The objective of this study is to investigate the potential association of the NLRP3 rs10754558 and CARD8 rs2043211 polymorphisms with the occurrence and prognosis of CAD. Gene polymorphisms were analyzed using the ABI PRISM-Snapshot multiplex method in 515 CAD patients and 401 control subjects. The serum level of IL-1β was investigated by ELISA assays. The clinical endpoints were evaluated during a median follow-up period of 32 months. The NLRP3 rs10754558 gene polymorphism was significantly associated with the occurrence of CAD, while the CARD8 rs2043211 gene polymorphism was not involved. Patients carrying G allele of NLRP3 rs10754558 had more severe coronary artery stenosis. Multivariable analysis revealed a significant association of the G allele with major adverse cardiac event. The serum IL-1β concentrations in patients with GG genotype were significantly increased compared with those in the patients with CC genotype. Our findings for the first time show that the NLRP3 rs10754558 polymorphism is involved in the occurrence of CAD in the Chinese Han population; and G allele can effectively predict clinical outcome of CAD. The G allele susceptibility to CAD is maybe associated with the increased level of serum IL-1β.
