摘要:
目的:探讨术前血浆N末端脑钠尿肽原(NT-proBNP)水平对老年腹部手术患者围手术期严重心血管事件(PMCE)的预测价值。方法: 检测173例拟实施腹部手术老年患者的术前血浆NT-proBNP浓度,通过ROC曲线下面积比较术前血浆NT-proBNP水平和修订心脏风险指数(RCRI)在预测老年腹部手术患者围手术期发生PMCE的价值并找出理想截断点值。结果: 围手术期发生PMCE 12例,PMCE组血浆NT-proBNP浓度显著高于无PMCE组,中位数分别为452.6 ng/L和67.1 ng/L,NT-proBNP-log分别为2.72±0.43和1.82±0.39,P<0.01。术前血浆NT-proBNP的ROC曲线下面积为0.964(95%CI 0.924-0.986,P<0.01),RCRI的ROC曲线下面积为0.79(95%CI 0.722-0.848,P<0.01),二者的曲线下面积比较相差0.174,P<0.05。NT-proBNP预测围手术期PMCE的截断点为230.2 ng/L,其诊断灵敏度、特异度和准确度分别为92% 、96%和 96%。结论: 术前血浆NT-proBNP能预测老年腹部手术患者PMCE的发生,可以作为术前风险评估的工具。
Abstract:
AIM:To investigate the value of N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in predicting perioperative major cardiovascular events (PMCE) in elderly patients undergoing abdominal surgery. METHODS: NT-proBNP was determined preoperatively in 173 patients undergoing surgery. ROC analyses were performed to evaluate the predictive values of plasma NT-proBNP and revised cardiac risk index (RCRI) for perioperative PMCE in elderly patients undergoing abdominal surgery and to identify the optimal NT-proBNP cut-off for predicting perioperative PMCE. RESULTS: Twelve patients developed perioperative complications of PMCE. Preoperative NT-proBNP levels were significantly higher in patients experiencing cardiac events compared with the levels in patients without events (median 452.6 ng/L vs. 67.1 ng/L; NT-proBNP-log 2.72/0.43 vs. 1.82/0.39, P<0.01). In a receiver-operator characteristic (ROC) analysis for the prediction of PMCE, the area under ROC curve for NT-proBNP was significantly higher than the area under ROC curve for RCRI (0.964, 95% CI 0.924-0.986, P<0.01) vs. 0.79, 95% CI 0.722-0.848, P<0.01) (P<0.05). The optimal predictive accuracy was achieved with a NT-proBNP threshold of 230.2 ng/L. CONCLUSION: In elderly patients undergoing abdominal surgery, preoperative NT-proBNP level can predict short-term postoperative PMCE. NT-proBNP is a useful tool in the preoperative evaluation of elderly patients undergoing abdominal surgery.
