Brief Summary
The goal of this exploratory clinical trial is to investigate the proteomic changes induced by low-dose colchicine anti-inflammatory therapy in coronary heart disease (CHD) patients, with the aim of identifying novel biomarkers and therapeutic targets. The main questions it aims to answer are:
- Whether short-term colchicine treatment induces significant changes in the plasma proteomic profile of post-PCI CHD patients with residual inflammation.
- Which specific proteins or pathways are dynamically modulated by colchicine, indicating potential mechanisms of action and drug targets.
- How the proteomic expression profiles differ between patients treated with colchicine and matched controls after one month. Participants, recruited based on a prior RCT framework, will be post-PCI CHD patients with elevated inflammation (hs-CRP ≥ 2 mg/L). A total of 176 participants will be enrolled: 88 in the trial group (colchicine 0.5 mg/day) and 88 in the matched control group (no intervention). All participants will complete a one-month follow-up. Peripheral blood samples will be collected at baseline and at the one-month visit for high-throughput proteomic analysis using Olink technology.

Outcome Measures
Primary Outcomes (2)
Differentially Expressed Proteins
Using high-throughput mass spectrometry techniques (such as Olink, SOMAscan , LC-MS/MS or NULISA), the identification and quantification of differentially expressed proteins in the blood (plasma/serum) samples of patients in the colchicine treatment group and the placebo control group were compared at baseline and after treatment.
From randomization to occurence of first event, assessed up to one year
Enrichment analysis of inflammatory response pathways (such as NLRP3 inflammasome-related proteins, IL-1β, IL-6, and TNF-α pathways)
Using high-throughput mass spectrometry techniques (such as Olink, SOMAscan , LC-MS/MS, ELISA or MSD), the identification and quantification of differentially expressed proteins in the blood (plasma/serum) samples of patients in the colchicine treatment group and the placebo control group were compared at baseline and after treatment.
From randomization to occurence of first event, assessed up to one year
