Abstract：
BACKGROUND: The aim of the study was to analyze the Canadian Cardiovascular Society (CCS) guidelines for routine postoperative troponin testing after elective total hip arthroplasty (THA) to reduce the mortality rate resulting from myocardial injury. The purpose of this study was to assess the prognostic relevance of implementing these guidelines to minimize cardiac events in patients undergoing elective THA.
METHODS: Patients who underwent THA surgery in 2020 were included in the study. The inclusion criteria were elective THA patients aged ≥45 years, while emergency, revision, and simultaneous bilateral THA surgeries were excluded. The patients were categorized into 4 groups based on the CCS guidelines.
RESULTS: The study included 669 patients who had an average age of 67 years. There were 43 patients (6.4%), who experienced a rise in troponin levels ≥30 ng/L and developed myocardial injury after noncardiac surgery. Among these patients, 8 developed cardiac complications, and one experienced a serious cardiac event that resulted in death. Notably, there was a significant increase in the length of hospital stay for patients who received the postoperative screening protocol.
CONCLUSIONS: The implementation of the CCS guidelines for routine postoperative troponin testing in elective THA surgery did not significantly decrease the rate of cardiac events or mortality.

摘要：
背景：本研究的目的是分析加拿大心血管学会（CCS）指南中关于选择性全髋关节置换术（THA）后常规术后肌钙蛋白检测的指导原则，以降低心肌损伤导致的死亡率。这项研究的目的是评估实施这些指南以最大程度地减少接受选择性THA的患者的心脏事件的预后相关性。
方法：将2020年接受THA手术的患者纳入研究。纳入标准为年龄≥45岁的选择性THA患者，在紧急情况下，修订版,排除了同时进行的双侧THA手术。根据CCS指南将患者分为四组。
结果：该研究包括669名平均年龄为67岁的患者。有43名患者(6.4%),在非心脏手术（MINS）后，肌钙蛋白水平升高≥30ng/L并发生心肌损伤。在这些患者中,八个发展的心脏并发症，其中一人经历了导致死亡的严重心脏事件。值得注意的是,接受术后筛查方案的患者的住院时间显著延长.
结论：在选择性THA手术中实施常规术后肌钙蛋白检测的CCS指南并未显著降低心脏事件或死亡率。
