Few studies are available in human populations investigating involvement of vascular inflammation and oxidative stress-related dysfunctional transformation of high-density lipoprotein (HDL) in establishing cardiovascular disease (CVD) risk. To this end, the current work investigated a subgroup of post-infarction patients at high-risk for recurrent events defined by high levels of HDL cholesterol (HDL-C) and concurrently high levels of C-reactive protein (CRP). Thrombospondin-4 (TSP-4), a matricellular protein of vessel walls associated with inflammation, was investigated in terms of CVD risk using multivariable modelling with a well-characterised functional genetic polymorphism of THBS4 (A387P, rs1866389) along with previously demonstrated risk-related functional genetic polymorphisms of CYBA (C242T, rs4673) and CETP (TaqIB, rs708272), and a set of blood markers. Results revealed risk-association for the gain-of-function P-allele of the THBS4 polymorphism (hazard ratio 2.00, 95% confidence interval 1.10–3.65, p=0.024). Additionally, von Willebrand factor was associated with D-dimer levels in the higher-risk P allele patients suggestive of a connection between endothelial dysfunction and thrombogenesis. In conclusion, TSP-4, a matricellular protein involved in regulating vascular inflammation, plays a role in establishing recurrent coronary risk in post-infarction patients with high levels of HDL-C and CRP. Further studies should focus on additional effects of vascular inflammatory processes on anti-atherogenic functionality of HDL particles.
