Dyslipidaemia

Principles

Higher LDL-c levels increase risk of CVD and reduction diminishes this risk (see table below for drugs used on this indication). For triglycerides (TG), there is no goal, but < 1.7 mmol/L (< 150 mg/dL) indicates lower risk and higher levels indicate a need to look for other risk factors. Statin treatment is recommended as the first drug of choice to reduce CVD risk in high-risk individuals with hypertriglyceridemia [TG > 2.3 mmol/L (> 200 mg/dL)]. Confirmation of hypertriglyceridemia needs to be verified with fasting lipid testing. Very high TG (> 10 mmol/L or > 900 mg/dL) increase risk of pancreatitis, fibrates should be used. Lipids testing should be performed every year in high or very high risk subjects and every 3-5 years in low and moderate risk subjects.

Less calories, more exercise, reducing bodyweight, and stopping smoking tend to improve (increase) HDL. Eating fish, reducing calories, saturated fat and alcohol intake reduce triglyceride levels. Reducing dietary saturated fat intake improves LDL-levels; if not effective, consider change of ART, then consider lipid-lowering medicine, see Prevention of Cardiovascular Disease (CVD).

Statins should be used by all those with established vascular disease and in persons who are not at LDL-c goals considering their level of CVD risk, irrespective of lipid levels, see Treatment Goals for LDL-c to reduce cardiovascular risk depending on CV risk estimation. In high risk persons with statin intolerance, drug-drug interactions between high intensity statins and ART, or those unable to reach LDL-c goals on statins and/or ezetimibe, a PCSK9 inhibitor and/or bempedoic acid should be considered. Icosapent ethyl (EPA) should be discussed in adjunct to statin in very high risk patients (post MI and diabetics with another CV risk factor with TGs > 150mg/dL or > 1.7 mmol/L.

i A statin is preferred first-line therapy; different statins have variable intrinsic LDL-c lowering ability
ii, iii, iv Target levels for LDL-c, see Prevention of Cardiovascular Disease (CVD). In persons where LDL-c targets are difficult to achieve, consult/refer to specialist Expected range of reductions of LDL-c: ii 1.5-2.5 mmol/L (60-100 mg/dL), iii 0.8-1.5 mmol/L (35-60 mg/dL), iv 0.2-0.5 mmol/L (10-20 mg/dL)
v, vi The ARV may v inhibit (statin toxicity, ↓ dose) or vi induce (= less effect of statin, ↑ dose gradually to achieve expected benefit ii, iii) the excretion of the statin
vii Exception: If used with DRV/r, start with lower dose of pravastatin
viii Pitavastatin has as yet no morbidity/mortality trial data to support its use but may have advantages of reducing immune activation and arterial inflammation, fewer drug-drug interactions, more HDL increase and less adverse glucose effect than other statins
ix This agent can be used for persons intolerant of statins or added to a statin when LDL-c reduction is inadequate despite maximally tolerated statin
x Data in persons with HIV available for evolocumab
xi Icosapent ethyl, a pure ester of eicosapentaenoic acid (EPA) from the omega-3 family, is indicated to reduce cardiovascular risk as an adjunct to statin therapy in subjects with myocardial infarction and/or people with diabetes at high cardiovascular disease risk with elevated triglycerides (< 10mg:dL or 1.7 mmol/L).
