Coronary artery bypass grafting is one of the most effective treatments for coronary artery disease in clinical practice today. The correct and reasonable care after coronary artery bypass grafting is an important factor in determining the success rate and recurrence rate of the surgery. Coronary heart disease patients should do the following aspects of care after coronary artery bypass grafting. Wound should be cared for diligently After returning home, the wound should be checked frequently. If signs of infection (such as redness, swelling, pain and pus outflow) are found, the patient should go to the hospital for examination in time. The wound should be rinsed with water or antibacterial soap daily, and the exuding area should be covered with sterile dressing. Scientific arrangement of diet Daily intake of fruits and vegetables, more high-protein foods (such as meat, eggs, etc.) and foods with unsaturated fatty acids (such as corn oil, olive oil, etc.), and less foods with high saturated fatty acid content (such as chocolate, animal oil, etc.) should be consumed. Maintain a stable blood pressure after surgery, as high blood pressure will increase the burden on the heart and low blood pressure will prevent the blood flow in the “bridge”. If there is no contraindication, enteric aspirin should be taken for life as much as possible to prevent the formation of blood clots in the “bridge”. Regular follow-ups with electrocardiogram, isotope or coronary angiogram should be done to monitor the “bridge”. Drinking alcohol in small amounts and smoking is strictly forbidden. After surgery, you should drink alcohol in small amounts, not more than 50 milliliters per day for those who need to socialize. Alcoholic beverages should not be consumed while taking analgesics, sedatives and hypnotic drugs. Smoking can constrict blood vessels, increase heart rate and blood pressure, which is an important risk factor for heart disease, and long-term smoking can also damage the lungs, so smoking should be strictly prohibited. The first time a patient engages in sports after surgery, the pulse must be measured, and the exercise should be carried out strictly according to the exercise prescription, gradually and consistently. Before exercise, prepare for the activity. If discomfort such as chest tightness, chest pain, breath-holding, dizziness and rapid heartbeat occurs during exercise, stop the activity immediately and seek medical attention promptly. Rest more and avoid emotional excitement During the recovery period of 4-6 weeks after surgery, rest more and ensure 8-10 hours of sleep every day. All activities should be scheduled after sufficient sleep, and the amount of activity should be appropriate to not feel strained. Although guest visits can regulate emotions, they should be kept to a minimum for 2 weeks after discharge to avoid straining the mind.
