NCT04174261

Brief Summary

Remote ischemic preconditioning (RIPC) reduces periprocedural myocardial injury (PMI) after percutaneous coronary intervention (PCI) through various pathways, including an adenosine-triggered pathway. Ticagrelor inhibits adenosine uptake, thus may potentiate the effects of RIPC. This randomized trial tested the hypothesis that ticagrelor potentiates the effect of RIPC and reduces PMI, as assessed by post-procedural troponin release

Outcome Measures

Primary Outcomes (1)

  • deltaTnI

    The primary outcome measure of the study was deltaTnI, defined as the difference between cardiac troponin I (cTnI) levels at 24 hours post-PCI and cTnI levels before the procedure.

    At the time of PCI / 24 hours post-PCI

Secondary Outcomes (3)

  • Peri-procedural MI (type 4a MI)

    24 hours post-PCI

  • Chest pain during PCI: analog 10-point scale

    During the PCI procedure

  • ST-segment deviation during PCI

    During the PCI procedure

Other Outcomes (1)

  • Bleeding

    At the time of PCI / 24 hours post-PCI

Masking Details
Patient randomization in the ticagrelor and the clopidogrel group took place using sealed, opaque envelopes containing a computer-generated randomization scheme. Using a similar procedure, patients were then randomly assigned to RIPC or no RIPC within 1 hour before the procedure.

Intervention Model
FACTORIAL
Model Details: The TRIP study was a randomized, assessor-blind, active comparator-controlled, clinical trial using a 2×2 factorial design, with 1:1 patient allocation to ticagrelor or clopidogrel and within each treatment a 1:1 allocation to RIPC or control.
