Revascularization options for adults with multivessel coronary disease and non-ST-elevation ACS

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized interventional trial compares contemporary percutaneous coronary intervention (PCI) using drug-eluting stents with coronary artery bypass grafting (CABG) in adults presenting with non-ST-elevation acute coronary syndrome (NSTE-ACS) and multivessel coronary disease, including possible left main involvement. Eligible patients present within an urgent window (typically within 72 hours) and have angiographic multivessel disease or left main narrowing with anatomical limits such as a SYNTAX score below predefined thresholds. The protocol allows contemporary invasive strategies including culprit-lesion PCI with possible staged complete PCI versus surgical revascularization, with follow-up for early procedural outcomes and longer-term event-free survival. The trial is conducted at multiple Polish cardiac centers affiliated with the American Heart of Poland and collaborating universities.

Why it matters

Who can join: the full rules

Inclusion Criteria:

Subjects must meet ALL of the inclusion criteria to be considered for the trial. If ANY of the exclusion criteria are met, the subject is excluded from the trial and cannot be randomized.

* Age over 18 years,
* Written patient consent,
* Acute Coronary Syndrome without ST-segment elevation of high, intermediate and low risk, including NSTEMI and unstable angina requiring urgent (within 72 hours) invasive strategy,
* Qualification for invasive treatment,
* Multivessel coronary disease, defined as angiographic narrowing \>50%DS on investigator's visual assessment in at least two major coronary artery territories (RCA, LAD, LCX), including involvement of the proximal segment of the left anterior descending artery or three-vessel disease with a Syntax Score \< 33. Intermediate lesions (40-70%) will need to be assessed with either FFR, iFR, or VFFR). Patient may have left main coronary artery disease, defined as narrowing \>50%DS (but this is not obligatory). For borderline changes, IVUS (MLA \<6 mm2 or iFR=\<0,90 or FFR=\<0,80, with an anatomic Syntax Score \<33 will be decisive,
* Feasibility of complete revascularization on both the CABG and PCI sides,
* Consent within the Heart Team for both CABG by the cardiothoracic surgeon and PCI by the interventional cardiologist.

Exclusion Criteria:

* Age under 18 years,
* ST-segment elevation myocardial infarction (STEMI) or new left bundle branch block (LBBB),
* Stable coronary syndrome,
* Single- or two-vessel coronary disease without involvement of the proximal LAD, defined as narrowing above 50%DS,
* Qualification for conservative treatment,
* Anticipated surgery other than CABG due to severe valvular defect or other structural defect, particularly moderate or severe mitral regurgitation,
* Need for immediate coronary angioplasty treatment,
* Syntax Score equal or above 33 (\>=33),
* Contraindications to short-term and long-term antiplatelet therapy,
* Acute heart failure in class IV (cardiogenic shock),
* Previous CABG procedure,
* Previous PCI procedure within the last 6 months,
* Ischemic or hemorrhagic stroke within 6 months prior to inclusion,
* End-stage chronic kidney disease on dialysis,
* Pregnancy or intention to become pregnant (women of child bearing age must have a recent negative pregnancy test prior to randomization),
* Non cardiac co-morbidities with life expectancy less than 3 years,
* Participation in other clinical trial that have not reached their primary endpoint.
