Lipids are not necessarily associated with carotid plaque. Carotid plaque despite not having high blood lipids may be associated with hypertension, age, hypercholesterolemia, smoking and other factors. 1. Hypertension: Since hypertension carries a higher risk of stroke, generally four times that of a person with normal blood pressure, it may also increase the risk of carotid plaque. 2. Age: With increasing age, the process of atherosclerosis of blood vessels intensifies, with the gradual development of plaque and narrowing. 3. Hypercholesterolemia: usually associated with the development of carotid artery stenosis, so can increase the risk of carotid plaque. And patients can reduce the risk of stroke after consuming statin drug therapy, and have a controlling effect on the progression of blood vessel wall thickness and intima-media thickness. 4. Smoking: Smoking usually increases the risk of myocardial infarction, stroke and death, and the severity of carotid artery disease is also closely related to smoking. It is recommended that patients with carotid artery plaques should identify the cause of the disease in a timely manner, and then follow the doctor’s instructions to take reasonable treatment.
