Beyond Cholesterol: Unraveling Residual Lipidomic Risk in Cardiovascular Health.

Purpose of review: This paper reviews the existing literature on lipidomics as a tool for improved cardiovascular risk estimation in both primary and secondary prevention populations.

Recent findings: Detailed lipidomic signatures identified by mass spectrometry have been shown to enhance risk estimation for clinical CAD and the presence of subclinical CAD on CTCA in multiple large cohort populations. In patients with established atherosclerotic disease, ceramide and phospholipid-based risk scores improve prediction for recurrent cardiovascular events and cardiovascular death. Lipidomic profiles and lipidomic-enhanced risk scores have been shown to improve prediction of incident cardiovascular disease, recurrent cardiovascular events and cardiovascular death independent of traditional risk factors. Simplified risk scores utilizing the ratios of several ceramide species improve clinical utility, however resources and infrastructure limit widespread implementation. There are currently no therapeutics to address lipidomic risk aside from traditional risk factor modification.
