Atherosclerotic heart disease refers to the heart disease caused by atherosclerosis of the coronary arteries, which causes narrowing or occlusion of the lumen, resulting in myocardial ischemia, hypoxia or necrosis, referred to as coronary heart disease. This disease is gradually becoming younger, and poor lifestyle habits and family history are the main causes of this disease. The treatment of coronary heart disease is mainly divided into conservative drug therapy and revascularization therapy. The kind of plan developed for the patient depends mainly on the actual severity of the patient’s condition. First of all, it is recommended that patients should develop good living habits, make sure to have a low-salt and low-fat diet, regular rest and rest, eat more fresh fruits and vegetables, keep a happy mood, and exercise appropriately to lose weight during weekdays. If the patient is suffering from stable angina, he can choose to use anti-atherosclerotic, anti-platelet, lipid-lowering and plaque stabilizing drugs, such as Bayer aspirin and Lipitor for secondary prevention. If there are still episodes of discomfort while taking these two drugs, they can be combined with additional drugs such as betalactam and isosorbide mononitrate to help further control angina attacks. For patients with unstable angina who have frequent episodes of discomfort, it is best to do a coronary CT or coronary angiography if economic conditions allow. If there is a serious stenosis problem, then you should choose to do percutaneous coronary intervention, and if the vascular disease becomes diffuse, you can combine it with coronary artery bypass grafting if necessary. It should also be combined with dual antiplatelet therapy, in which anti-platelet drugs such as Bolivar or Tegretol should be used in combination with Bayer aspirin. If the disease is recurrent but not eligible for coronary stenting, I can combine anticoagulation and antiplatelet therapy with drugs that improve myocardial nutrition and exercise tolerance, such as trimetazidine, or drugs that relieve coronary spasm, such as the calcium antagonist Habersham. In the early stages of coronary heart disease, we should do a good job of secondary prevention so that we can better prevent further progression of coronary heart disease. Secondary prevention can not be terminated overnight, but patients need to take care of their bodies, quit smoking, limit alcohol, exercise, control blood sugar and blood pressure, and take secondary preventive drugs orally on time, so as to truly prevent the aggravation of coronary heart disease.
