There are no differences in death or myocardial infarction between patients undergoing PCI compared with CABG. Patients undergoing PCI have to undergo significantly more often a second revascularisation procedure than their surgical counterparts. Note the decrease in repeat revascularisation between patients undergoing only PTCA (Lausanne study, BARI) compared with coronary artery stenting (SIMA, ARTS) by approximately one half.
