Study on Risk Factors and Prognostic Value of Non-target Lesion Progression in Patients With Coronary Artery Disease

Running, not enrolling

Conditions studied: Coronary Artery Disease (CAD)

In brief

The goal of this observational study is to explore the risk factors and prognostic value of non-target coronary lesion progression in patients aged 18-80 years with established coronary artery disease who are scheduled for repeat coronary angiography. The main questions it aims to answer are: What clinical, inflammatory and metabolic factors are independently associated with the progression of untreated non-target lesions after percutaneous coronary intervention? Does the initial interventional strategy (drug-eluting stent vs. drug-coated balloon) influence the long-term progression of non-target coronary lesions and subsequent clinical outcomes? Researchers will compare participants treated with drug-eluting stents (DES) and those treated with drug-coated balloons (DCB) at their prior index procedure to see if different local interventional modalities lead to differences in non-target lesion progression and major adverse cardiovascular events during follow-up. Participants will: Undergo clinically indicated repeat coronary angiography, with offline quantitative coronary angiography (QCA) analysis of all coronary segments Provide baseline clinical data, medical history and blood samples for inflammatory and metabolic biomarker testing Complete 3 years of regular clinical follow-up to track lesion evolution and cardiovascular endpoints

You may qualify if…

• To be eligible for enrollment in this study, participants must meet all of the following criteria:
• Aged 18 to 80 years, regardless of gender, with full decision-making capacity; Previously diagnosed with coronary artery disease (coronary artery diameter stenosis ≥ 50%) by coronary angiography, and scheduled to undergo repeat coronary angiography; Able to provide written informed consent. Exclusion Criteria
• Participants will be excluded from the study if they meet any of the following criteria:
• Undergoing coronary artery bypass grafting (CABG) during the index hospitalization; Poor angiographic image quality (vessel overlap, inadequate opacification) that precludes quantitative coronary angiography (QCA) or Angio FFR analysis; Concomitant severe valvular heart disease, cardiomyopathy, or active infection.
