目的：评估5项改良衰弱指数（mFI-5）与非心肺转流冠状动脉搭桥手术（OPCABG）老年患者预后的相关性。
方法：回顾性收集2019年1月至2022年5月接受OPCABG的老年患者资料，根据术前mFI-5将患者分为三组：非衰弱组（mFI-5=0分）、衰弱前期组（mFI-5=1分）和衰弱组（mFI-5≥2分）。收集三组患者的基线、术中及预后指标。采用多变量（Logistic回归及线性回归）分析评估mFI-5与OPCABG患者预后的相关性。
结果：共有244例患者纳入分析，其中非衰弱组35例（14.3%），衰弱前期组82例（33.6%），衰弱组127例（52.1%）。与非衰弱组比较，衰弱前期组急性肾损伤发生率明显升高（P<0.05）；衰弱组术前LVEF明显降低，术中尿量明显减少，急性肾损伤发生率和死亡率明显升高（P<0.05）。与衰弱前期组比较，衰弱组术中尿量明显减少，ICU住院时间明显延长，死亡率明显升高（P<0.05）。多因素Logistic回归分析结果显示，mFI-5每升高1分，ICU住院时间延长3.189 d（95%CI 1.457～4.920 d，P<0.001），总住院时间延长2.890 d（95%CI 1.070～4.709 d，P=0.002）。线性回归分析结果显示，mFI-5升高与住院期间并发症的发生相关，包括急性肾损伤（OR=1.519，95%CI 1.076～2.145，P=0.017）、肺部并发症（OR=1.453，95%CI 1.075～1.965，P=0.015）和死亡（OR=3.730，95%CI 1.980～7.027，P<0.001）。
结论：mFI-5量表是一种简便实用的衰弱筛查工具，对OPCABG老年患者采用mFI-5量表进行衰弱评估，可以筛选出住院期间不良预后的高危患者。 |

Objective: To evaluate the association between 5-factor modified frailty index (mFI-5) with prognosis in elderly patients undergoing off-pump coronary artery bypass grafting (OPCABG).
Methods: Retrospective data were collected from elderly patients who underwent OPCABG between January 2019 and May 2022. The patients were divided into three groups based on preoperative mFI-5: non frailty group (mFI-5 = 0), pre-frailty group (mFI-5 = 1), and frailty group (mFI-5 ≥ 2). Baseline, intraoperative, and prognostic indicators of the three groups were collected and compared. Multivariate (logistic regression and linear regression) analyses were used to evaluate the association between mFI-5 with prognosis in elderly patients undergoing OPCABG.
Results: A total of 244 patients were included in the analysis, including 35 patients (14.3%) in the non-frailty group, 82 patients (33.6%) in the pre-frailty group, and 127 patients (52.1%) in the frailty group. Compared with the non-frailty group, the pre-frailty group had higher incidence of acute kidney injury (P < 0.05); the frailty group had lower preoperative LVEF and intraoperative urine volume, and higher incidence of acute kidney injury and mortality (P < 0.05). Compared with the pre-frailty group, the frailty group had lower intraoperative urine volume, prolonged ICU stay, and higher incidence of mortality (P < 0.05). Multivariate logistic regression analysis showed that for every point increase in mFI-5, the length of stay in ICU was extended by 3.189 days (95% CI 1.457-4.920 days, P < 0.001), and the total length of stay was extended by 2.890 days (95% CI 1.070-4.709 days, P = 0.002). Linear regression analysis showed that elevated mFI-5 was associated with complications during hospitalization, including acute kidney injury (OR = 1.519, 95% CI 1.076-2.145, P = 0.017), pulmonary complications (OR = 1.453, 95% CI 1.075-1.965, P = 0.015) and death (OR = 3.730, 95% CI 1.980-7.027, P < 0.001).
Conclusion: mFI-5 is a simple and practical screening tool for frailty, and using the mFI-5 scale for frailty assessment in elderly patients undergoing OPCABG can screen high-risk patients with poor prognosis during hospitalization. |
