What is coronary heart disease? Coronary heart disease is short for atherosclerotic heart disease of the coronary arteries. Coronary arteries are the blood vessels that supply the heart with its own blood. When the coronary arteries become severely atherosclerotic or spastic, narrowing or occluding the coronary arteries, it can lead to myocardial ischemia and hypoxia or infarction, which can be seriously life-threatening. Atherosclerosis can occur in any branch of the coronary artery, but the left anterior descending branch is the most common, followed by the right coronary artery and the gyrus branch. Simultaneous involvement of these three branches of the artery is clinically known as coronary artery disease with three branches of lesions. Risk factors for the development of coronary heart disease? Age and gender; hypertension; hyperlipidemia; diabetes; smoking; obesity; lifestyle; others: genetics, alcohol consumption, environmental factors, etc. What are the treatment methods of coronary heart disease? (1) “Preventers clearing” – drug therapy: drug therapy is the most necessary, most commonly used and effective treatment method among many coronary heart disease treatment methods, and is the first choice. (2) “Rerouting” – coronary artery bypass grafting: referred to as coronary artery bypass surgery, a section of the patient’s own blood vessels as a vascular bridge, one end of the bridge is connected to the “upstream” of the infarct site, and the other end is connected to the “downstream” of the infarct site. The other end of the bridge is connected to the “downstream” side of the infarct. In this way, the blood can pass through the bridge, bypassing the blocked section and resupplying energy and oxygen to the myocardium in the area it innervates. (3) “Clear the blockage” – coronary angioplasty: or called coronary intervention, the most widely used interventional procedures are thrombolytic therapy, percutaneous transluminal coronary angioplasty and coronary stenting. Health guidance after coronary artery bypass grafting? (1) Diet: low-fat, low-sugar, salt-restricted diet is the mainstay. You should quit smoking, limit alcohol, avoid overeating, be optimistic, and moderately control blood pressure, blood sugar, blood lipids, and control weight. (2) Activity: Gradually, patients should participate in outdoor activities moderately after surgery, to the extent that they can tolerate and do not feel fatigue and discomfort. (3) Wound recovery: The stitches of the chest incision will be removed one week after surgery, and the sternum should not be lifted more than 10 to 15 pounds for the first three months. Due to the recovery of the wound, it takes about six weeks, (each individual varies slightly) the healing of the sternum takes about three months, during this recovery process, although your sternum will not crack with light activity, it is still necessary to protect them. (4) Medication: Take your medication as prescribed by your doctor and on time. Please do not stop taking your medication without your doctor’s permission. Postoperatively, you will also have to keep taking oral anticoagulants such as aspirin to prevent platelet aggregation, and betalactam to improve diastolic function of the heart. (5) Review: When you leave the hospital, you should make an appointment with your doctor when you will have a review. If you have any discomfort while you are resting at home, please contact your local hospital or the hospital where you had your surgery as soon as possible. A full review is usually due 3-6 months after surgery.
