Coronary heart disease generally refers to coronary artery atherosclerotic heart disease, if patients with coronary artery atherosclerotic heart disease can control the development of the disease with medication, without stenting. However, if medication cannot control the development of the disease, or the degree of stenosis reaches more than 90%, stenting is required. Coronary atherosclerotic heart disease is a heart disease caused by narrowing or occlusion of coronary arteries. Patients may experience angina, chest pressure, shortness of breath and other symptoms. If the patient can effectively control the development of the disease through medication, stenting is usually not an option. However, if the patient’s non-surgical treatment is less effective and cannot effectively control the symptoms of the disease, or if the patient’s coronary stenosis reaches more than 90%, stenting is usually recommended. The stenting procedure involves the use of a balloon to inflate the stenosis and open up the narrowed blood vessel wall, thereby improving the symptoms of the disease. Once a patient is diagnosed with coronary atherosclerotic heart disease, he or she needs to take into account his or her own situation and actively cooperate with the doctor to take relevant treatment measures.
