The severity of 30%-40% stenosis in the anterior descending branches cannot be generalized and depends on the stability of the atherosclerotic plaque; there may also be unstable plaque in the coronary arteries, which can lead to the formation of thrombus in the coronary arteries in the event of plaque rupture.
If the plaque is soft, it represents an unstable plaque, which may suddenly rupture under stress, cold and mental pressure, leading to acute myocardial infarction and further increasing the risk of cardiac rupture, malignant arrhythmia and sudden death; if it is hard, it is a relatively stable plaque with a low risk of rupture; if the blood vessel is found to have become narrowed, it will require lifelong medication to slow down the development of the plaque.
It is recommended that patients should not judge or diagnose on their own based on one result, but should consult a doctor in a timely manner, who will analyze and treat the patient according to the specific situation.
