摘要:

目的 在中国一般人群中探究血脂与左心室肥厚之间的联系。
方法 为了探讨血脂与左心室肥厚之间的关系,我们开展了一项回顾性观察研究,纳入了以下血脂指标:甘油三酯、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、非高密度脂蛋白胆固醇、载脂蛋白A-I、载脂蛋白B、脂蛋白(a)和3种复合血脂指标。首先,我们构建了一项横断面研究,其中包含两个人群,分别来自于北京市和全国其他10个省份。受试者为2009年至2018年期间在中国不同健康管理中心进行体检的成年人,共计309,400人。然后,我们将7475名进行过多次体检且最初没有左心室肥厚的受试者组建了一个纵向队列,以分析各血脂指标与新发左心室肥厚之间的关联。超声心动图被用于诊断左心室肥厚(左心室肥厚为室间隔或左心室后壁的舒张末期厚度>11mm)。在横断面研究中采用Logistic回归模型。在队列研究中采用Cox比例风险回归模型和限制性立方样条Cox比例风险回归模型。
结果 横断面研究显示:与对应血脂指标水平处于人群最低三分之一的受试者相比,甘油三酯(OR:1.250, 95%CI:1.060~1.474)、高密度脂蛋白胆固醇(OR:0.780,95%CI:0.662~0.918)和脂蛋白(a)(OR:1.311,95%CI:1.115~1.541)水平处于最高三分之一的受试者的左心室肥厚风险增加。队列研究显示:相比于基线时对应血脂指标处于最低三分之一的受试者,甘油三酯(HR:3.277,95%CI:1.720~6.244)、高密度脂蛋白胆固醇(HR:0.516,95%CI:0.283~0.940),非高密度脂蛋白胆固醇(HR:2.309,95%CI:1.296~4.112)及载脂蛋白B(HR:2.244,95%CI:1.251~4.032)水平处于最高三分之一的受试者发生左心室肥厚的风险增加。在向前逐步回归的Cox模型中,甘油三酯是进入最终模型的唯一脂质标志物。
结论 脂质水平,尤其是甘油三酯,与左心室肥厚有关。管控甘油三酯水平有可能成为阻止心室重塑的一种新途径,值得进一步深入研究。

Abstract:

Objective To explore the association between lipid profiles and left ventricular hypertrophy in a Chinese general population.
Methods We conducted a retrospective observational study to investigate the relationship between lipid markers [including triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL-cholesterol, apolipoprotein A-I, apolipoprotein B, lipoprotein[a], and composite lipid profiles] and left ventricular hypertrophy. A total of 309,400 participants of two populations (one from Beijing and another from nationwide) who underwent physical examinations at different health management centers between 2009 and 2018 in China were included in the cross-sectional study. 7,475 participants who had multiple physical examinations and initially did not have left ventricular hypertrophy constituted a longitudinal cohort to analyze the association between lipid markers and the new-onset of left ventricular hypertrophy. Left ventricular hypertrophy was measured by echocardiography and defined as an end-diastolic thickness of the interventricular septum or left ventricle posterior wall > 11 mm. The Logistic regression model was used in the cross-sectional study. Coxmodel and Coxmodel with restricted cubic splines were used in the longitudinal cohort.
Results In the cross-sectional study, for participants in the highest tertile of each lipid marker compared to the respective lowest, triglycerides [odds ratio (OR): 1.250, 95%CI: 1.060 to 1.474], HDL-cholesterol (OR: 0.780, 95%CI: 0.662 to 0.918), and lipoprotein(a) (OR: 1.311, 95%CI: 1.115 to 1.541) had an association with left ventricular hypertrophy. In the longitudinal cohort, for participants in the highest tertile of each lipid marker at the baseline compared to the respective lowest, triglycerides [hazard ratio (HR): 3.277, 95%CI: 1.720 to 6.244], HDL-cholesterol (HR: 0.516, 95%CI: 0.283 to 0.940), non-HDL-cholesterol (HR: 2.309, 95%CI: 1.296 to 4.112), apolipoprotein B (HR: 2.244, 95%CI: 1.251 to 4.032) showed an association with new-onset left ventricular hypertrophy. In the Coxmodel with forward stepwise selection, triglycerides were the only lipid markers entered into the final model.
Conclusion Lipids levels, especially triglycerides, are associated with left ventricular hypertrophy. Controlling triglycerides level potentiate to be a strategy in harnessing cardiac remodeling but deserve to be further investigated.

Key words: left ventricular hypertrophy, lipid, triglycerides, apolipoprotein
