NCT04310995

Brief Summary

The Pilot study will be a single-center, randomized, open-label, active-controlled trial. After CABG surgery using Radial Artery Grafts (RA-CABG) and signing the informed consent, all patients will be screened according to the inclusion and exclusion criteria. Estimated 150 patients will be enrolled and randomized by ratio 1:1:1 to receive either Nicorandil (5mg tid po) or Diltiazem (180mg qd po) or Isosorbide Mononitrate (50mg qd po). Follow-up visits will be conducted at Week 1, 4, 12, and 24 after surgery. The last evaluation of study endpoints and other adverse events will be at Week 24. The pilot study is designed to explore the angiography outcomes of grafts and cardiovascular outcomes of patients, as well as safety outcomes among different anti-spastic regimens after RA-CABG.

Outcome Measures

Primary Outcomes (2)

  • the rate of RA graft failure at Week 1

    CCTA or CAG will be used to evaluate the RA graft outcome at Week 1 after RA-CABG. The definition of RA-graft outcomes will refer to the modified Fitzgibbon classification criteria. When RA-graft outcome conform to the Grade B, O or S, the result will be judged as the graft failure.

    at Week 1

  • the rate of RA graft failure at Week 24

    CCTA or CAG will be used to evaluate the RA graft outcome at at Week 24 after RA-CABG. The definition of RA-graft outcomes will refer to the modified Fitzgibbon classification criteria. When RA-graft outcome conform to the Grade B, O or S, the result will be judged as the graft failure.

    at Week 24

Secondary Outcomes (5)

  • the time to first Major Adverse Cardiovascular Events (MACE)

    within 24 weeks

  • the proportion of subjects with angina recurrence

    within 24 weeks

  • the proportion of subjects with at least one hypotension occurrence

    within 24 weeks

  • the proportion of subjects with ACEI/ARB/ARNI withdrawal

    within 24 weeks

  • the proportion of subjects with serious adverse events (SAEs) and concerned adverse events (AEs)

    within 24 weeks
