What is the best standard of lipid control to prevent cardiac and cerebral insufficiency?

LDL-C target values: patients with myocardial infarction, stroke, etc. are at very high risk and LDL-C should be <1.8 mmol / L. Patients with high risk factors such as obesity, diabetes and hypertension should have LDL-C <2.6 mmol / L.
Statins are the preferred lipid-lowering drugs, and LDL-C levels should be reduced by at least half for those who cannot meet the LDL⁃C target.
