Perioperative myocardial ischaemia (MI) is associated with an increased 30-day mortality in patients undergoing isolated coronary artery bypass grafting (CABG). However, additional information on the role of immediate angiography in the case of suspected perioperative MI and the best treatment strategy would be helpful. There is still a lack of studies focused on types of bypass graft dysfunction.
In this study, we have analysed the main factors associated with perioperative MI after isolated CABG surgery and effects of coronary angiography-based treatment strategy on the patient outcome. We report that the best treatment strategy should be discussed within the heart team to determine the optimal solution for each patient. However, our results demonstrated better clinical outcomes in patients who were treated with urgent percutaneous coronary intervention (PCI).
Urgent angiography allows identification of the various underlying causes of perioperative MI and urgent treatment when this is needed. However, urgent PCI may be associated with improved clinical outcome in patients with early graft failure.Davorin Sef, MD
