Carotid artery plaque is divided into hard plaque and soft plaque. Soft plaque is less stable and easy to fall off. The formation of plaque is caused by the elevation of blood lipids due to the long-term consumption of fatty food, and the elevated blood lipids gradually attach to the inner wall of blood vessels to form plaque. Some plaques will be firmly bonded to the inner wall of blood vessels and have calcium deposits, which will form hard plaques. Soft plaques are easy to fall off, which does not mean they will fall off at any time. If plaque is found in the neck, strenuous activity is prohibited because strenuous exercise will increase plaque shedding due to vibration. If you have high blood pressure, you need to control your blood pressure actively, because high blood pressure is accompanied by fast heart rate, which will increase the speed of blood circulation and lead to the risk of plaque dislodgement, and your diet should be low-fat diet, and you should take oral statins to lower blood lipid drugs, which can stabilize and reduce plaque.
