"This study has been conducted to compare one-year survival rate of patients who underwent coronary artery bypass surgery (CABG) vs. percutaneous coronary intervention (PCI) in general as well as considering the number of diseased coronary vessels. In this retrospective study, we reviewed the medical records of patients who underwent CABG (484 cases) or PCI (292 cases) at out university heart center from 2009 to 2012. The mortality and survival was compared between the two studied groups based on left ventricular function and number of diseased coronary vessels. Twenty-seven patients (5.57%) died in CABG group which was significantly higher than in PCI group (8 cases, 2.73%); P= 0.04. However, no significant difference was observed regarding mortality between CABG and PCI groups in one- diseased vessel (5.15% vs. 2.22%, P= 0.28), two- diseased vessel (6.12% vs. 3.57%, P= 0.41), and three-vessel disease (5.41% vs.0, P= 0.4). Although PCI was associated with a better one-year survival rate compared to CABG, but number of the diseased coronary vessels did not affect survival rate significantly."
