Background. The prognostic value of cardiopulmonary exercise testing (CPET) is known, but the predictive value of 6MWT in patients with heart failure (HF) and patients undergoing coronary artery bypass grafting (CABG) is not established yet. Objective. We conducted a systematic review exploring the prognostic value of 6MWT in HF patients undergoing cardiac surgery. The aim was to find out whether the change in the distance walked during follow-up visits was associated with prognosis. Data Source. We searched "PubMed" from January 1990 to December 2012 for any review articles or experimental studies investigating the prognostic value of 6MWT in HF patients and patients undergoing cardiac surgery. Results. 53 studies were included in the review, and they explored the role of 6MWT in cardiology, cardiac surgery, and rehabilitation. The results did not show the relation between the six-minute walk distance and adverse events after CABG. The predictive power of the distance walked for death in HF patients undergoing cardiac surgery was not found. It is not yet proved if the change in the six-minute walk distance is associated with prognosis. The predictive power of the six-minute walk distance for death in HF patients undergoing cardiac surgery remains unclear.
背景。心肺运动试验（CPET）的预后价值已为人所知，但6分钟步行试验（6MWT）在心力衰竭（HF）患者和接受冠状动脉旁路移植术（CABG）患者中的预测价值尚未确立。目的。我们进行了一项系统评价，探讨6MWT在接受心脏手术的HF患者中的预后价值。目的是查明随访期间步行距离的变化是否与预后相关。数据来源。我们检索了1990年1月至2012年12月的“PubMed”，以查找任何调查6MWT在HF患者和接受心脏手术患者中的预后价值的综述文章或实验研究。结果。该综述纳入了53项研究，这些研究探讨了6MWT在心脏病学、心脏手术和康复中的作用。结果未显示6分钟步行距离与CABG术后不良事件之间的关系。未发现步行距离对接受心脏手术的HF患者死亡的预测能力。6分钟步行距离的变化是否与预后相关尚未得到证实。6分钟步行距离对接受心脏手术的HF患者死亡的预测能力仍不清楚。
