Abstract

Background: Percutaneous coronary intervention (PCI) has become the first-choice treatment strategy the world over for patients with chronic coronary artery disorders. This study compared the effects of previous PCI procedures on the short-term postoperative results of coronary artery bypass graft surgery (CABG). Methodsː This cross-sectional analytical study recruited 220 patients who underwent CABG in Afshar Hospital in the Iranian city of Yazd between March 2009 and February 2013. The mean postoperative morbidity and mortality rates, the mean postoperative left ventricular ejection fraction (LVEF), the mean hemorrhage volume, the mean serum urea level, and the mean length of stay in the intensive care unit (ICU) were compared between the PCI and non-PCI groups. Results: Among the 220 participants, 147(66.8%) were male and 73(33.2%) were female. The mean age of the study population was 59.41±10.52 years. There was no significant difference in the risk of mortality between the 2 groups (P=0.369). The mean serum urea level was 21.14±6.52 mg/dL in the PCI group and 14.45±1.08 mg/dL in the non-PCI group (P=0.016). The mean postoperative LVEF was 43.19±8.81% in the PCI group and 45.51±8.15% in the non-PCI group (P=0.044). The mean length of stay in the ICU was 3.34±1.23 days in the PCI group and 2.22±0.56 days in the non-PCI group (P<0.001). The mean hemorrhage volume was 1113.01±428.13 mL in the PCI group and 961.42±228.31 mL in the non-PCI group (P=0.027). Conclusion: Previous PCI procedures did not affect the post-CABG mortality rate; however, some postoperative results were worse in the PCI group than in the non-PCI group, which should be considered before the selection of the revascularization method.
