Title: Purpose
1SYNTAX SYNergy between percutaneous coronary
intervention with TAXus and cardiac surgery
-
- Purpose
- To compare percutaneous coronary intervention
(PCI) and coronary artery bypass grafting (CABG)
in patients with previously untreated
three-vessel or left main coronary artery
disease, or both. - Reference

TRIAL DESIGN -
- Design
- Prospective, multicenter, multinational,
randomized, all-comers trial. - Patients
- 4337 patients with previously untreated
three-vessel or left main coronary artery disease
(or both) were initially screened. After local
assessment, 3075 patients were included 1800
were randomly assigned to CABG or PCI 1275 were
enrolled in a parallel, nested registry. - Exclusion criteria included being lt21 years old,
having previously had PCI or CABG, and needing
concomitant surgery. -
- Follow-up and primary endpoint
- Patients were followed up at 30 days
post-procedure and at 1, 6, 12, 36 and 60 months
post-allocation. The primary endpoint was a
composite of death from any cause, stroke,
myocardial infarction, or repeat vascularization
by 12 months.TreatmentSurgical techniques
chosen on the basis of local clinical practice.

intervention with TAXus and cardiac surgery -
RESULTS -
- At 12 months, the incidence of the primary
endpoint of major adverse cardiac or
cerebrovascular events was significantly higher
with PCI than with CABG (17.8 vs. 12.4,
respectively relative risk RR, 1.44
p0.002)?. - The rate of repeat revascularization at 12 months
was significantly higher with PCI than with CABG
(13.5 vs. 5.9, respectively RR, 2.29
plt0.001).? - The rate of stroke at 12 months was significantly
lower with PCI than with CABG (0.6 vs. 2.2,
respectively RR, 0.25 p0.003)? - The rate of death from cardiac causes was
significantly greater with PCI than with CABG
(3.7 vs. 2.1, respectively RR, 1.75 p0.05),
and the rate of non-cardiac causes was
non-significantly higher. - Rates of death from any cause or myocardial
infarction, the combined endpoint of death from
any cause, stroke, or myocardial infarction, and
rates of graft occlusion or stent thrombosis were
similar.

6SYNTAX SYNergy between percutaneous coronary
intervention with TAXus and cardiac surgery -
SUMMARY -
-
- At 1 year, in patients with three-vessel or left
main coronary artery disease, or both - CABG, compared with PCI, is associated with a
lower rate of major adverse cardiac or
cerebrovascular events - Rates of death and myocardial infarction were
similar between CABG and PCI - The rate of stroke was increased with CABG,
whereas the rate of repeat revascularization was
increased with PCI - The investigators concluded that CABG should
remain the standard of care.
