Abstract

Background

Studies evaluating the impact of functional significance of coronary artery stenosis-based decision-making on results after coronary artery bypass grafting (CABG) are limited.

Objectives

This study was conducted to evaluate the predictive value of preoperative angiography-derived Murray law–based quantitative flow ratio (μFR) of target native coronary arteries on 1-year graft patency following CABG.

Methods

A total of 809 patients who underwent isolated off-pump CABG for 3-vessel disease and 1-year graft evaluation were retrospectively enrolled. Preoperative μFR data were obtained for all feasible target vessels. Multivariable analyses were conducted using generalized linear mixed-effects models. The minimal P value approach was used to determine the optimal cutoff value of the μFR that predicting graft patency.

Results

The mean age of the study population was 65.9 ± 9.0 years. A total of 2,324 distal anastomoses were included in the analysis. Early and 1-year graft occlusion rates were 0.8% (19 of 2,324 anastomoses; 95% CI: 0.5-1.3 anastomoses) and 5.1% (118 of 2,324 anastomoses; 95% CI: 4.2-6.1 anastomoses), respectively. Multivariable analysis demonstrated that μFR was significantly associated with 1-year graft patency (OR [95% CI]: 0.847 [0.731-0.982]; P = 0.03), but not with early graft patency (0.941 [0.746-1.186]; P = 0.60). The minimal P value approach identified μFR values between 0.75 and 0.78 having the strongest discriminative power, with the lowest P value at a μFR of 0.77.

Conclusions

The functional significance of coronary artery stenosis of target vessels, as measured by μFR, is associated with 1-year graft patency after off-pump CABG with an optimal cutoff value of 0.77 (Association Between ΜFR and CABG Outcomes; NCT06844721)

基于默里定律的血管造影定量血流比与1年冠状动脉搭桥术通畅的关系

评估冠状动脉狭窄决策对冠状动脉旁路移植术（CABG）后结果的功能意义的研究有限。目的评价术前血管造影默里定律（Murray laws）靶冠状动脉定量血流比（μFR）对冠脉搭桥术后1年移植物通畅的预测价值。方法回顾性分析809例因3支血管病变行非体外循环冠状动脉搭桥并进行1年移植物评估的患者。术前获取所有可行靶血管的μFR数据。采用广义线性混合效应模型进行多变量分析。采用最小P值法确定预测移植物通畅程度的最佳μFR截止值。结果研究人群平均年龄为65.9±9.0岁。总共有2324个远端吻合口被纳入分析。早期和1年移植血管闭塞率分别为0.8%（19例/ 2324例，95% CI: 0.5 ~ 1.3例）和5.1%（118例/ 2324例，95% CI: 4.2 ~ 6.1例）。多变量分析表明，μFR与1年移植物通畅程度有显著相关性（OR [95% CI]: 0.847 [0.731-0.982]; P = 0.03），但与早期移植物通畅程度无显著相关性（0.941 [0.746-1.186];P = 0.60）。最小P值法对0.75 ~ 0.78 μFR值的鉴别能力最强，最小P值法对0.77 μFR值的鉴别能力最低。结论靶血管狭窄的功能意义（μFR）与非体外循环冠脉搭桥术后1年冠脉通畅相关，最佳临界值为0.77 （ΜFR与冠脉搭桥结局的相关性；NCT06844721）。
