Insights
Coronary artery bypass graft surgery (CABG) showed better 30-day survival than percutaneous coronary intervention (PCI) for patients with left main coronary artery disease and cardiogenic shock. Further research is needed on current PCI strategies for this critical patient group.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- The optimal revascularization strategy for patients experiencing cardiogenic shock due to left main coronary artery disease remains unclear.
- This study addresses the comparative effectiveness of bypass surgery versus percutaneous coronary intervention (PCI) in this high-risk population.
Purpose of the Study:
- To compare the 30-day survival rates between coronary artery bypass graft surgery (CABG) and PCI in patients with left main coronary artery disease presenting with cardiogenic shock.
- To identify independent predictors of survival in this patient cohort.
Main Methods:
- Analysis of data from the Should We Emergently Revascularize Occluded Coronaries for Cardiogenic Shock Trial and Registry, including 164 patients with left main disease.
- Individualized revascularization strategy selection by site investigators, comparing 79 CABG cases with 85 PCI cases.
Main Results:
- Coronary artery bypass graft surgery was associated with significantly higher 30-day survival (54%) compared to PCI (14%) in patients with left main coronary artery disease and cardiogenic shock (p
- When the left main artery was the infarct-related artery, 30-day survival was 40% with CABG versus 16% with PCI (p = 0.03).
- Independent predictors of 30-day survival included CABG (hazard ratio, 0.41) and age.
Conclusions:
- Coronary artery bypass graft surgery demonstrated a survival advantage over PCI at 30-day follow-up for patients with left main coronary artery disease and cardiogenic shock.
- The long-term impact and effectiveness of contemporary PCI strategies in this specific subgroup require further investigation.
Background:
The ideal revascularization strategy (bypass surgery versus percutaneous coronary intervention [PCI]) for patients with cardiogenic shock in the setting of left main coronary artery disease is unknown.
Methods:
The Should We Emergently Revascularize Occluded Coronaries for Cardiogenic Shock Trial and Registry included 164 patients with left main disease who underwent revascularization. Although the standard of care at the time and the trial protocol recommended coronary artery bypass graft surgery for patients with left main disease, the revascularization strategy (79 coronary artery bypass graft surgery and 85 PCI) was individualized for each patient by site investigators.
Results:
The median time from myocardial infarction to revascularization was 24.3 hours (interquartile range, 8.7 to 82.5 hours) in the surgical group and 7.4 hours (interquartile range, 3.7 to 19.5 hours) in the PCI group (p < 0.05). Overall 30-day survival with surgery in this setting was 54% (95% confidence interval, 0.43 to 0.69) and was significantly superior to the 14% (95% confidence interval, 0.09 to 0.35) in the PCI group (p
Conclusions:
Coronary artery bypass graft surgery appeared to provide a survival advantage over PCI at 30-day follow-up in patients with left main coronary artery disease. The impact of current PCI strategies on this subgroup is undetermined.
