Cholesterol 5.32mmol/L alone is not serious, and the severity of the condition will increase significantly if combined with cardiovascular and cerebrovascular disease. The normal value of cholesterol is 0~5.7mmol/L, 5.32mmol/L is within the normal range, if there is no cardiovascular and cerebrovascular disease, no related risk factors, the condition is not serious, no need for oral drug treatment, usually through the diet to maintain cholesterol stability. Patients with combined cardiovascular and cerebrovascular diseases have stricter requirements for cholesterol and LDL to prevent the progression of atherosclerosis, and to control the level of LDL to <1.8mmol/L, which can effectively reduce the incidence of cardiovascular and cerebrovascular diseases. Patients with cardiovascular and cerebrovascular diseases should have their lipid levels evaluated, and those at high risk should have their lipids lowered intensively.
