摘要:

文题释义:
全关节置换术:是治疗晚期髋、膝关节疾病的重要手段,包括全髋关节置换术和全膝关节置换术。是通过手术将人工髋/膝关节假体置入患者髋/膝关节部位,以替代原有的病损关节,达到缓解疼痛、恢复下肢力线、改善关节功能及患者生活质量的目的。
全关节置换术后心肌梗死:心肌梗死是全关节置换患者术后危重并发症,其发病突然、进展迅速,常造成严重的不良后果。既往研究报道下肢关节置换术后心肌梗死的发生率为0.18%-1.8%。

背景:心肌梗死是全关节置换患者术后危重并发症。目前,尚无研究报道全关节置换术后心肌梗死的危险因素及预测模型。
目的:探讨全关节置换患者术后心肌梗死的发生率及危险因素,并建立预测全关节置换患者术后心肌梗死的临床预测模型。
方法:回顾性分析2013年9月至2017年7月于青岛大学附属医院及西秀区人民医院行全髋关节置换或全膝关节置换术的5 746例患者资料。收集并记录患者基本信息、并存疾病、术前检查、手术信息、住院其他信息及随访资料,分析患者发生心肌梗死的相关危险因素,并基于独立危险因素建立预测全关节置换患者术后心肌梗死的列线图。利用受试者工作特征曲线(ROC)及校正曲线对列线图进行评价。
结果与结论:48例患者术后14 d内出现心肌梗死,发生率为0.8%。多因素Logistic回归结果表明年龄校正后的查尔森共病指数(age-adjusted Charlson comorbidity index,aCCI)、麻醉方式和术前合并房颤为全关节置换术后心肌梗死的独立危险因素(P < 0.05)。其中,aCCI≥5的患者发生心肌梗死的风险显著高于aCCI<5的患者,手术中采用全身麻醉的患者术后发生心肌梗死的风险显著高于采用硬膜外麻醉/腰麻的患者,而术前合并房颤的患者其术后发生心肌梗死的风险显著高于无房颤患者。ROC曲线表明列线图具有较高的区分度(AUC=0.730,95%CI:0.661-0.799),校准曲线表明模型具有较高的校准度。基于aCCI、麻醉方式和房颤3项指标的预测模型可准确预测全关节置换患者术后心肌梗死的发生概率。

Abstract: BACKGROUND: Myocardial infarction is one of the catastrophic complications after total joint arthroplasty. However, the risk factors and predictive model have not been reported in previous research after total joint arthroplasty. 
OBJECTIVE: To study the incidence and risk factors of myocardial infarction after total joint arthroplasty, and develop a nomogram for predicting the myocardial infarction after total joint arthroplasty.
METHODS: We retrospectively reviewed the data of 5 746 patients who underwent total hip arthroplasty or total knee arthroplasty in the Affiliated Hospital of Qingdao university and the People’s Hospital of Xixiu District between September 2013 and July 2017. The baseline characteristic, preoperative comorbidities, preoperative examinations, operative data, other hospital information and follow-up data were collected, recorded and were used to analyze the risk factors of myocardial infarction. In addition, a nomogram was developed based on the independent risk factors for predicting the myocardial infarction after total joint arthroplasty, and receiver operating characteristic curve and calibration curve were used to evaluate the nomogram. 
RESULTS AND CONCLUSION: Forty-eight patients affected myocardial infarction within 14 days after total joint arthroplasty, and the incidence of myocardial infarction was 0.8%. Multivariate Logistic analysis indicated that age-adjusted Charlson Comorbidity Index, anesthesia type and atrial fibrillation were independent risk factors for postoperative myocardial infarction (P < 0.05). The risk of myocardial infarction in patients with age-adjusted Charlson Comorbidity Index ≥ 5 was higher than patients with age-adjusted Charlson Comorbidity Index < 5. The risk of myocardial infarction in patients receiving general anesthesia was higher than that of patients receiving epidural/lumber anesthesia. The risk of myocardial infarction in patients combined with atrial fibrillation was higher than that in patients without it. Receiver operating characteristic curve showed that the nomogram has a high degree of discrimination (AUC=0.730, 95%CI: 0.661-0.799), and the calibration curve showed that the model had a high degree of calibration. A predictive model based on age-adjusted Charlson Comorbidity Index, anesthesia type and atrial fibrillation can accurately predict the myocardial infarction following total joint arthroplasty.
