Clinically, there is no such thing as the four principles of coronary heart disease treatment; it can be controlled under the guidance of physicians to control coronary atherosclerosis, reduce myocardial oxygen consumption, improve myocardial blood supply, and heart transplantation. 1. Control of coronary atherosclerosis: the main measures are lifestyle regulation, low-fat diet, moderate exercise, weight control, etc., but also the appropriate use of lipid-regulating drugs, such as atorvastatin, reservastatin, etc., antiplatelet drugs, such as aspirin, tegretol and so on. 2. Reduce myocardial oxygen consumption: firstly, pay attention to rest, control the amount of exercise, secondly, reduce myocardial preload, control high blood pressure through antihypertensive drugs, and then control the heart rate and myocardial contractility, available β-blockers and calcium channel blockers. 3. Improve myocardial blood supply: Interventional therapy can also be used to implant stents or coronary artery bypass grafting surgery to relieve coronary artery stenosis and restore myocardial blood supply. 4. Heart transplantation: Patients with serious conditions who are unable to undergo interventional or bypass surgery can only choose heart transplantation. After the discovery of coronary heart disease, we must go to the regular hospital in time, and start the treatment as soon as possible, do not blindly use medication on your own, so as not to delay the condition.
