BACKGROUND: Elevated levels of uric acid in serum (SUA) or plasma (PUA) are increasingly related to cardiovascular disease. It is unclear whether they are independent risk factors or simply markers, reflecting association with other traditional risk factors. METHODS: We retrospectively assessed results of a lipid profile, including total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, total cholesterol to HDL-C ratio (TC/HDL-C), the atherogenic index of plasma (AIP), and lipoprotein(a) (Lp[a]), in a large cohort of unselected adult outpatients. RESULTS: Hyperuricemic men displayed significantly increased values of triglycerides and AIP when compared with men with normal PUA levels. In hyperuricemic women, significant differences were observed for HDL-C, triglycerides, TC/HDL-C, and AIP compared with women with normal PUA levels. The percentage of patients with unfavorable values was statistically higher for triglycerides and AIP in hyperuricemic men; for HDL-C, triglycerides, TC/HDL-C, and AIP in hyperuricemic women. In multivariable linear regression analysis triglycerides, AIP, and TC/HDL-C were independently associated with PUA in women, whereas no significant association was observed in men. CONCLUSION: PUA measurement might be advisable in patients to identify those at increased risk of cardiovascular disease (CVD) who might benefit from further triage and intervention.
背景:血清尿酸(SUA)或血浆尿酸(PUA)水平升高与心血管疾病的关系日益密切。目前尚不清楚其是独立的危险因素,还是仅仅是反映与其他传统危险因素相关的标志物。
方法:我们回顾性评估了一个大型非选择性成年门诊患者队列的血脂谱结果,包括总胆固醇、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、甘油三酯、总胆固醇与高密度脂蛋白胆固醇的比值(TC/HDL-C)、血浆致动脉粥样硬化指数(AIP)和脂蛋白(a)(Lp[a])。
结果:与 PUA 水平正常的男性相比,高尿酸血症男性的甘油三酯和 AIP 值显著升高。与 PUA 水平正常的女性相比,高尿酸血症女性的 HDL-C、甘油三酯、TC/HDL-C 和 AIP 值存在显著差异。与 PUA 水平正常的女性相比,高尿酸血症男性的甘油三酯和 AIP 患者的不良值比例更高;与 PUA 水平正常的女性相比,高尿酸血症女性的 HDL-C、甘油三酯、TC/HDL-C 和 AIP 患者的不良值比例更高。多元线性回归分析显示,女性的 PUA 与甘油三酯、AIP 和 TC/HDL-C 独立相关,而男性则无显著相关性。
结论:在患者中测量 PUA 可能有助于识别心血管疾病(CVD)风险增加的患者,这些患者可能受益于进一步的分类和干预。
