Previous study found that C-reactive protein (CRP) can predict bleeding after on-pump CABG. To evaluate whether preoperative C-reactive protein (CRP) can be a novel marker of postoperative bleeding in patients having off-pump coronary artery bypass grafting (CABG).
This is a retrospective cohort study. Multiple variable regression analyses were performed. 537 patients undergoing off-pump isolated primary CABG at Fuwai Hospital from September 2017 to July 2018 were recorded. The primary endpoint was bleeding volume within 24 h after surgery.
Data of 537 patients undergoing off-pump isolated primary CABG at Fuwai Hospital were recorded. The correlations between bleeding volume within 24 h after surgery and preoperative data were analyzed with univariate and multivariate linear regression. Much more preoperative CRP concentration (B = -0.089, P < 0.05) was associated with less postoperative bleeding volume and fibrinogen (B = 0.594, p < 0.001).
Preoperative CRP concentration is independently correlated with the postoperative volume of bleeding within 24 h. CRP may become a novel coagulation index in coronary artery atherosclerotic disease.
先前的研究发现 C 反应蛋白（CRP）可预测体外循环冠状动脉旁路移植术（CABG）后的出血情况。本研究旨在评估术前 C 反应蛋白（CRP）是否可以作为体外循环冠状动脉旁路移植术（CABG）患者术后出血的新型标志物。
本研究为回顾性队列研究。进行了多变量回归分析。记录了 2017 年 9 月至 2018 年 7 月在阜外医院行非体外循环单纯冠状动脉旁路移植术的 537 例患者的数据。主要终点为术后 24 小时内的出血量。
记录了 537 例在阜外医院行非体外循环单纯冠状动脉旁路移植术的患者的数据。使用单因素和多因素线性回归分析了术后 24 小时内出血量与术前数据之间的相关性。术前 CRP 浓度（B=-0.089，P<0.05）与术后出血量和纤维蛋白原（B=0.594，P<0.001）呈负相关。
术前 CRP 浓度与术后 24 小时内出血量独立相关。CRP 可能成为冠状动脉粥样硬化性疾病的新型凝血指标。
