Association between ADAMTS7 polymorphism and carotid artery plaque vulnerability.

ABSTRACT: Recent genome-wide association studies (GWAS) indicated that polymorphisms in ADAMTS7 were associated with artery disease caused by atherosclerosis. However, the correlation between the ADAMTS7 polymorphism and plaque stability remains unclear. The objective of this study was to evaluate the association between 2 ADAMTS7 variants rs3825807 and rs7173743 and ischemic stroke or atherosclerotic plaque vulnerability.This research is an observational study. Patients with ischemic stroke and normal control individuals admitted to Beijing Tiantan Hospital from May 2014 to October 2017 were enrolled. High-resolution magnetic resonance imaging was used to distinguish vulnerable and stable carotid plaques. The ADAMTS7 SNPs were genotyped using TaqMan assays on real-time PCR system. The multivariate logistic regression analyses were used to adjust for multiple risk factors between groups.Three hundred twenty-six patients with ischemic stroke (189 patients with vulnerable plaque and 81 patients with stable plaque) and 432 normal controls were included. ADAMTS7 polymorphisms of both rs7173743 and rs3825807 were associated with carotid plaque vulnerability but not the prevalence of ischemic stroke. The T/T genotype of rs7173743 [odds ratio (OR) = 1.885, 95% confidence interval (CI) = 1.067-3.328, P?=?.028] and A/A genotype of rs3825807 (OR?=?2.146, 95% CI?=?1.163-3.961, P?=?.013) were considered as risk genotypes for vulnerable plaque susceptibility.In conclusion, ADAMTS7 variants rs3825807 and rs7173743 are associated with the risk for carotid plaque vulnerability.

Project description:ImportanceIt remains unknown whether in an asymptomatic community-based cohort magnetic resonance imaging (MRI) measures of plaque characteristics are independently associated with incident cardiovascular disease (CVD) events when adjusted for carotid artery (CA) wall thickness, a measure of plaque burden.ObjectiveTo assess associations of CA MRI plaque characteristics with incident CVD events.Design, setting, and participantsThe Atherosclerosis Risk in Communities (ARIC) study is a prospective epidemiologic study of the incidence of CVD in 15 792 adults of which 2066 women and men were enrolled in the ARIC Carotid MRI substudy. ARIC participants were enrolled from 1987 to 1989, and the substudy was conducted between January 2004 and December 2005. Analysis began January 2017 and ended August 2020.ExposuresIncident CVD events during a median (interquartile range [IQR]) follow-up time of 10.5 (8.1-10.9) years were assessed.Main outcomes and measuresProportional hazards Cox analyses were performed to ascertain associations between MRI variables of CA plaque burden and plaque characteristics.ResultsOf 15 792 ARIC participants, 2066 were enrolled in the substudy, of whom 1256 (701 women [55.8%]) had complete data and were eligible for incident CVD analyses. Carotid artery plaques in participants with incident CVD events (172 [13.7%]) compared with those without (1084 [86.3%]) had a higher normalized wall index (median [IQR], 0.48 [0.36-0.62] vs 0.43 [0.34-0.55]; P = .001), maximum CA wall thickness (median [IQR], 2.22 [1.37-3.52] mm vs 1.96 [1.29-2.85] mm; P = .01), maximum CA stenosis (median [IQR], 5% [0%-22%] vs 0% [0%-13%]; P < .001), and when present, a larger lipid core volume (median [IQR], 0.05 [0.02-0.11] mL vs 0.03 [0.01-0.07] mL; P = .03), respectively. The presence of a lipid core was independently associated with incident CVD events when adjusted for traditional CVD risk factors and maximum CA wall thickness (hazard ratio, 2.48 [95% CI, 1.36-4.51]; P = .003), whereas the presence of calcification was not. The frequency of intraplaque hemorrhage presence in this population of individuals free of CVD at baseline who were not recruited for carotid stenosis was too small to draw any meaningful conclusions (intraplaque hemorrhage presence: 68 of 1256 participants [5.4%]). Carotid artery lumen area and maximum stenosis, which were overall low, were independently associated with incident CVD events when adjusted for traditional CVD risk factors, as anticipated.Conclusions and relevanceThe presence of a CA lipid core on MRI is associated with incident CVD events independent of maximum CA wall thickness in asymptomatic participants.
