Research Article: Association between Triglyceride-Glucose Index and carotid plaque in Japanese population: a cross-sectional study
Abstract:
Objective Previous studies linking Triglyceride Glucose (TyG) Index to carotid plaque have yielded inconsistent results. Moreover, related studies on the population of Japan are rare. This study aims to provide further results. Design A hospital-based cross-sectional study. Setting The Shin Takeo Hospital. Participants We assessed 1904 Japanese participants (988 men and 916 women) whose mean age was 57±11.9 years, and those participants underwent health check-ups at Shinbuf Hospital at Shin Takeo Hospital from 1 April 2016 to 31 October 2017. Methodology Carotid plaque, triglyceride and fasting glucose and other relevant indicators were collected. We used ultrasonography to evaluate carotid plaque. A multivariable logistic regression model and generalised additive model were used to evaluate the association between the TyG Index and carotid plaque. Subgroup and interaction analyses were validated for the consistency of these correlations. Results Following the adjustment of traditional carotid plaque risk factors, the non-linear relationship between the TyG Index and carotid plaque was investigated. Using a two-piecewise regression model, we calculated the inflection point to be 9.06. The OR and 95% CIs for the inflection points on the left and right sides were 1.70 (1.27 to 2.29) and 0.88 (0.52 to 1.47), respectively. According to the variables tested, the interactions between the TyG Index and all subgroup factors were analysed and significant interactions were not observed. Conclusion In individuals who underwent a comprehensive check-up in Japan, the relationship between the TyG Index and carotid plaque is non-linear. When the TyG Index is less than 9.06, it is associated with carotid plaque.
Introduction:
Epidemiological reports indicate that the global prevalence of carotid plaques steadily increase and occupy about 21.1% in 2020, which is a growing concern worldwide. 1 The plaque formation indicates later stages of atherosclerosis. Once the carotid plaque is dislodged, it will lead to ischaemic stroke. 2–4 Atherosclerosis is currently considered to be a process of chronic inflammation that can lead to endothelial damage, atherosclerosis formation and vascular obstruction. 5 The development is a continuous dynamic…
