About this trial

This study is aimed at making a comparison of the safety and efficacy of standard drug therapy (control group), standard drugs combined with lose-dose colchicine therapy (colchicine group) and standard drug combined with prednisone therapy (prednisone group) in patients with coronary heart disease who suffered from recurrent In-stent restenosis (RISR).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

CAD patients over 18 years old;

At least one coronary artery lesion meets the RISR criteria: target lesion ≥ 2 ISRs (stenosis of lumen diameter within the stent segment and within 5mm near and far of the stent ≥ 50%);

Intended intervention treatment for RISR lesions;

Acceptable for standard secondary prevention drug therapy for coronary heart disease, including dual antiplatelet therapy (DAPT) and statins;

Disqualifiers

The previous interventional treatment situation is unknown;

The mechanism of intracavitary imaging to clarify ISR is operator-related (poor stent adhesion, incomplete dilation, and stent fracture);

Clearly diagnose vascular inflammatory diseases or connective tissue diseases (including arteritis, Behcet's disease, systemic lupus erythematosus, etc.) involving the coronary artery;

Immunosuppressive drugs, including glucocorticoids, have been used in the past 30 days;

Trial design

Design model

Parallel

Treatments tested in this trial

  • Colchicine

    Drug

    Add 0.5mg QD orally and start using it within 48 hours after intervention.

  • Prednisone

    Drug

    0.5mg/kg QD orally and the dosage was reduced at a rate of 5mg/d per month until 5-10mg/d, maintained for 1 year after PCI.

  • Aspirin

    Drug

    Patients who have re-implanted DES should receive aspirin for at least 1 year after intervention; Patients who have underwent DEB expansion should apply aspirin for at least 3 months after intervention.

  • P2Y12 Receptor Antagonist

    Drug

    Patients who have re-implanted DES should receive 1 P2Y12 receptor antagonist for at least 1 year after intervention; Patients who have underwent DEB expansion should apply the P2Y12 receptor antagonist for at least 3 months after intervention.

  • Lipid-lowering drug

    Drug

    Formulate the lipid-lowering drug regimen with LDL-C\<1.4mmol/L as the target on the basis of moderate intensity or above statins.
