Outcome Measures

Primary Outcomes (2)

  • culprit-related TVF

    composite of cardiac death, myocardial infarction (MI), stent thrombosis, and clinically-driven target vessel revascularization (TVR) at 2 years after SynergyTM implantation

    2 years after stent implantation

  • nonculprit-related TVF

    composite of cardiac death, MI, and clinically-driven TVR at 2 years

    2 years after stent implantation

Secondary Outcomes (5)

  • each component of primary measures

    2 years after stent implantation

  • all cause death

    2 years after stent implantation

  • repeat revascularization

    2 years after stent implantation

  • stroke

    2 years after stent implantation

  • bleeding

    2 years after stent implantation

Interventions

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Between February 2020 and June 2025, a total of 3,000 patients who performe coronary angiography (± FFR) and have at least one coronary stenosis requiring PCI (as culprit) will be enrolled from 15 centers in South Korea.

You may qualify if:

  • Age 19 years or older
  • Symptomatic angina patients with objective myocardial ischemia
  • Patients with at least one major epicardial coronary artery that requires stent implantation
  • Subject who signs with informed consent form

You may not qualify if:

  • ST-segment elevation MI at admission
  • Patients who underwent coronary artery bypass surgery or heart transplantation
  • Left ventricular ejection fraction \<30%
  • Cardiogenic shock
  • Patients whose life expectancy \<2 years
  • Woman who are breastfeeding, pregnant or planning to become pregnant during study
  • Patients in whom anti-platelets or heparin is contraindicated
  • Left main culprit lesion (angiographic diameter stenosis \>50%)
  • Thrombus-containing lesion
  • In-stent restenosis
  • Side branch lesion
  • Chronic total occlusion
  • Small vessel with reference diameter \<2.5mm
  • Coronary spasm despite administration of nitrate
  • Inability for imaging catheter to pass through tight stenosis, calcification, angulations
  • +2 more criteria
