Lp(a) With CCTA Assessed Parameters and Clinical Outcomes

• Conditions: Coronary Artery Disease

• Registration Number: NCT05323227
• Lead Sponsor: Shanghai Zhongshan Hospital

Brief Summary

Lipoprotein(a) \[Lp(a)\] is a risk factor for cardiovascular events, although the underlying mechanism remains unclear. This study evaluated the relationship between Lp(a) and high-risk attributes (HRA) by coronary computed tomography angiography (CCTA) as well as their prognostic value.
