Associations of Circulating ANGPTL3, C-Terminal Domain–Containing ANGPTL4, and ANGPTL3/8 and ANGPTL4/8 Complexes with LPL Activity, Diabetes, Inflammation, and Cardiovascular Mortality

CirculationPublished

  • Prospective cohort study with mechanistic in vitro study
  • two cohorts (LURIC, getABI)
  • recombinant protein assays

Authors' conclusion

However, ANGPTL3/8, LDL-C, and triglyceride levels were not associated with cardiovascular death in the LURIC and getABI cohorts. In contrast, concentrations of ANGPTL4/8 and particularly CD-ANGPTL4 were positively associated with inflammation, the prevalence of diabetes, and cardiovascular mortality.
