Atherosclerosis is an important pathologic cause of cardiovascular disease (CVD) and a leading cause of morbidity and mortality worldwide. Menopause involves changes in hormonal status that are associated with an increased risk of developing CVD. The atherogenic index of plasma (AIP) has been used as a predictor of atherosclerosis. Atherosclerosis might also be assessed using a surrogate marker, the carotid artery wall intima media thickness (CIMT).
To assess the usefulness of AIP compared with traditional anthropometrics for predicting CIMT in perimenopausal and menopausal women.
This is a cross-sectional study involving perimenopausal and menopausal women voluntarily recruited. Lipid profiles, including total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were assessed and AIP was calculated [log (TG/HDL-C)]. The anthropometric parameters of body mass index (BMI), waist circumference (WC), hip circumference (HC), and waist-hip ratio (WHR) were assessed. Pearson Chi-square for AIP and anthropometric parameters relationship to CIMT in perimenopausal and menopausal women.
One hundred fourteen perimenopausal and menopausal women were included in this study. The novel atherosclerotic index of AIP and the anthropometric parameter of BMI were correlated with CIMT in both groups (p<0.01). There was no difference in AIP between perimenopausal and menopausal women. Neither WC nor WHR were different between the two groups. CIMT was significantly thicker in the menopausal compared with the perimenopausal group [0.78±0.16 vs. 0.64±0.09, respectively (p<0.01)].
AIP can add significant value when assessing the risk of developing the atherosclerosis marker of thickened CIMT in perimenopausal and menopausal women. A high AIP in menopause may indicate a higher risk of cardiovascular events in spite of no difference in common CVD risk factors such as lipid profile parameters.
动脉粥样硬化是心血管疾病(CVD)的重要病理原因,也是全球发病和死亡的主要原因。绝经涉及激素状态的变化,这与患CVD风险增加相关。血浆致动脉粥样硬化指数(AIP)已被用作动脉粥样硬化的预测指标。动脉粥样硬化也可使用替代标志物颈动脉壁内膜中层厚度(CIMT)进行评估。
评估AIP与传统人体测量指标相比,在预测围绝经期和绝经后女性CIMT方面的效用。
这是一项横断面研究,纳入了自愿招募的围绝经期和绝经后女性。评估血脂谱,包括总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C),并计算AIP[log(TG/HDL-C)]。评估体重指数(BMI)、腰围(WC)、臀围(HC)和腰臀比(WHR)等人体测量参数。采用Pearson卡方检验分析围绝经期和绝经后女性中AIP及人体测量参数与CIMT的关系。
本研究纳入了114名围绝经期和绝经后女性。两组中,新型动脉粥样硬化指标AIP和人体测量参数BMI均与CIMT相关(p<0.01)。围绝经期和绝经后女性的AIP无差异。两组间WC和WHR均无差异。与围绝经期组相比,绝经后组的CIMT明显更厚[分别为0.78±0.16和0.64±0.09,(p<0.01)]。
在评估围绝经期和绝经后女性发生CIMT增厚这一动脉粥样硬化标志物的风险时,AIP可增加显著价值。尽管在血脂谱参数等常见CVD危险因素方面无差异,但绝经后AIP升高可能表明心血管事件风险更高。
