Cardiac angiography can more clearly see whether there are plaques and the degree of stenosis in the heart blood vessels. If the patient’s cardiac imaging suggests 70% stenosis and there are no obvious clinical symptoms and ECG abnormalities, it can generally be considered whether to be treated conservatively with medication or implantation of a stent; if the patient has recurrent symptoms of angina pectoris and 70% stenosis of the blood vessels, implantation of a stent can be considered.
Generally cardiography found that the stenosis is more than 75%, and combined with angina that is difficult to control by drugs, patients are recommended to put stents. If the stenosis is 70% and the indication for stent implantation is not reached, if the patient does not have recurrent symptoms such as chest tightness, chest pain, panic, cold sweat, etc., and the electrocardiogram does not show upward elevation of the ST-segment bow-back and myocardial markers are not elevated, the patient can generally be considered to be on medication for conservative treatment.
If the patient’s angina pectoris symptoms such as chest tightness and chest pain recur and worsen, cardiac imaging suggests that the stenosis is 70%, stent implantation can generally be considered.
If the patient’s cardiac imaging suggests 70% stenosis, it is recommended to go to the hospital in time to see the doctor, and follow the medical advice after evaluating the patient’s individual situation.
