Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT05427370). This is a study registration, not published results. Lead sponsor: Sunnybrook Health Sciences Centre. Recruitment status: RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 754 participants (ESTIMATED). Conditions: Coronary Artery Disease, Heart Failure Systolic. Interventions: PROCEDURE: Revascularization by PCI; PROCEDURE: Revascularization by CABG. Primary outcome measures: The Primary outcome is a Composite of all-cause mortality, stroke, spontaneous myocardial infarction, urgent repeat revascularization or heart failure readmission. , Median follow-up of 5 years.. Brief summary: The Canadian CABG or PCI in Patients With Ischemic Cardiomyopathy (STICH3C) trial is a prospective, unblinded, international multi-center randomized trial of 754 subjects enrolled in approximately 45 centers comparing revascularization by percutaneous coronary intervention (PCI) vs. coronary artery bypass grafting (CABG) in patients with multivessel/left main (LM) coronary artery disease (CAD) and reduced left ventricular ejection fraction (LVEF). The primary objective is to determine whether CABG compared to PCI is associated with a reduction in all-cause death, stroke, spontaneous myocardial infarction (MI), urgent repeat revascularization (RR), or heart failure (HF) readmission over a median follow-up of 5 years in patients with multivessel/LM CAD and ischemic left ventricular dysfunction (iLVSD). Eligible patients are considered by the local Heart Team appropriate and amenable for non-emergent revascularization by both modes of revascularization. The secondary objectives are to describe the early risks of both procedures, and a comprehensive set of patient-reported outcomes longitudinally.
