Patients with coronary heart disease cannot be cured by taking medication, but they can delay the disease and stabilize it. Mild coronary artery disease with atypical clinical symptoms can control lifestyle to reduce cardiovascular risk factors, such as having a low salt and low fat diet, and not eating high calorie foods such as animal offal and egg yolk. If you have hypertension or diabetes, you should control the primary disease, control blood pressure and control blood sugar. Patients with severe coronary artery disease should take oral medication on time and also control their lifestyle. If necessary, surgical interventions should be performed, coronary CT or coronary angiography should be performed to assess the severity of coronary artery stenosis and the extent of stenosis, and long-term oral medication should be considered to be able to delay the disease.
