Insights
Updated 5-year outcomes from the NOBLE trial show percutaneous coronary angioplasty is non-inferior to coronary artery bypass grafting for unprotected left main stenosis treatment.
Area of Science:
- Cardiovascular medicine
- Interventional cardiology
- Cardiac surgery
Background:
- Unprotected left main coronary artery stenosis is a high-risk condition.
- Percutaneous coronary angioplasty (PCI) and coronary artery bypass grafting (CABG) are primary treatment options.
- The NOBLE trial aimed to compare long-term outcomes of PCI versus CABG.
Purpose of the Study:
- To compare the 5-year efficacy and safety of PCI versus CABG in patients with unprotected left main coronary artery stenosis.
- To provide updated long-term data for clinical decision-making.
Main Methods:
- Randomized, multicenter, non-inferiority trial.
- Included patients with unprotected left main coronary artery stenosis.
- Assessed outcomes at 5 years post-intervention.
Main Results:
- The primary composite endpoint occurred in 22.0% of PCI patients and 17.8% of CABG patients (hazard ratio, 1.27; 95% CI, 0.92-1.76).
- PCI was found to be non-inferior to CABG.
- No significant differences in rates of death, stroke, or myocardial infarction between groups.
Conclusions:
- Percutaneous coronary angioplasty is a safe and effective alternative to coronary artery bypass grafting for treating unprotected left main coronary artery stenosis at 5 years.
- These findings support PCI as a viable treatment option, offering similar long-term outcomes to CABG.
