Atherosclerosis of the heart with severe stenosis requires implantation of a stent, and the specific treatment plan will be formulated as well as the results of coronary angiography. Atherosclerosis of the heart can lead to narrowing of the blood vessels, which needs to be evaluated by coronary angiography. Mild stenosis of the coronary arteries does not require stenting and can be treated with oral medications such as aspirin and atorvastatin. Severe stenosis of coronary arteries, such as stenosis greater than 75%, if accompanied by symptoms of angina pectoris, or sudden acute myocardial infarction, need to be implanted with stenting treatment to improve the stenosis of the vessel and increase the supply of blood to the coronary arteries, which may otherwise lead to myocardial necrosis. Patients with coronary atherosclerosis should be treated according to their condition and medicated under the guidance of a physician.
