A Summary of Several Studies on Lp(a) Cutoff Values in Chinese Populations

Population	Sample Size	Primary Endpoint	High Lp(a) vs Low Lp(a)	Main Conclusions	Lp(a) Cutoff
Healthy population receiving routine physical checkup16	9,238	Myocardial infarction	Lp(a) <16.7 mg/dL vs Lp(a) ≥16.7 mg/dL	High Lp(a) is significantly correlated with myocardial infarction	17 mg/dL
Patients with a history of CAD37	7,562	Recurrent CVE	The first tertile of Lp(a) levels (<8.88 mg/dL) vs the third tertile (≥26.45 mg/dL)	High Lp(a) is independently correlated with the risk of recurrent CVE	26.45 mg/dL
Stable CAD patients with a history of PCI43	4,078	CVE	Lp(a) <15 mg/dL vs Lp(a) ≥30 mg/dL	High Lp(a) is correlated with CVE	30 mg/dL
Patients with a history of MI45	3,864	CVE	The first quartile of Lp(a) levels (<8.19 mg/dL) vs the third quartile (18.84-41.43 mg/dL)	The cumulative rates of CVEs and cardiac mortality were significantly higher in patients with high Lp(a) levels	18.84 mg/dL
Population aged >40 y and receiving routine physical check-up26	8,500	Stroke	Lp(a) <26 mg/dL vs Lp(a) ≥26 mg/dL	High Lp(a) is significantly correlated with stroke	26 mg/dL
Patients with ischemic stroke (ischemic and hemorrhagic)38	2,149	Stroke	The first quartile of Lp(a) levels (<4.6 mg/dL) vs the fourth quartile (≥23.2 mg/dL)	High Lp(a) is positively correlated with ischemic and hemorrhagic ischemic stroke	23.2 mg/L

CVE = cardiovascular event; MI = myocardial infarction; PCI = percutaneous coronary intervention; other abbreviations as in Table 1.
