Carotid soft plaque is an accumulation of abnormal intravascular substances such as lipids, platelets, and leukocytes found on the inner wall of the carotid artery during carotid ultrasonography. Soft plaques are not smooth and irregular in shape, and are more likely to rupture and form blood clots than hard plaques. Once ruptured, blood clots may block the distal blood vessels, which may lead to serious consequences such as cerebral infarction, high blood pressure, venous embolism, and cerebral stroke, etc. Therefore, patients with soft carotid artery plaques need to be treated and controlled in a timely manner. Statins can cause plaque reversal in soft plaques, reducing the size of soft plaques, increasing their density, and transforming them into hard plaques that are more stable and less prone to rupture. When plaque is found in the carotid arteries, the level of risk still needs to be evaluated by a doctor to decide on a treatment plan, and regular follow-up visits should be made to determine the development of the plaque.
