How big is a right subclavian artery plaque before it is harmful?

When the right subclavian artery plaque local thickening is greater than 1.5mm, it usually suggests a danger (hazard).
When the right subclavian artery plaque local thickening is greater than 1.5mm, the plaque can cause the corresponding blood vessel narrowing, when the plaque rupture can form thrombus; through the blood circulation cause cerebral infarction and acute myocardial infarction.
Therefore, patients with arterial plaque must pay attention to it; they can use lipid-lowering drugs under the guidance of physicians, such as atorvastatin, resuvastatin, etc., which can well lower the blood lipid and stabilize the plaque; meanwhile, they should maintain a low-salt and low-fat diet in their daily life, and do a moderate amount of physical exercise to promote the metabolism of blood lipids.
When the degree of stenosis reaches more than 70%, angiographic stent implantation can achieve the effect of stabilizing plaque and improving blood circulation at the same time; if you have any discomfort, you should go to the hospital in time and consult the physician for guidance.
