Abstract

Objectives. The One-minute Sit-To-Stand Test (STST) is a relatively novel physical performance test in the field of pulmonology. It measures the exercise tolerance of the patient. In this pilot study, we evaluated its predictive value for the postoperative course in cardiac surgery patients. Design. This was a prospective observational cohort study of patients undergoing elective aortic valve replacement. STST was applied in the patients, along with pulmonary function testing, a day prior to surgery, on postoperative day 7, and 3 months after surgery. A Short Form-36 health related quality of life survey (SF-36) was also included. The patients were divided into two groups according to the preoperative STST outcome: group A (≤20 repetitions, n = 12), and group B (>20 repetitions, n = 18). Results. We enrolled 30 patients in the study between May 2017 and May 2019. No complication were observed during the STST. The standard perioperative measures were identical for both groups. However, group A exhibited a significantly longer artificial ventilation time, as well as worse pulmonary function (VC, FVC, TL_CO), on postoperative day 7. Concerning the SF-36, group A displayed a worse pre- and postoperative evaluation in both physical functioning and vitality. Conclusions. STST is a short and practical physical performance test that could enable a better prediction of the postoperative course after cardiac surgery. Patients with lower preoperative STST performance may require longer postoperative artificial ventilation, as they may present worse in some parameters of pulmonary functions and quality of life. However, these findings must be corroborated in larger studies.

摘要

目标。一分钟坐到站测试 (STST) 是肺病学领域中一种相对新颖的物理性能测试。它测量患者的运动耐量。在这项初步研究中，我们评估了其对心脏手术患者术后病程的预测价值。设计。这是一项针对接受选择性主动脉瓣置换术的患者的前瞻性观察队列研究。在手术前一天、术后第 7 天和手术后 3 个月，对患者进行 STST 和肺功能测试。还包括一个简短的 Form-36 健康相关生活质量调查 (SF-36)。根据术前 STST 结果将患者分为两组：A 组（≤20 次重复，n = 12）和 B 组（> 20 次重复，n  = 18）。结果。我们在 2017 年 5 月至 2019 年 5 月期间招募了 30 名患者。在 STST 期间未观察到并发症。两组的标准围手术期措施相同。然而，A 组在术后第 7 天表现出明显更长的人工通气时间，以及更差的肺功能（VC、FVC、TL _CO）。关于 SF-36，A 组在这两个方面表现出更差的术前和术后评估身体机能和活力。结论。STST 是一项简短而实用的身体机能测试，可以更好地预测心脏手术后的术后病程。术前 STST 表现较差的患者可能需要更长时间的术后人工通气，因为他们的肺功能和生活质量的某些参数可能更差。然而，这些发现必须在更大的研究中得到证实。
