We additionally outline clinical strategies to reduce ASCVD risk in individuals with elevated Lp(a), including lifestyle optimisation, statin therapy, PCSK9 inhibitors, and aspirin in select populations. Emerging targeted therapies, including antisense oligonucleotides and siRNA-based agents, demonstrate up to 90% Lp(a) reduction and are currently being evaluated in large-scale cardiovascular outcomes trials.

Partial remission is often described colloquially as the 'honeymoon phase', a period lasting from months to years which is heterogeneous across patient groups. In this review, we discuss the immunometabolic events that may control the duration of the partial remission period by highlighting how glucose metabolism supports immune cell-driven inflammatory and autoimmune events. We thus propose that precise control of blood glucose within a healthy range delays the deleterious consequences that arise from autoimmune mechanisms within pancreatic islets, ultimately leading to the extension of the honeymoon phase. We further discuss data supporting the notion that managing blood glucose effectively also improves islet β-cell mass, function and maturity markers.
