The number of years a patient with soft carotid plaque can live is related to the specific condition and the measures taken, and cannot be generalized. There is a certain risk of soft plaque in carotid artery. Soft plaque means that the plaque formation time is relatively short, for not forming obvious atherosclerotic changes. However, because of its soft texture and may not be completely fixed well in the carotid artery, when the patient is emotional, blood pressure is elevated and blood flow is fast, it may cause the soft plaque of carotid artery to fall off and cause acute cerebral infarction, intracranial pressure rise and other diseases, which may immediately endanger the patient’s life if not treated in time. If such patients prohibit smoking and alcohol, avoid high-salt, high-sugar and high-fat food, exercise appropriately, avoid overexertion, and use antiplatelet and lipid-lowering and glucose-lowering drugs to stabilize the plaque under the guidance of vascular surgeons, and review regularly, they can effectively prevent the soft plaque from shedding plaque, which usually does not affect the life expectancy of patients and is no different from normal people. In addition, it is suggested that such patients should pay attention to keep their mood relaxed, avoid anxiety and over-excitement, especially should avoid anger, and need to pay attention to light diet and drink more water in daily life to avoid further progress of the disease.
