Atrial fibrillation is the most common heart rhythm disorder after cardiac surgery. In previous studies it has been associated with prolonged hospitalization, increased costs and mortality. This study aimed to determine the prevalence of postoperative atrial fibrillation in cardiac surgery and its impact on the hospitalization period. Medical records of consecutive patients undergoing cardiac surgery (coronary artery bypass graft, valvular, or both) between January 2006 and November 2008 were included and retrospectively analyzed. Primary outcome was the presence of postoperative atrial fibrillation. The sample was divided into two groups, with and without atrial fibrillation in the postoperative. The clinical variables and length of hospital stay were compared between both groups. A total of 172 patients underwent surgery in this period. Seven patients were excluded from analysis due to lack of data. The mean age was 64.2 +/- 9.5 years, and they were predominantly male. Atrial fibrillation was the most common complication (23.6%). The average length hospital stay was 6.7 +/- 4.6 days. There were no significant differences between both groups, with atrial fibrillation (7.5 +/- 4.1 days), and without (6.5 +/- 4.7 days), p = 0.21. The presence of atrial fibrillation did not prolong hospitalization. Probably, such strategy of prevention would not be cost-effective.
心房颤动是心脏手术后最常见的心律失常。在以往的研究中，它与住院时间延长、费用增加和死亡率上升有关。本研究旨在确定心脏手术术后心房颤动的患病率及其对住院时间的影响。纳入了2006年1月至2008年11月期间连续接受心脏手术（冠状动脉搭桥术、瓣膜手术或两者皆有）患者的病历，并进行回顾性分析。主要结局是术后心房颤动的存在情况。样本分为两组，术后有和无心房颤动。比较两组的临床变量和住院时间。在此期间共有172例患者接受手术。7例患者因数据缺失被排除在分析之外。平均年龄为64.2±9.5岁，且以男性为主。心房颤动是最常见的并发症（23.6%）。平均住院时间为6.7±4.6天。有房颤组（7.5±4.1天）和无房颤组（6.5±4.7天）之间无显著差异，p = 0.21。心房颤动的存在并未延长住院时间。可能，这样的预防策略不具有成本效益。
