Nowadays, more people are having carotid ultrasound physical exams and are found to have carotid plaque or carotid stenosis. Today we look at those vessels that are prone to plaque and stenosis? Atherosclerosis refers to the deposition of lipids and other blood components in the arterial intima, the proliferation of smooth muscle cells and the increase in collagen fibers, resulting in atheromatous lipid-containing necrotic lesions and hardening of the vessel wall. Atherosclerotic lesions mainly involve large and medium-sized arteries. Therefore, all large and medium-sized arteries are at risk for atherosclerotic plaque formation. The major middle arteries include carotid, vertebral, coronary, renal, mesenteric, and femoral arteries. With the increasing maturity and popularity of carotid ultrasound technology, more and more people have detected plaque in the carotid artery. When arterial plaque is found in the carotid artery, it often indicates that the same lesion may occur in the blood vessels of the whole body, especially if there is arterial plaque formation in the blood vessels of the heart and brain and other important organs, it indicates a greatly increased risk of infarct diseases such as heart attack and brain attack. Therefore, carotid plaque is a window to determine vascular pathology and should be taken seriously. The more dangerous and common plaque vessels include the following arteries: 1. Coronary atherosclerosis caused by coronary artery atherosclerotic heart disease, referred to as coronary heart disease. It is one of the types of ischemic cardiomyopathy. 2, cerebral artery atherosclerosis is most likely to occur in the middle cerebral artery and basilar artery. It can cause shrinkage of brain tissue due to long-term blood supply deficiency. Patients are mentally retarded. In case of combined thrombosis, long softening of brain tissue occurs, and patients show aphasia, hemiparesis or even death. 3. Carotid plaque is a manifestation of carotid atherosclerosis, which occurs at the bifurcation of the common carotid artery, and is now considered to be closely related to the occurrence of ischemic stroke in the elderly. The mechanism of causing ischemic stroke may be: plaque enlargement and narrowing of carotid artery diameter causing intracranial hypoperfusion and plaque detachment to form emboli, leading to intracranial artery embolism. 4, renal artery atherosclerosis is not rare in the clinic, due to the lesion of the artery lumen narrowing or even obstruction, can cause renal infarction. Finally, I tell you, don’t be afraid of having plaque. First of all, to prevent damage to the inner surface of blood vessels, common causes are hypertension, hyperglycemia, smoking, alcoholism, staying up late, etc., which means to actively treat chronic diseases and change bad habits. Secondly, to reduce blood lipids as much as possible, and a reasonable diet such as limiting salt and less oil, eating more vegetables and fruits; strengthening exercise such as insisting on 30 minutes of aerobic exercise every day, etc. are the most effective methods and measures. Finally, it is to ask the doctor to do an assessment of the risk of cardiovascular disease occurrence, and if there is a greater risk, the corresponding drugs should be taken in a timely manner and for a long time to lower blood pressure, lipids and sugar.
