Abstract

Previous studies have established that coronary artery disease is associated with excess inflammation. These studies have shown an elevation of both pro and anti-inflammatory cytokines in sufferers of coronary artery disease. There is increasing interest in the role played by the inflammasome Nod Like Receptor family pyrin domain containing 3 (NLRP3) in the aetiology of coronary artery disease. Increased severity of coronary artery disease correlates with higher levels of expression of NLRP3. Does NLRP3 polymorphisms play a role in the aetiology of coronary artery disease? In a cohort of Vietnam War (n-299) veterans who have been previously exposed to trauma, NLRP3 polymorphisms were analysed for association with coronary calcium scores using analyses of variance. Independent t-test was used to analyse genotypes. In samples with a small representation of minor homozygotes, genotypes were combined and analysed using independent t-test. If any of the genotype analysis suggested the potential for a dominant or a recessive model the model was further explored. Hardy-Weinberg Equilibrium was calculated using Hardy-Weinberg equilibrium calculator including analysis for ascertainment bias. The NLRP3 polymorphism, rs10159239 was significantly associated (p = 0.001) with a higher raised coronary calcium score. The Single Nucleotide Polymorphism rs10159239 was examined by logistic regression with known risk factors for Coronary artery disease and remained significant (0.035). This is the first time rs10159239 A-allele has been associated with raised coronary calcium score. This is the first time rs10159239 A-allele has been associated with raised coronary calcium score. Further research is needed to replicate our results in larger well-characterised cohorts. Copyright © 2019 Elsevier B.V. All rights reserved.
