Disease description:

Yesterday at noon, one of my colleagues suddenly experienced severe chest pain that was almost unbearable. After a hospital examination, it was found that he had a 70% narrowing of the heart artery. Is this condition considered coronary heart disease?

Doctor's answer (1)
Dr. Li Man
70% stenosis: If coronary artery stenosis reaches 70%, it is generally considered severe and classified as coronary heart disease. Patients need conservative treatment under a doctor's guidance, including oral medications such as lipid-lowering and antiplatelet agents to help slow the progression of coronary stenosis. If coronary stenosis exceeds 75%, surgical intervention with stent placement may be recommended.
