Frailty is associated with poorer outcomes in cardiac surgery, but the heterogeneity in frailty assessment tools makes it difficult to ascertain its true impact in cardiac surgery. Slow gait speed is a simple, validated, and reliable marker of frailty. We performed a systematic review and meta-analysis to examine the effect of slow gait speed on postoperative cardiac surgical patients.

慢步态与心脏手术术后较差的预后相关：系统评价和荟萃分析

虚弱与心脏手术的较差结果相关，但虚弱评估工具的异质性使其难以确定其对心脏手术的真正影响。缓慢的步态是一种简单、有效且可靠的虚弱标志。我们进行了系统回顾和荟萃分析，以检查慢步态对术后心脏手术患者的影响。
