In hyperlipidaemia, meaning elevated blood fats, we distinguish the neutral fats (triglycerides) and the colloquially known “bad” cholesterol (LDL cholesterol). Healthy people with no vascular risk can have a value up to 160mg/dl LDL cholesterol and up to 200mg/dl triglycerides (in fasting serum) to be considered normal. If there is a vascular risk, such as arteriosclerosis with constrictions, these values especially LDL cholesterol should be reduced to less than 100mg/dl (sometimes even less than 70 mg/dl). Additionally to the elevated LDL cholesterol, further, rarer lipid protein particles (such as lipoprotein(a)) can result in arteriosclerosis.
