LDL levels do not tell the entire story about cardiovascular health, ie. depending on your genetics, diet (eg. keto diet), lifestyle, and your blood triglycerides : HDL : LDL ratios, high LDL levels might be actually be indicative of good cardiovascular health, not poor cardiovascular health (as most doctors, including cardiologists, automatically assume, an erroneous over-simplification).
