Serum Gamma-Glutamyltransferase Level Is Associated with Framingham Risk Score / 中山大学学报(医学科学版)

ABSTRACT

@#【Objective】Serum gamma-glutamyltransferase（GGT）has recently been implicated in the pathogenesis of atherosclerosis and coronary heart disease（CHD）. We aimed to evaluate the association between the serum GGT level and the 10-year risk score for CHD（Framingham Risk Score，FRS）in a Chinese population.【Methods】We conducted a population-based cross-sectional study in 9，544 Guangzhou residents aged 40 years and older. Participants were divided into four quartiles according to their GGT levels：Quartile 1 <15 U/L（n=2 407），Quartile 2 15~19.9 U/L（n=2 302）， Quartile 3 20~28.9 U/L（n=2 442），and Quartile 4 ≥29 U/L（n=2 393）. The multivariate logistic regression analysis was used to assess the incidence of intermediate and high risk of developing CHD at 10 years（FRS≥10%）in relation to each quartile increase of serum GGT level.【Results】The incidence of FRS≥10% increased with elevating serum GGT levels（P for trend<0.001）. Compared with the lowest quartile of serum GGT level ，the adjusted odds ratio in the highest quartile was 1.72（95% confidence interval 1.28 to 2.29）.【Conclusion】Serum GGT level is associated with the FRS for CHD ，and might be used as an adjuvant marker for identifying patients at increased risk of cardiovascular events and early intervention.
