Will new compounds be able to reduce the residual risk in high risk patients when treatment targets based on new ESC guidelines have been achieved (e.g. LDL-C < 70mg/dl)?

Despite widespread early intervention in acute coronary syndromes and complete revascularization of stenotic lesions complemented by aggressive polypharmacotherapy, still a high percentage of patients develop a secondary event.

This has been shown in various registries and recent data from the GRACE registry have suggested that we grossly underestimate long-term risk in these patients. Thus, despite all our current efforts there is room for improvement.

➢ A very active clinical research programme is delivering an important number of new potential therapeutic targets that

may be ready for trial testing.

 • Can OMICS technology help us out here in terms of new specific biomarkers taking advantage of the proteome, metabolome or the transcriptome?

 • What is the relevance of Mendelian Randomisation studies to investigate the potential causal role of biomarkers in the pathophysiology of disease and to identify and select new drug biotargets.

➢ One major question relates to the value of biomarker-guided and/or risk guided therapy and how to design appropriate trials to test these therapeutic strategies. Should therapy be targeted to patients with specific biomarkers profiles? e.g. low HDL, high inflammatory burden (elevated CRP), high Lp-PLA2 activity etc.?

➢ A fairly large number of lipid-associated new targets or targets reflecting other pathways of the complex atherosclerotic process are being evaluated in mechanistic imaging studies but also in large randomised controlled clinical trials looking for important cardiovascular endpoints. In all of these trials the standard of care is much better than seen in the real world situation. Thus, the question arises, whether these additional compounds will lead to a clinically significant reduction in cardiovascular events on top of optimal standard care.
