Coronary heart disease is not completely curable. Coronary artery disease refers to the narrowing and blockage of coronary vessels due to various reasons, resulting in ischemia, hypoxia and necrosis of the heart muscle. When using medication, it is not possible to completely clear the blockage of blood vessels and reverse the damage, and coronary artery disease is a continuously progressive disease, which can only be controlled by medication and surgery to relieve the patient’s symptoms. When a patient with coronary heart disease has an acute attack, nitrate preparations, such as nitroglycerin and isosorbide nitrate sublingual, should be used in a timely manner to relieve angina as soon as possible. Anti-platelet drugs and secondary prevention drugs should also be taken to control the disease progression to avoid further aggravation of arterial blockage to the greatest extent possible. When the effect of drug treatment is not good, the disease control effect is not good, and the blockage of blood vessels has reached 70%, interventional treatment and bypass surgery should be used in time to improve the degree of coronary artery stenosis. In addition, when patients have risk factors such as hypertension and hyperglycemia, they should also be controlled in a timely and appropriate manner to avoid aggravating the symptoms of coronary heart disease. In daily life, attention should also be paid to diet and exercise. Diet should be low in salt and fat, cooked with vegetable oil as much as possible, and some red meat, such as lean meat from beef, lamb and chicken, can be consumed. Consume more fresh fruits and vegetables, especially fruits with high potassium content, which can help resist atherosclerosis. Strenuous exercise should be avoided as much as possible to reduce the risk of inducing angina pectoris, myocardial infarction, and even sudden death.
