With the popularity of ultrasound examination, many medical checkups also include carotid ultrasound, many people will find that their carotid arteries have plaques of different sizes, sometimes suggesting soft plaques, sometimes hard plaques, so the medical checkup report suggests going to a big hospital for further examination, and tells the patients that they may suffer from cardiovascular disease and immediately go to the hospital to prescribe medicine to eat, which brings great mental and economic burdens to the patients. In fact, arterial plaque is similar to the scale accumulated on the wall of water pipe after using water pipe for a long time, if there are more blood sugar, blood lipid and other organic components in the blood, and if it is under high pressure for a long time, it is easier to form arterial plaque, if there is no high blood sugar, high blood lipid, high blood pressure and other factors, the structure and elasticity of blood vessel will be aged with age, just like the formation of pigmentation on the skin, which is a manifestation of aging. It does not require special treatment. Clinically, only those with risk factors, such as three high conditions, history of heart disease, family history, long-term smoking and obesity, or large plaque size and unstable plaque nature, need immediate treatment. For those patients who have no risk factors, good life and exercise habits, relatively small plaques and stable plaques, there is no need for medication.
