Insights
For chronic coronary syndrome patients without left main disease, physiology-guided PCI and CABG offer better outcomes than angiography-guided PCI. Coronary artery bypass grafting significantly reduces myocardial infarction and death but increases stroke risk.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Chronic Coronary Syndrome (CCS) management without left main (LM) disease or reduced left ventricle ejection fraction (LVEF) may depend on revascularization strategy.
- Evaluating optimal revascularization strategies is crucial for patient prognosis.
Purpose of the Study:
- To compare the effectiveness of different myocardial revascularization strategies in patients with CCS without LM disease or reduced LVEF.
- To assess outcomes associated with angiography-guided PCI, physiology-guided PCI, and CABG versus medical therapy.
Main Methods:
- Network meta-analysis of 18 randomized controlled trials.
- Inclusion of patients with CCS, excluding those with LM disease or reduced LVEF.
- Comparison of angiography-guided PCI, physiology-guided PCI, and CABG.
Main Results:
- All revascularization strategies reduced the primary endpoint compared to medical therapy.
- Physiology-guided PCI and CABG showed greater reductions than angiography-guided PCI.
- CABG was associated with reduced myocardial infarction, cardiovascular death, and all-cause death, but increased stroke risk.
Conclusions:
- Physiology-guided PCI and CABG yield better outcomes than angiography-guided PCI in CCS patients without LM disease or reduced LVEF.
- CABG is the only strategy reducing myocardial infarction and death rates, albeit with a higher stroke risk.
Background:
The impact of myocardial revascularization on outcomes and prognosis in patients with chronic coronary syndrome (CCS) without left main (LM) disease or reduced left ventricle ejection fraction (LVEF) may be influenced by the revascularization strategy adopted.
Methods:
We performed a network meta-analysis including 18 randomized controlled trials comparing different revascularization strategies, including angiography-guided percutaneous coronary intervention (PCI), physiology-guided PCI and coronary artery bypass graft (CABG), in patients with CCS without LM disease or reduced LVEF.
Results:
Compared with medical therapy, all revascularization strategies were associated with a reduction of the primary endpoint, as defined in each trial, the extent of which was modest with angiography-guided PCI (IRR 0.86, 95% CI 0.75-0.99) and greater with physiology-guided PCI (IRR 0.60, 95% CI 0.47-0.77) and CABG (IRR 0.58, 95% CI 0.48-0.70). Moreover, angiography-guided PCI was associated with an increase of the primary endpoint compared to physiology-guided PCI (IRR 1.43, 95% CI 1.14-1.79) and CABG (IRR 1.49, 95% CI 1.27-1.74). CABG was the only strategy associated with reduced myocardial infarction (IRR 0.68, 95% CI 0.52-0.90), cardiovascular death (IRR 0.76, 95% CI 0.64-0.89), and all-cause death (IRR 0.87, 95% CI 0.77-0.99), but increased stroke (IRR 1.69, 95% CI 1.04-2.76).
Conclusions:
In CCS patients without LM disease or reduced LVEF, physiology-guided PCI and CABG are associated with better outcomes than angiography-guided PCI. Compared with medical therapy, CABG is the only revascularization strategy associated with a reduction of myocardial infarction and death rates, at the cost of higher risk of stroke.
