Many patients with dyslipidemia can mostly be improved through diet, such as trying not to eat animal oils, minimizing the consumption of animal offal, and foods such as egg yolks. If cholesterol is not well controlled through diet for a long time, you will need to take lipid-lowering medication for a long time. Long-term high blood lipids change over time, and the rate of cardiovascular and cerebrovascular lesions increases year by year. Because many coronary heart disease, cerebral infarction, and other cardiovascular diseases in the elderly are mostly caused by atherosclerosis, and one of the very important risk factors is high blood cholesterol, long-term use of related medications is recommended for this group of patients. Although the cost of medication will be higher, the risk or family burden generated will be more serious if it causes brain infarction, heart infarction and other hazards, rather than outweighing the loss. Therefore, long-term lipid substandard should definitely take long-term lipid-lowering drugs to reduce cardiovascular events.
