In case of mild atherosclerosis, active treatment usually does not affect the patient’s life expectancy; in case of severe atherosclerosis, it can lead to myocardial infarction, cerebral infarction and other diseases, which can greatly shorten the patient’s life expectancy. As age increases, atherosclerosis occurs in the arteries under the action of risk factors such as high blood lipids and high blood pressure, which can lead to narrowing of the lumen of the blood vessels. Mild atherosclerosis can cause inadequate blood supply to the heart muscle and brain, and through standardized drug treatment such as blood pressure and lipid lowering and active control of risk factors, the condition can be stabilized for a long time and generally does not affect the survival of patients. In contrast, severe atherosclerosis can cause serious diseases such as cerebral infarction and myocardial infarction, which can endanger the lives of patients, and some patients with severe myocardial infarction can die within a short period of time without active treatment. In addition to standardized drug treatment, patients with atherosclerosis need to quit smoking and alcohol, regular rest and rest, low-salt and low-fat diet, moderate exercise, and regular review at the hospital.
