Small benefit from CABG over PCI for angina relief for some patients

A small benefit was found in relief from angina after CABG than after PCI at 6 and 12 months in patients with three-vessel or left main coronary artery disease, according to a study in the New England Journal of Medicine.   

For the study, patients were assigned to undergo either CABG or PCI with paclitaxel-eluting stents, and were then assessed  at 1, 6, and 12 months with the use of the Seattle Angina Questionnaire and the Medical Outcomes Study 36-Item Short-Form Health Survey. 

The study found that the number of patients who were free from angina was higher in the CABG group than in the PCI group at the 6 and 12 month mark, although the benefit was small.
