attention to review, establish a long-term follow-up 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 it upon yourself to stop medication at will.
