Minor coronary artery stenosis is difficult to cure completely, but active treatment can relieve the patient’s symptoms. Coronary artery stenosis is generally due to plaque formation by atherosclerosis, and it is difficult to make the plaque disappear completely by drugs, but active treatment can slow down the progress of atherosclerosis and thus improve the patient’s symptoms; therefore, minor coronary artery stenosis is difficult to be completely cured, but it can make the patient’s symptoms be relieved. Currently, the drugs applied to coronary artery stenosis generally include statins, such as Rosuvastatin and Atorvastatin; antiplatelet drugs, such as aspirin and clopidogrel; in addition to active drug treatment, patients should also have a low-salt and low-fat diet, eat plenty of fresh vegetables and fruits, quit smoking and drinking, and exercise moderately. Patients with coronary artery stenosis should take medication and review under the guidance of a doctor, and should consult a doctor promptly if they feel unwell.
