If the stenosis of the right coronary artery reaches 70% and is accompanied by ST-segment depression on the ECG, and there are uncomfortable symptoms, stent implantation is necessary, but the specific conditions should be followed by the doctor’s advice and standardized treatment under the doctor’s guidance. 1. If the stenosis of the right coronary artery reaches 70% and is accompanied by ST-segment depression on electrocardiogram, frequent feeling of chest tightness, frequent angina pectoris, and a positive plate test, stenting is needed to relieve the symptoms of myocardial ischemia. 2. Right coronary artery stenosis of up to 70%, measurement of flow pressure distal to the stenosis (FFR) is performed during angiography. If the distal blood flow is not reduced, stenting can be withheld for the time being. Symptoms can be relieved by oral medication first, but standardized secondary coronary artery disease should be performed for prevention. Patients with right coronary artery stenosis need to undergo appropriate professional examination in regular hospitals and have their condition assessed by doctors for diagnosis, so as not to miss the best time for treatment and delay their condition.
