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.
