To assess the quality of life in patients undergoing myocardial revascularization using the six-minute walk test.
Prospective observational study with patients who undergoing CABG. The clinical variables, the sixminute walk test, and the SF-36 test were recorded. The patients were assessed at the preoperative time and at 2 months of postoperative period. According their six-minute walk test results, the patients were divided into two groups: group walked more than 350 meters (> 350 meters Group) and the group walked less than 350 meters (< 350 meters Group) at the preoperative time.
Eight-seven patients were included. Age was comparable in both groups (59 ± 9.5 years vs. 61 ± 9.3 years; respectively, P = 0.24). The group walked > 350 meters distance was higher than the < 350 meters group after 2 months of operation (436 ± 78 meters vs. 348 ± 87 meters; P <0.01). The quality of life was lower in the < 350 meters group compared to the > 350 meters group in the preoperative period in the following domains: functional capabilities, limitations due to physical aspects, overall health feelings, vitality, and social aspects. Quality of life improved after two months in both groups.
The six-minute walk test at the preoperative time is associated with the quality of life after two months of coronary artery bypass grafting. In overall, quality of life has improved in all patients. The improvement in the quality of life was greater in those patients who walked distances lower than 350 meters at the preoperative time.
使用六分钟步行试验评估接受心肌血运重建术患者的生活质量。
对接受冠状动脉旁路移植术（CABG）的患者进行前瞻性观察研究。记录临床变量、六分钟步行试验和SF-36测试结果。在术前和术后2个月对患者进行评估。根据术前六分钟步行试验结果，将患者分为两组：术前步行超过350米的组（>350米组）和术前步行少于350米的组（<350米组）。
纳入87例患者。两组年龄相当（分别为59±9.5岁和61±9.3岁；P=0.24）。术后2个月，步行距离>350米的组高于<350米的组（436±78米对348±87米；P<0.01）。在术前，<350米组在以下领域的生活质量低于>350米组：功能能力、身体方面的限制、总体健康感受、活力和社会方面。两组术后2个月生活质量均有所改善。
术前六分钟步行试验与冠状动脉旁路移植术后2个月的生活质量相关。总体而言，所有患者的生活质量均有所改善。术前步行距离低于350米的患者生活质量改善更大。
