摘要:

目的 分析脂蛋白(a)[Lp(a)]质量浓度在就诊和体检人群中的分布及其异常率变化趋势。方法 收集2005年11月—2024年12月复旦大学附属中山医院1 540 949例就诊者和体检者Lp(a)质量浓度数据。对数据进行清洗后,采用Mann-Kendall趋势检验法分析Lp(a)质量浓度的分布和>300 mg·L-1的异常率。筛选出Lp(a)检测次数≥2次的受检者,统计首末次检测结果的变化。结果 2005年—2024年,Lp(a)质量浓度第50百分位数(P50)相对稳定,2005年为111.0 mg·L-1,2024年为110.2 mg·L-1;第25百分位数(P25)从56.0 mg·L-1上升至62.5 mg·L-1,第75百分位数(P75)从226.5 mg·L-1上升至248.7 mg·L-1。Lp(a)异常率总体略有上升,且女性高于男性,80岁以上人群异常率最高。受检者首末次Lp(a)变化程度不大,2次Lp(a)质量浓度均<300 mg·L-1和≥300 mg·L-1者分别占分别为95.5%和85.8%。结论 2005—2024年,复旦大学附属中山医院受检人群Lp(a)质量浓度P50保持稳定,P25P75和异常率均有上升趋势,其中女性Lp(a)质量浓度上升趋势较男性更为明显。值得注意的是,40~59岁男性、女性Lp(a)异常率呈显著上升趋势,早期连续监测Lp(a)对心血管疾病的发现、预防和治疗具有重要意义。

Abstract:

Objective To investigate the distribution of lipoprotein(a) [Lp(a)] concentration and the trend of abnormal rate changes. Methods The Lp(a) concentration data of 1 540 949 cases who visited or underwent examinations at Zhongshan Hospital of Fudan University from November 2005 to December 2024 were collected. After datum cleaning,Mann-Kendall trend test was used to analyze the distribution of Lp(a) concentration and the abnormal rate >300 mg·L-1. The individuals with ≥2 Lp(a) concentration tests was selected,and the changes in the first and last results were analyzed. Results The 50th percentile(P50) of Lp(a) concentration was relatively stable,being 111.0 mg·L-1 in 2005 and 110.2 mg·L-1 in 2024. While the 25th percentile(P25) increased from 56.0 mg·L-1 to 62.5 mg·L-1,and the 75th percentile(P75) increased from 226.5 mg·L-1 to 248.7 mg·L-1. The overall abnormal rate of Lp(a) slightly increased,and it was higher in females than in males. The abnormal rate is the highest among population over 80 years old. The changes in Lp(a) between the first and last tests in the population were not significant,and the proportions of Lp(a) concentrations <300 mg·L-1 and ≥300 mg·L-1 in the 2 tests were 95.5% and 85.8%,respectively. Conclusions From 2005 to 2024,the P50 of Lp(a) concentration in the tested population from zhongshan Hospital of Fudan University remained stable,while the P25P75 and abnormal rate showed an upward trend. Among them,the increase in Lp(a) concentration in females was more significant than that in males. It is notable that the abnormal rate of Lp(a) in males and females aged 40-59 years showed a significant upward trend,and continuous early monitoring of Lp(a) is of significance for the discovery,prevention and treatment of cardiovascular diseases.
