Abstract

Objectives. Prehypertension is an early stage of hypertension that is characterized by inflammatory factors. Inflammation also plays an essential role in the development of coronary atherosclerosis (CAS). The present study evaluated the NALP3-inflammasome and its related genes, NLRP3, NOD2, and CARD8, using SNP linkage and gene haplotypes in prehypertensive patients. Methods. A total of 576 patients with prehypertension and suspected coronary heart disease (CHD) were enrolled. According to coronary angiography, patients were divided into two groups: arterial stenosis <50% of the diameter (control) and arterial stenosis >50% of the diameter (case). Fifteen polymorphisms in the NOD2, NLRP3, and CARD8 genes were analyzed, and serum levels of C-reactive protein (CRP) were measured. Results. When comparing allele frequencies, none of these 15 SNPs in NOD2, CARD8, and NLPR3 genes showed a significant difference using multiple logistic regression. However, the CTACATAA (p = 0.0064) and CCACATAG (p = 0.0126) haplotypes of the NOD2 gene SNPs were significantly different between cases and controls. Conclusions. Although our study excludes a significant association of selected SNPs in these genes with CHD in prehypertension patients, this work suggests that the CTACATAA and CCACATAG haplotypes were associated with CHD in the NOD2 locus. This work suggests that the CTACATAA and CCACATAG haplotypes were associated with CHD in prehypertension patients in the NOD2 locus.
