Context : Atrial fibrillation (AF) is the most common arrhythmia to occur after cardiac surgery. An exaggerated inflammatory response has been proposed to be one etiological factor.
背景:心房颤动(AF)是心脏外科术后最常见的心律失常。过度的炎症反应被认为是其病因之一。
Objective : To test whether intravenous corticosteroid administration after cardiac surgery prevents AF after cardiac surgery.
目的:研究在心脏外科手术后静脉输注皮质类固醇激素是否能预防术后房颤的发生。
Design, Setting, and Patients : A double-blind, randomized multicenter trial (study enrollment August 2005–June 2006) in 3 university hospitals in Finland of 241 consecutive patients without prior AF or flutter and scheduled to undergo first on-pump coronary artery bypass graft (CABG) surgery, aortic valve replacement, or combined CABG surgery and aortic valve replacement.
设计,地点和患者:这是一项双盲,随机,多中心试验(试验入组2005年8月~2006年7月),地点是在芬兰三家大学医院,连续观察241名患者,既往没有房颤或房扑,计划行常规体外循环下冠状动脉旁路移植术(CABG),主动脉瓣置换术,或者冠状动脉旁路移植+主动脉瓣置换术。
Intervention : Patients were randomized to receive either 100-mg hydrocortisone or matching placebo as follows: the first dose in the evening of the operative day, then 1 dose every 8 hours during the next 3 days. In addition, all patients received oral metoprolol (50-150 mg/d) titrated to heart rate.
干预措施:患者被随机分为接受100mg氢化考的松或匹配安慰剂,给药方法如下:首剂在手术日当天晚上,然后每8小时一次×3天。此外,所有患者均根据心律给与口服美托洛尔(50-150mg/d)。
Main Outcome Measure :Occurrence of AF during the first 84 hours after cardiac surgery.
主要观察终点:心脏术后48小时内发生房颤。
Results : The incidence of postoperative AF was significantly lower in the hydrocortisone group (36/120 [30%]) than in the placebo group (58/121 [48%]; adjusted hazard ratio, 0.54; 95% confidence interval, 0.35-0.83; P = .004; number needed to treat, 5.6). Compared with placebo, patients receiving hydrocortisone did not have higher rates of superficial or deep wound infections, or other major complications.
结果:氢化考的松组术后房颤的发生率(36/120 [30%])显著低于安慰剂组(58/121 [48%] ;调整后的风险比数,0.54 ;95%可信区间,0.35-0.83;p=0.004;需要治疗的人数,5.6人。与安慰剂组相比,接受氢化考的松的患者浅表或深部伤口感染率或其他主要并发症的发生率没有升高。
Conclusion : Intravenous hydrocortisone reduced the incidence of AF after cardiac surgery
结论:静脉输注氢化考的松可以减少心脏术后房颤的发生率。

皮质类固醇激素预防心脏手术后房颤:一项随机对照试验
近日,Jari Halonen等人发表在JAMA上的一项随机双盲对照试验显示,心脏外科手术后静脉输注皮质类固醇激素能预防术后房颤的发生。(JAMA. 2007;297:1562-1567)
心房颤动(AF)是心脏外科术后最常见的心律失常。过度的炎症反应被认为是其病因之一。从2005年8月到2006年7月,在芬兰3家大学医院,共入选241名患者,既往没有房颤或房扑,计划行常规体外循环下冠状动脉旁路移植术(CABG),主动脉瓣置换术,或者冠状动脉旁路移植+主动脉瓣置换术。患者被随机分为接受100mg氢化考的松或匹配安慰剂,给药方法如下:首剂在手术日当天晚上,然后每8小时一次×3天。此外,所有患者均根据心律给与口服美托洛尔(50-150mg/d)。主要观察终点是心脏术后48小时内发生房颤。结果发现,氢化考的松组术后房颤的发生率(36/120 [30%])显著低于安慰剂组(58/121 [48%] ;调整后的风险比数,0.54 ;95%可信区间,0.35-0.83;p=0.004;需要治疗的人数,5.6人)。与安慰剂组相比,接受氢化考的松的患者浅表或深部伤口感染率或其他主要并发症的发生率没有升高。因此,研究认为,静脉输注氢化考的松可以减少心脏术后房颤的发生率。 |
