Coronary atherosclerosis is a cardiovascular disease, and if you want to see a doctor, you need to go to cardiovascular medicine. Coronary atherosclerosis can cause narrowing of blood vessels, resulting in inadequate blood supply to the heart muscle and thus angina pectoris. In severe cases, it can also lead to local plaque erosion and rupture, resulting in platelet aggregation, thus blocking the blood vessels and causing continuous ischemia and hypoxia to the heart muscle, leading to myocardial infarction. Therefore, patients with coronary atherosclerosis should be given lifestyle interventions, lipid-regulating drugs to stabilize local plaques, anti-platelet drugs to prevent local thrombosis, and active control of risk factors for coronary heart disease, such as hypertension, diabetes, hyperlipidemia, etc.
