The latest European and UK guidelines reflect the finding that there is no lower limit for LDL yet discovered, basically meaning the lower the LDL the lower the risk of future cardiovascular events. These recommendations come after new trials with lower targets showed better outcomes. As a result, millions of people taking statins around the world need to be looking more carefully at whether they are taking sufficient medication to lower their LDL to these new targets if the very best outcomes are to be achieved.
Risk category | Clinical | LDL-C (LDL) Target |
Very high risk | ASCVD, either clinical or unequivocal on imaging (CT scan included in these guidelines) Diabetes mellitus with target organ damage, long standing duration (>20 years), or associated with other risk factors eGFR <30 mL/min/1.73 m2 Familial hypercholesterolemia (FH) with ASCVD or with another major risk factor SCORE >10% | < 1.42 mmol/L (55 mg/dL) both in primary and secondary prevention < 1.03 mmol/L (40 mg/dL) in selected patients with recurrent ASCVD |
High Risk | Markedly elevated single risk factors, including total cholesterol >8 mmol/L (310 mg/dL), LDL-C >4.9 mmol/L (190 mg/dL) or blood pressure >180/110 mmHg FH without other risk factors Diabetes with a duration >10 years or with another risk factor eGFR 30-59 mL/min/1.73 m2 Calculated SCORE >5% and <10% | < 1.8 mmol/L (70 mg/dL) |
Moderate-risk | Younger patients (Type 1 diabetes mellitus <35 years; Type 2 diabetes mellitus <50 years) with diabetes mellitus duration <10 years, without other risk factors Calculated SCORE >1 % and <5%; | < 2.6 mmol/L (100 mg/dL) should be considered |
Low-risk | Low-risk calculated SCORE <1% fatal cardiovascular disease | < 3 mmol/L (116 mg/dL) |
ASCVD: atherosclerotic cardiovascular disease; CT: computed tomography; eGFR: estimated glomerular filtration rate; FH: familial hypercholesterolaemia; LDL-C: low-density lipoprotein cholesterol.

Some research suggests that non-HDL cholesterol may be a better predictor of heart disease than LDL cholesterol. This is because non-HDL cholesterol includes all the atherogenic lipoprotein particles, which transport triglycerides to tissues. These particles eventually turn into LDL. The NHS elected to simplify population blood testing for lipids, by measuring a random (non fasting) total blood cholesterol and HDL Cholesterol fraction. The term ‘non HDL cholesterol’ is widely used as an approximate equivalent to LDL and is simply derived by subtracting the HDL from Total Cholesterol.
For patients who have been diagnosed with an acute coronary syndrome, requiring bypass surgery or stent, or have CT Angiography and or raised FAI where the risk of future coronary events is increased, effective secondary prevention is required. The target LDL in such patients has been lowered to <1.8 mmol/L.
