New-onset postoperative atrial fibrillation (AF) is the most common complication following cardiac surgery and is associated with worse short- and long-term outcomes. There are limited detailed, population-based epidemiological and trends data (timing, duration, number of events, and incidence) available on new-onset AF following coronary artery bypass graft surgery (CABG). The purpose of this NIH-funded study was to rigorously assess the epidemiology AF in 4 high volume cardiac surgery programs.
This large multicenter observational study included 11,239 consecutive patients without pre-operative AF who underwent isolated CABG between 2002 and 2010 at 4 U.S. academic medical centers Data routinely collected for the Society of Thoracic Surgeons (STS) database were augmented with a details on AF events abstracted from medical records.
Table 1 summarizes the patient outcomes following isolated CABG by year, as well as details on the incidence, frequency, timing and duration of new-onset post CABG AF. The STS-risk-adjusted incidence of AF was 33.1% over the 9 years and varied little over time. Unadjusted operative mortality and stroke decreased over time (p<0.001).
Our data suggest that ~1/3 of isolated CABG patients develop new-onset AF, and that incidence has remained steady over time despite recent efforts to reduce it. More effective prophylaxis and management is needed, given the impact post-CABG AF is known to have on short- and long-term outcomes.
