Coronary-artery bypass better than stent implantation

For patients with two or more diseased coronary arteries, CABG is associated with higher adjusted rates of long-term survival than stenting.

Researchers compared outcomes for coronary-artery bypass grafting ( CABG ) and percutaneous coronary intervention ( PCI ).

They used New York's cardiac registries to identify 37,212 patients with multivessel disease who underwent CABG and 22,102 patients with multivessel disease who underwent PCI from January 1, 1997, to December 31, 2000.

The death rate for patients with two-vessel disease was 24 percent lower with bypass surgery and 36 percent for patients with three-vessel disease.
The three-year rates of revascularization were considerably higher in the stenting group than in the CABG group ( 7.8 percent versus 0.3 percent for subsequent CABG and 27.3 percent vs. 4.6 percent for subsequent PCI ).
