Raised lipoprotein(a) (Lp[a]) cholesterol is highly prevalent affecting 1 in 5 individuals and is also frequently associated with the inherited condition familial hypercholesterolaemia (FH).1 It is associated with an increased risk of atherosclerotic cardiovascular disease, stroke and peripheral arterial disease, independent of traditional cardiovascular risk factors.2 Accurate measurement of circulating Lp(a) levels is currently a challenge3 and there are no licensed pharmacotherapies available for the management and treatment of elevated Lp(a).4
As with all health conditions, effective communication between the healthcare professional and patient is a key component of management. It is important that patients understand that raised Lp(a) is predominantly genetically inherited (>90%)2; therefore, other family members should be screened for the condition5 and made aware of the associated risks. Intensive treatment and management of other cardiovascular risk factors, such as low-density lipoprotein-cholesterol, blood glucose and blood pressure, is recommended. Patients should be mindful of other conditions that might affect their Lp(a) levels, such as chronic kidney disease.5 Lastly, they should be made aware of the factors that can raise their risk of heart disease and be encouraged to eat a healthy diet, maintain a healthy weight, take regular exercise, quit smoking and moderate their alcohol intake.5,6
In this supplement, Professor Paul Durrington discusses the role of Lp(a) in atherosclerotic heart disease and FH, covering the measurement and atherogenicity of Lp(a), along with its clinical management. Dr Saleem Ansari and Dr Jaimini Cegla examine the importance of measuring Lp(a) levels and the indications for Lp(a) testing. Professor Afzar Zaman and colleagues review the clinical utility of Lp(a) from an interventionist perspective, summarising the available data on the modulatory effect of Lp(a) on plaque morphology and recurrent ischaemic events. Finally, I will provide some real-world examples of patients with raised Lp(a) levels, illustrating the key principles of diagnosis and management.
