The traditional treatment for coronary artery disease is medication, which is used to dilate the narrowed coronary arteries and improve the blood supply to the heart before heart surgery. There were also treatments for comorbidities, such as aspirin, to prevent blood clots from forming. Surgical bypass surgery was introduced in the 1960s, more than 60 years before coronary stents. Is age a measure of whether a heart bypass is done or not? Back in 2012, the first space hero in human history to walk on the moon, American astronaut Armstrong died at the age of 82 due to complications from heart bypass surgery. Patients with coronary heart disease, especially the elderly, are very worried about this type of surgery. In fact, age is not a criterion to measure whether a patient can undergo heart bypass surgery, but it is certain that the older a patient with coronary heart disease is, the worse the body’s ability to recover and the more likely complications will arise. Those who are ready to undergo heart bypass surgery must also ensure that their liver and kidney functions, respiratory system, blood sugar, blood pressure and other indicators meet the requirements. Complications after heart bypass surgery in the elderly are mainly focused on two aspects: one is the respiratory complications brought about by the trauma caused by the ventilator to the human respiratory system; the second is the negative impact of the surgery itself on the human liver and kidney functions. In addition, patients with coronary artery disease who also have hypertension and diabetes may also have complications after bypass surgery. Therefore, patients with coronary artery disease who have undergone heart bypass surgery should take anticoagulant drugs and rest for at least 2 weeks before leading a normal life. It may take longer if you want to completely regain your former vitality. Also, special attention should be paid to personal care after surgery. What should I take care of after heart bypass? After the surgery, patients with coronary artery disease must strictly quit smoking, and if they have combined diabetes, they should strictly control their blood sugar, increase the intake of high quality protein and various vitamins, and avoid high-fat and high-calorie foods in their diet. After surgery, the immunity of coronary heart disease patients will also be greatly reduced, in the recovery period should avoid going to crowded places, do a good job of keeping warm, indoor to strengthen the gout, to avoid the occurrence of colds. After the body gradually improves, some outdoor exercises should be increased, but should not be rushed, so that the heart has a slow adaptation process. If symptoms such as chest tightness, chest pain and shortness of breath occur when exercising, you should stop immediately. Finally, it is to remind all postoperative coronary heart disease patients that it is best to record blood pressure and pulse count regularly every day, and if you find serious symptoms such as rapid beating, dizziness and weakness, you should seek medical attention immediately. Even if there are no symptoms, perhaps regular review at the hospital and provide some monitoring data of the usual body, so that the doctor can adjust the medication in a targeted manner.
