A high LDL of 3.79mmol/L can be controlled by lifestyle intervention and medication. The appropriate level of LDL is <3.4mmol/L. 3.79mmol/L is a borderline elevated level, which is excessive for people with high risk factors such as hypertension, diabetes mellitus, and coronary heart disease and needs to be controlled. First of all, in terms of lifestyle, it is necessary to avoid oily diet, maintain appropriate aerobic exercise such as swimming, jogging, etc., and at the same time, quit smoking and drinking. If the effect of lifestyle intervention is not good, medication can also be used, statins such as atorvastatin, cholesterol absorption inhibitor ezetimibe, bile acid sequestering agent kalaurenine and so on.
