Effect of Residual Lipid and Inflammation Risk on Atherosclerotic Plaque Progression Under Intensive Lipid-lowering Therapy in Coronary Heart Disease
Intensive lipid-lowering therapy is a cornerstone treatment for coronary heart disease (CHD). However, coronary plaque progression persists in a subset of patients even under intensive lipid-lowering therapy, which may be associated with residual lipid and inflammatory risks. Current research in this area remains largely confined to post hoc analyses of randomized controlled trials , with a notable scarcity of prospective follow-up cohorts. The investigators propose that establishing a prospective cohort will provide more authentic insights into the associations between residual risk factors and plaque progression. In this project, the investigators aim to establish a well-characterized CHD cohort with comprehensive data collection, good compliance, and an appropriate sample size. By focusing on non-target lesions within the target vessel and utilizing intravascular ultrasound (IVUS), the investigators will investigate the impact of residual lipid and inflammatory risks on plaque progression during intensive lipid-lowering therapy.
• Diagnosed with CAD and PCI was successfully performed.
• Presence of non-target lesions near the target lesion (more than 5mm proximal or distal), with stenosis of 20% to 50% and identifiable anatomical markers (e.g., branches, calcifications, stent edges).
• 18 to 75 years old.
• Written informed consent.
