[ECS guidelines 2016 - dyslipidaemias].

Dyslipidaemia is a major cause of atherosclerotic cardiovascular disease and its progression towards clinical complications, such as acute coronary syndromes and stroke. In August 2016 the European Society of Cardiology (ESC) and the European Atherosclerosis Society (EAS) issued new joint guidelines for the management of dyslipidaemias. In these new guidelines, the concept of treating patients to a risk-based low-density lipoprotein (LDL) cholesterol target is reinforced. The task force considers LDL cholesterol as the primary target for dyslipidaemia treatment, whereas high-density lipoprotein (HDL) cholesterol is not recommended as a treatment target (based on the failure of HDL cholesterol elevation treatment strategies to reduce cardiovascular risk in recent studies). In patients with a very high risk for cardiovascular events it is recommended to treat to an LDL cholesterol target of less than 70 mg/dl. Moreover, the new guidelines now additionally recommend a > 50% reduction of LDL cholesterol in patients with very high cardiovascular risk patients and baseline levels between 70 and 135 mg/dl as well as in patients with high cardiovascular risk and baseline LDL cholesterol levels between 100 and 200 mg/dl. Statins are recommended as first-line medicinal treatment and the LDL cholesterol goals given imply the more frequent use of maximum tolerated statin therapy, in particular for patients with very high cardiovascular risk. Treatment with ezetimibe in patients with substantially elevated LDL cholesterol levels despite maximum tolerated statin therapy has now received a stronger recommendation (currently IIa recommendation). The guidelines also now include the potential use of the novel proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors and a recent ESC/EAS consensus document provides more detailed information on which patients can be considered for treatment with PCSK9 inhibitors, i. e. in particular patients with familial hypercholesterolemia and patients at very high cardiovascular risk who have markedly elevated LDL cholesterol levels despite maximum tolerated statin and ezetimibe therapy.
