Coronary atherosclerosis refers to atherosclerotic changes in the arteries supplying blood to the heart muscle, resulting in narrowing or even occlusion of the lumen of the coronary arteries, resulting in symptoms of myocardial ischemia and heart attack. The main treatment is to control the patient’s blood pressure, blood lipids and blood sugar, quit smoking, apply coronary artery dilating drugs, such as isosorbide nitrate, nitroglycerin, etc., and also antiplatelet and lipid-lowering treatment to stabilize the coronary artery plaque and avoid the rupture of the coronary artery plaque, resulting in acute thrombotic bleeding.
