|Abstract:||BACKGROUND: the impact of OSA on new cardiovascular events in patients undergoing coronary artery bypass graft (CABG) surgery is poorly explored.METHODS: Consecutive patients referred for CABG underwent clinical evaluation and standard polysomnography in the preoperative period. CABG surgery data, including percentage of off-pump and on-pump CABG, number of grafts, and intraoperative complications, were collected. the primary end point was major adverse cardiac or cerebrovascular events (MACCEs) (combined events of all-cause death, myocardial infarction, repeated revascularization, and cerebrovascular events). Secondary end points included individual MACCEs, typical angina, and arrhythmias. Patients were evaluated at 30 days (short-term) and up to 6.1 years (long term) aft er CABG.RESULTS: We studied 67 patients (50 men; mean age, 58 +/- 8 years; mean BMI, 28.5 +/- 4.1 kg/m(2)). OSA (apnea-hypopnea index >= 15 events/h) was present in 56% of the population. the patients were followed for a mean of 4.5 years (range, 3.2-6.1 years). No differences were observed in the short-term follow-up. in contrast, MACCE (35% vs 16%, P = .02), new revascularization (19% vs 0%, P = .01), episodes of typical angina (30% vs 7%, P = .02), and atrial fibrillation (22% vs 0%, P = .0068) were more common in patients with than without OSA in the long-term follow-up. OSA was an independent factor associated with the occurrence of MACCE, repeated revascularization, typical angina, and atrial fibrillation in the multivariate analysis.CONCLUSIONS: OSA is independently associated with a higher rate of long-term cardiovascular events aft er CABG and may have prognostic and economic significance in CABG surgery.|
