NCT05829889

Brief Summary

The primary purpose of the study was to determine whether the 2-year probability of major adverse cardiac events (primary composite outcome) differed significantly between patients who underwent angiography-guided Percutaneous Coronary Intervention(PCI) and those who underwent Fractional Flow Reserve(FFR)-guided PCI in patients with Left Main Coronary Artery disease(LMCA).

Outcome Measures

Primary Outcomes (1)

  • The composite event rate

    Composite event consists of death from any causes, myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest, or repeat revascularization. A composite endpoint is an endpoint that is a combination of multiple clinical endpoints. An event is considered to have occurred if any one of several different events is observed.

  • The event rate of myocardial infarction

  • The event rate of hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest

Eligibility Criteria

Age20 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The subject must be ≥20 years of age with angina and/or evidence of myocardial ischemia.
  • Significant de novo LMCA disease, defined as ≥ 50% diameter stenosis by visual estimation with or without concomitant non-left main major epicardial coronary artery disease, amenable to PCI with drug-eluting stent(DES) implantation.
  • The patient or guardian agrees to the study protocol and the schedule of clinical follow-up, and provides informed, written consent, as approved by the appropriate Institutional Review Board/Ethical Committee of the respective clinical site.

You may not qualify if:

  • left anterior descending coronary artery (LAD) or left circumflex coronary artery (LCx) chronic total occlusion (CTO)
  • Extremely calcified or tortuous vessels precluding FFR measurement.
  • The presence of complex coronary disease anatomy or lesion characteristics or other cardiac condition(s) which leads the participating interventional cardiologist to believe that PCI is not suitable (i.e. the subject should be managed with coronary artery bypass graft or medical therapy alone).
  • Recent ST Elevation Myocardial Infarction(\<7 days prior to randomization).
  • Cardiogenic shock and/or need for mechanical/pharmacologic hemodynamic support.
  • Severe left ventricular dysfunction (ejection fraction \<30%).
  • Requirement for other cardiac surgical procedure (e.g., valve replacement or aorta surgery).
  • Contraindication or inability to take aspirin or P2Y12 inhibitors (clopidogrel, ticagrelor, or clopidogrel).
  • Prior PCI of the left main trunk.
  • Prior coronary artery bypass graft surgery.
  • Subjects requiring or who may require additional surgery (cardiac or noncardiac) within 1 year.
  • End-stage renal disease requiring renal replacement therapy.
  • Liver cirrhosis.
  • Pregnant and/or lactating women.
  • Concurrent medical condition with a limited life expectancy of less than 2 years.
  • +4 more criteria
