Abstract
Aim
The primary goal of the study was to perform retrospective analysis of fast-track coronary artery bypass grafting at our institute to identify risk factors for prolonged hospital stay. A secondary goal was to identify and compare survival statistics with those published in literature.
Method
We performed a retrospective analysis of patients enrolled in our fast-track coronary artery bypass protocol. There were 709 patients with a mean age of 58.85 ± 8.9 years; 572 were men. The mean EuroSCORE II was 2.02% ± 2.64%. Of these 709 patients, 538 (76%) met the requirements for discharge within 100 hours.
Results
Prolonged ventilation or reintubation, major pulmonary complications, gastrointestinal and neurological complications were the strongest predictors of fast-track failure. Persistent atrial fibrillation, postoperative transient renal impairment, requirement for noninvasive ventilation > 3 times, sternal wound infection, insulin-dependent diabetes mellitus, preoperative intraaortic balloon pump for chest pain or ST changes, preoperative severe left ventricular dysfunction, preoperative severe renal impairment, and peripheral arterial disease were also found to be significant risk factors for fast-track failure. Cumulative survival at 66 months of follow-up was 90.2% ± 0.02%.
Conclusion
The risk factors listed above were associated with fast-track failure. Smoking cessation helps to nullify the factor of chronic obstructive pulmonary disease. Intraoperative elective insertion of a balloon pump does not affect the fast-track protocol. Survival was comparable to that described in the literature.
