The left internal thoracic artery to the left anterior descending artery graft is recognized as the gold standard for coronary revascularization. We compared quality of life (QoL) in patients who received bilateral internal thoracic arteries (BITA) and those with a single internal thoracic artery (SITA) graft.
To assess QoL during a 10-year follow-up in patients who underwent coronary artery bypass grafting (CABG) with BITA vs. SITA.
We recruited 300 patients with multivessel coronary artery disease who underwent CABG from January 2005 to October 2010. Mean duration (standard deviation - SD) of follow-up was 3568 ±409 days. QoL was measured subjectively using a Likert scale and objectively by the WHOQOL-BREF questionnaire. Patients were interviewed by telephone.
BITA patients reported marked improvement and improvement more often than SITA patients (58% vs. 43.3%, = 0.02). Marked deterioration was noted by 2% of BITA patients and 3.3% of SITA patients ( = 0.03). Summarized results of the WHOQOL-BREF questionnaire showed significantly better QoL in the BITA group (median: 15.0) vs. SITA group (median: 14.75) ( = 0.02). There were more angina-free patients in the BITA group (84%) compared to SITA patients (72.7%) ( = 0.006). QoL did not correlate with patients' body mass index ( = 0.10) or residence status ( = 0.51), but there was a weak negative correlation between QoL and patients' age ( = -0.14, = 0.01).
Surgical coronary revascularization using BITA improves QoL, particularly when measured by a Likert scale.
左乳内动脉至左前降支动脉搭桥术被公认为冠状动脉血运重建的金标准。我们比较了接受双侧乳内动脉（BITA）和单侧乳内动脉（SITA）搭桥术患者的生活质量（QoL）。
评估接受BITA与SITA冠状动脉旁路移植术（CABG）患者在10年随访期间的生活质量。
我们招募了2005年1月至2010年10月期间接受CABG的300例多支冠状动脉疾病患者。随访的平均时长（标准差-SD）为3568±409天。生活质量通过李克特量表进行主观测量，并通过世界卫生组织生活质量简表（WHOQOL-BREF）进行客观测量。通过电话对患者进行访谈。
BITA患者报告有明显改善和改善的比例高于SITA患者（58%对43.3%，P=0.02）。2%的BITA患者和3.3%的SITA患者出现明显恶化（P=0.03）。WHOQOL-BREF问卷的汇总结果显示，BITA组的生活质量明显优于SITA组（中位数：15.0）对SITA组（中位数：14.75）（P=0.02）。BITA组无心绞痛患者的比例（84%）高于SITA患者（72.7%）（P=0.006）。生活质量与患者的体重指数（P=0.10）或居住状况（P=0.5１）无关，但生活质量与患者年龄之间存在较弱的负相关（P=-0.14，P=0.01）。
使用BITA进行外科冠状动脉血运重建可改善生活质量，尤其是通过李克特量表测量时。
