About this trial
This study aims to investigate whether TET2-associated clonal hematopoiesis of indeterminate potential (TET2-CHIP) can serve as a biomarker to guide precision use of colchicine in a population of clinically stable post-ACS patients receiving standard of care (SoC) therapy. Specifically, we will evaluate whether TET2-CHIP status predicts a differential response to colchicine. As a pilot study, it also aims to provide detailed data supporting design of further trial, such as sample size calculating, endpoint optimizing, etc.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age 40-85 years;
During the index hospitalization, patients underwent either PCI or diagnostic coronary angiography alone,
At least one non-culprit coronary lesion with 30%-70% diameter stenosis by visual estimation on coronary angiography,
Clinically stable throughout the screening period,
Disqualifiers
Prior coronary artery bypass grafting (CABG) before documented ACS;
Other clinically significant cardiovascular diseases, including moderate-to-severe valvular heart disease (moderate or severe), heart failure (NYHA class III-IV), or atrial fibrillation;
Non-culprit coronary anatomy (e.g., marked tortuosity, bifurcation lesions, or small vessels <1.5 mm in diameter) deemed to preclude plaque assessment by CCTA;
Planned PCI or CABG;
