European guidelines for the treatment of dyslipidaemias: New concepts and future challenges.

ABSTRACT

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of mortality and morbidity worldwide. Low-density lipoprotein cholesterol (LDL-C) is one of the most important causal factors for ASCVD. Based on the evidence of the clinical benefits of lowering LDL-C, the current 2019 European Society of Cardiology (ESC) and European Atherosclerosis Society (EAS) guidelines provide guidance for optimal management of people with dyslipidaemia. These guidelines include new and revised concepts, with a general tightening of LDL-C goals to be achieved, especially for patients at high and very high cardiovascular risk, based on the results of clinical trials of the recently approved drugs for the treatment of hypercholesterolaemia. However, some issues are still open for discussion. Among others, the concept of lifetime exposure to elevated LDL-C levels will probably drive the pharmacological approach and future guidelines. In addition, other factors such as non-HDL-C, apolipoprotein B, and lipoprotein(a) are becoming increasingly important in determining cardiovascular risk. Finally, there is the question of whether combination therapy should be used as the first step to maximise the effectiveness of the pharmacological approach, avoiding the stepwise approach, which is likely to have a detrimental effect on adherence. Given the ever-changing landscape and the availability of new drugs targeting other important lipids, future guidelines will need to consider all these issues.
